Iron Soft Close Cup Hinge Three Positions G-F877H

The G-F877H In Five Staged Frames And Three Position Drawings

This listing is written from the six frames on this page, and what they show is a cup cabinet hinge in bright nickel plated iron: the group frame of five hinges in slightly different positions, three position drawings of the same hinge each with its opening geometry and its note, a single hinge opened at the joint with the damper piston and the spring barrel visible in the knuckle section, a side view of the cast cup body with the two hole mounting plate, and a four panel grid of the hinge in four further positions. The drawings state the specification as 115 by 62 millimetres and the material as iron, and the model designation in the folder marks this as the hydraulic, damped member of the cup hinge family, so this page carries each of those points and is honest about which of them the photographs prove and which the drawing carries.

Two points are stated plainly rather than implied. First, the damper is readable as a part in the opened close up frame: the piston and the spring barrel in the knuckle section, and the dark cartridge at the tail of the body in the four panel grid, and that is the closing mechanism on a hydraulic hinge of this class, but what a photograph proves is the part being there, not the closing feeling, so the soft close behaviour is confirmed from the drawing and felt on a sample before the production order is cut. Second, the cup bore, the door load and the cycle count are not numbers a photograph can give, and the specification table says they come from the drawing rather than from any figure on this page.

The Damper The Photographs Can See

A soft close hinge of this class carries its closing mechanism in the body, and the opened close up frame shows it directly: the damper piston and the spring barrel visible in the knuckle section between the two arms, and the four panel grid catches the dark cartridge at the tail of the body from a second angle. That is the part that takes the door's energy in the last degrees of the swing so the door comes to rest against the case instead of striking it. The photographs put the part in view rather than hiding it, which is the difference between a damper that is drawn on the drawing and one that is in the hinge you are looking at, and it is the part a buyer is actually purchasing when they specify the soft close on a cup hinge.

What the photographs do not prove is the closing feel. A hinge can carry the damper and still close hard if the case is built wrong, the door is heavy for the hinge, or the hinge is fixed crooked, so the soft close behaviour is confirmed two ways before an order: the drawing states the closing class, and the sample is worked through its full swing in the buyer's own board, where the last degrees of the swing are what a buyer actually buys. The damper is visible in the frames; the closing is something the sample proves.

Three Drawings, Three Positions Of The Same Hinge

The three position drawings are the clearest frames in this listing, because each one shows the same hinge with its own opening geometry and its own note, and together they say what a single photograph of the part cannot say, which is how this hinge meets the case in three different cabinet constructions. The first drawing is the full overlay position: the closed door stands out over the case, the note reads that the cabinet door is flush with the side panel, and that is the position a standalone cabinet or an end of a run takes. The second is the half overlay position, the note reading that the cabinet door and the side panel share the opening, and that is the position the two doors of a matched pair take, each covering half the shared carcass edge. The third is the inset position, the note reading that the cabinet door fully opens into the side panel, and that is the position a framed, recessed door takes, flush inside the case rather than over it.

The point a buyer should hold from these three drawings is that the same hinge, the same part number, covers three different cabinet geometries, and the difference between them is the plate and arm geometry against the case, not a different hinge. A full overlay hinge, a half overlay hinge and an inset hinge from one part number is the kind of range that simplifies a production order, because the warehouse stocks one hinge and the fitter chooses the position by the case in front of them. The drawings carry the geometry note for each position, and the sample carries the closing, so the position is confirmed at the drawing and the closing at the bench.

What The Frames In This Listing Prove

Every structural claim on this page can be pointed at in one of the six frames: the cast cup and its two hole mounting plate in the side view, the group of five hinges in the group frame, the damper piston and the spring barrel in the opened close up, the dark cartridge at the tail of the body in the four panel grid, the adjustment screws on the arm, and the three opening positions in the three drawings. What no frame on this page proves is the cup bore, the door load limit or the cycle count, so none of those figures is carried as a photograph fact. They come from the hinge drawing and the test report, and a figure borrowed from a similar hinge is the most expensive kind of typo in a workshop, so they are issued against this model rather than assumed.

The staged set also omits, on purpose, the remaining frames of this folder that repeat the same positions at slightly different angles. What remains is six different views of the hinge, and each of the six is used once in the image gallery on this page.

How The Hinge Is Built

The side view frame is the clearest way to read a hinge of this kind: the cast cup at one end where the door is bored, the two hole plate behind it where the door fixing sits, the arm between them carrying the adjustment screws, the knuckle section where the body pivots, and the stamped case plate at the foot. Three things about this construction are worth a buyer knowing before the drawing arrives. First, the cup is a cast body rather than a pressed one, and the side view shows the cast radius at the cup base where a pressed cup would show a seam, which is what carries the door load through the recess without concentrating it at one point. Second, the arm carries the adjustment screws, and that is what makes the door position settable at the screw after fitting rather than fixed at the plate. Third, the damper sits in the knuckle section where the opened frame shows the piston and the spring barrel, so the closing runs through the joint itself rather than through an add on piece clipped to the plate.

• Cast cup in bright nickel, the part that drops into its recess in the door.
• Two hole mounting plate behind the cup, carrying the door fixing.
• Stamped case plate at the foot, the fixing that sits on the carcass.
• Arm with its adjustment screws, the door position set at the screw.
• Damper piston and spring barrel in the knuckle section, visible in the opened frame.
• Dark cartridge at the tail of the body, visible in the four panel grid.
• Knuckle at the joint where the body pivots, shown opened in the close up frame.

The Cup And The Plate, And The Position They Make

The cup is the part of a cup hinge that the door is bored for, and the side view frame shows it at the end of the upright hinge, a cast body with the mounting plate carrying its two fixing holes at the back. The bore diameter itself is not a photograph measurement, it is the drawing figure, and a boring jig set to the drawing figure is what cuts the recess, with the hinge then dropped in against it, so the drawing number, not the photograph, is the number the workshop works from, and this page says so because a hinge ordered against the wrong cup bore is a door that never hangs true. The case plate at the foot is the stamped part the carcass screws take, and the drawings show how that plate sits against the case in each of the three positions, which is the geometry that turns one hinge into a full overlay, a half overlay or an inset door.

The material line on the drawings reads iron, and the finish over it is the bright nickel that the frames show on cup, arm and plate alike. An iron hinge in nickel plating is the standard interior cup hinge: the price is right for a door run of twenty or two hundred, the finish is right for a dry cabinet, and it is the wrong call for a wet position, because plating always has pinholes at the knuckle radius where salt and chlorine start. For a wet or coastal cabinet we quote a stainless hinge instead, even though it costs more per fitting, because a hinge that corrodes through in one season costs more than the hinge ever did.

How Many A Door Needs, And Why A Damped Door Leans Up

One of the staged frames is the group shot of five hinges, and the group frame is the count question in picture form, because a door is hung on two hinges at minimum and the set is the unit a door order runs in. Hinge count follows door height and door mass, not preference: two hinges up to a modest height, three above it, and an extra hinge at mid height on a tall or heavy door so the middle of the rail is not carrying the twist. The break points depend on the door and the board, so they are agreed against the drawing rather than assumed on a page. A soft close door is one case where the count argument leans up rather than down: the damped closing loads the fixings through the last few degrees of every swing, which a free swinging door does not do, and a tall door that could manage two standard hinges often wants three of a hydraulic hinge, with the mid fixing holding the line while the closing runs.

The Fitting Sequence A Cup Hinge Runs In

The staged frames put the hinge in view in several positions, and the sequence a fitter works through on a cabinet door runs from those parts in a fixed order. First the case plate hinge half is fixed to the carcass on the drawing centres, two screws in the foot plate, and the hinge is checked square to the case before the door touches it, because a case plate fixed crooked is a hinge that no amount of door adjustment can make hang true. Second the door is bored for the cup at the drawing figure, the recess cut to depth and the pilot holes for the two hole plate set off it. Third the hinge drops into its recess, the two hole plate takes its door screws, and the door is lifted onto the case plate. Fourth the adjustment screws on the arm set the door edge in and out until the gap reads even along the stile, and that is the whole fitting, a cup hinge sequence that runs in that order on every case the hinge meets, which is why the sequence is the same for the full overlay, the half overlay and the inset position alike.

The order matters more than the speed. A hinge bored before the case plate is square is a hinge that carries the case error into the door, and a door hung before the plate is true is a door that settles at the first adjustment screw turn instead of at the second. Fitters who run the sequence out of order report the hinge as hard to set, and the hinge is not hard to set, the sequence is, which is the note the sample exists to settle before the production hinge run is cut.

Doors That Misbehave, And What The Hinge Is Usually Not To Blame For

A door that drops at the bottom over time is almost never the hinge, and on a cup hinge the symptom can look like the hinge working loose in its recess because the hinge carries the whole door load through the cup, but the load path ends at the fixing, and the fixing ends in the board. Chipboard and MDF lose grip at a pilot hole that has been worked repeatedly while a fitter chases the line, and the plate pulls away from the carcass while the hinge sits sound in its recess. The answer is the fixing and the screw gauge, not a heavier hinge, and the drawing names the screw specification for the reason.

A door that will not close is usually a gap question rather than a hinge question. The hinge sets the door edge against the case, and the case geometry sets the gap, so a door that is a millimetre proud along the meeting stile is a door the case built proud, and the adjustment screw moves the edge within its travel but does not move the case. Forcing the closing on that door loads the knuckle at the last degrees, which is how a sound hinge gets blamed for a case error. A door that sticks at one point in the swing is an alignment question the arm screws settle, and on a hydraulic hinge a closing that feels uneven at the last degrees is a door mass question, the damper rated for a door it is not carrying, and the fix is one more hinge at mid height rather than a different damper, because the damper is sealed in the body and not field serviced.

The Damper Is A Part, Not A Service

The opened frame shows the damper piston and the spring barrel as machined parts in the knuckle section, and the point a buyer should take from that is that the closing of this soft close hinge is a built in part of the hinge rather than an add on device clipped to the cup after fitting. The clip on retrofit devices that upgrade an old hinge to soft close are a real product class, and they work, but a hinge that carries the damper in the body has one fewer part to lose, one fewer part to clip on crooked, and a closing that runs through the joint rather than beside it. The four panel grid shows the same damper from the tail of the body, the dark cartridge section, and that second angle is the one that puts the damper in view on a page, because the front views show the hinge working and this one shows the hinge carrying its closing.

Batch Consistency: Why One Hinge Runs Across A Whole Contract

A contract for a run of cabinet doors is where a cup hinge either earns the order or loses it, because the fitter is working off one hinge specification across every door in the job, and a hinge that changes between batches is a gap that changes between doors. The consistency a buyer should hold the supplier to is the hinge itself: the cup diameter batch to batch, the plate centres on the drawing every time, the damper present in every hinge of the soft close run, and the finish even across the cartons. The batch check section above is how the factory holds those points at packing, and the drawing is how the buyer holds them at receipt, because a hinge contract that names the drawing and the model number is a contract that can be checked, and a hinge contract that names only a photograph is one that cannot.

Where This Hinge Is The Right Call, And Where It Is Not

A nickel plated iron cup hinge with a visible damper and three positions belongs inside furniture that needs the door to close gently and the fitting to stay true: wardrobe doors, kitchen doors where a striking door is out of the question, bedroom furniture, office casework, and any casework where the door weight and the swing have to be carried by a hinge a fitter can set in an afternoon and re set in an evening. With the door closed the hinge sits inside the rail and the cup recess, and nothing shows but the door line. It is the wrong call for a marine locker, a hosing down area, a food processing room or an unventilated external cabinet in a coastal position, for the reason the material section says: the finish is a decorative interior finish rather than a marine barrier. The position drawings are the part that makes this hinge a wide call, because a buyer with a mix of full overlay, half overlay and inset doors in one contract can put all three on one part number and stock one hinge.

How This Hinge Sits In Our Range

Within our own hinge range, a buyer choosing a cup hinge is usually choosing between the closing, the position and the plate, in that order. The closing sets how the door comes to rest; the position sets how the door meets the case; and the plate sets how the hinge is fixed. This hinge is specified by all three: the hydraulic soft close closing with the damper visible in the knuckle section, the three positions carried by the three drawings, and the cast cup with the two hole plate. The free swing member of this family is listed under its own model number on the site, and the difference between the two is the closing behaviour, the damper part you can see in the frames on this page but not in the frames of that one. A buyer comparing the two should compare them on the same three points, because the difference is the closing and the position coverage, and both are things a white background photograph shows only partly.

Specification Summary

How Each Hinge Batch Is Checked Before Packing

Every hinge batch is sampled on four points before packing. Assembly: the cup, the arm, the plate and the damper section are checked to be present and seated, the knuckle is checked to sit square rather than cross loaded, and the adjustment screws are checked to run rather than bind. Appearance: the nickel surface is checked for passivation marks, handling scratches and any plating that has pulled at the knuckle radius, which is the part of the hinge that shows first in a lit wardrobe. Function: each sampled hinge is worked through its full swing by hand, opened and closed, so a binding joint or a closing that strikes instead of damping shows up before the carton closes, and the damper section is checked to run through the last degrees without a hard stop. Packing: carton quantity, inner bag, marking and the model number on the label are checked against the order rather than the previous job, and the documents a buyer needs at their own customs are issued with the proforma.

Who Supplies This Hinge

This hinge is supplied by Guangzhou Gorgeous Intelligent Technology Co., Ltd., a furniture and architectural hardware business whose range covers hinges, drawer slides, handles, stays, legs, castors, locks and the fitting sets that go with them. The company works to export orders: quantities, carton marking, barcodes and shipping documents are agreed before production rather than after it, and a buyer who specifies the position, the plate and the screw type on the order gets those things made, because that is the only specification the factory works from.

Terms Worth Agreeing Before Two Hinges Are Compared

• Soft close hinge: a hinge whose closing is damped so the door comes to rest against the case instead of striking it; the damper piston and spring barrel are visible in the knuckle section of the opened frame, and the closing behaviour is confirmed from the drawing and the sample.
• Cup hinge: a hinge that hangs from a cup bored into the door, the cup being the part that drops into its recess; the cast cup is visible in the side view frame, and the bore is the drawing figure.
• Full overlay hinge: the position where the closed door stands out over the case, the first of the three position drawings, for standalone cabinets and the ends of a run.
• Half overlay hinge: the position where the two doors of a matched pair each cover half the shared carcass edge, the second of the three position drawings.
• Inset hinge: the position where the door is recessed inside the case, flush rather than over it, the third of the three position drawings.
• Damper piston and spring barrel: the two parts of the closing mechanism visible in the knuckle section of the opened frame, the hardware the soft close designation is built on.
• Drawing: the document that turns a hinge photograph into a hinge specification; the position notes, the 115 by 62 figure and the iron material line all come from it, and we send it with the quotation.
• Overlay: how far a closed door sits over the case; each position drawing shows it for its geometry, and the case has to allow it.
• Fixing holes: the holes that carry the door screws on the plate and the case screws on the foot; the pilot hole and screw gauge are part of the holding, not just the hinge.
• Free swing: the closing class of the sibling model listed under its own model number, the same hinge without the damper part this page shows.

Common Hinge Faults And What They Actually Mean

A door that drops over time is almost always a fixing problem rather than a hinge problem. The hinge is the strongest part of that joint; the board it is screwed into is not. In chipboard and MDF the holding power depends on the pilot hole and the screw gauge, and a plate that has been screwed and unscrewed repeatedly while a fitter chases the line loses grip, which shows up later as the plate pulling away from the carcass while the hinge itself is still sound. On a cup hinge the symptom can look like the hinge working loose in its recess, because the hinge carries the door load through the cup, and the answer is still the fixing, not a heavier hinge.

A door that will not square up is usually an adjustment question on a hinge of this class: the screws set the door edge, and a screw that is at the end of its travel means the hinge is being asked to correct a gap the case does not have, which is a case geometry problem wearing a hinge costume. The answer is checking the case edge against the drawing and the sample, not forcing the door or swapping the hinge for one nobody has specified. On a hydraulic hinge a closing that feels hard or uneven at the last degrees is an alignment or a door load question, and both are fixed at the bench with the sample door, which is why the sample comes first on a new case: the buyer feels the closing in their own board before the production order is cut.

The faults that actually do come from the hinge are the cup, the plate and the arm: a cup that does not seat in its recess because the boring is wrong for it, a plate that was fixed crooked, an arm that was bent during fitting, and screws that were driven over the top instead of home. None of those is a hinge defect, but they all show up as one, and the way to keep a soft close cup hinge working is the same as the way to keep any hinge working, which is to fix it true the first time with the right screws in the right holes.

Questions Buyers Ask About This Hinge

• Is the G-F877H a soft close hinge? Yes: the model designation marks it as the hydraulic, damped member of the cup hinge family, and the opened frame shows the damper piston and the spring barrel in the knuckle section, with the dark cartridge at the tail of the body in the four panel grid. The photograph proves the part is in the hinge; the closing feel is confirmed from the drawing and demonstrated on a sample in your own board, and we will confirm it in writing before you order.
• How many positions does it do, and how do I choose? Three, and the three position drawings are the choosing tool: the full overlay position for a standalone cabinet or the end of a run, the half overlay position for the two doors of a matched pair, and the inset position for a framed recessed door. The same part number covers all three, so the position is chosen by the case geometry in front of the fitter, not by a different model number.
• What is the cup bore? The cup bore is the model specification on the drawing for this hinge, and it is stated as such on this page rather than as something the photographs measure. The frames show the cup in several positions, and the boring jig is set to the drawing figure against your door material before you cut anything.
• The drawings say iron; is that a problem? It is the standard interior cup hinge construction: iron with a bright nickel plated finish, the right price for a door run and the right finish for a dry cabinet. It is the wrong call for a wet, hosed or coastal position, and for those we quote a stainless hinge instead.
• How many do I need on a tall door? Two up to a modest door height, three above it, and an extra hinge at mid height on a tall or heavy door, because the damped closing loads the fixings through the last degrees of every swing and the mid fixing is what keeps a tall door flat.
• Are the fixing screws included? Fixing screws are not supplied as standard unless agreed on the order; the drawing lists the specification we would ship so the screws match the holes in the plate and the hinge.

Sign-Off Checklist Before You Order This Hinge

• Door material confirmed as a panel material that can be bored to the drawing for this hinge.
• Cup recess bored to the drawing figure, not to a photograph, with the depth checked for the cup seating.
• Position confirmed per door against the three position drawings: full overlay, half overlay or inset, the case geometry choosing the drawing.
• Door height and mass confirmed against the hinge count, with an added hinge at mid height on tall doors.
• Hydraulic closing requirement confirmed in writing against the drawing, and felt on a sample in the buyer's own board, since the closing behaviour is the point of buying the soft close hinge.
• Adjustment travel confirmed on the sample, each screw turned through its travel so the door edge can be set after fitting.
• Plate fixings confirmed against the case construction, with the door plate holes and the case foot holes both on the drawing centres.
• Screw specification agreed separately, since fixings are not supplied as standard.
• Environment confirmed as dry or moderately humid; wet, hosed and coastal work is outside this finish.
• Sample worked through the full swing in the buyer's own board before the production order is cut, closing felt through the last degrees.

Ordering

Send the model number G-F877H with the quantity, the destination port and the carton marking you need. Samples are available before a production order so the hinge can be fixed and hung in your own board, the closing felt through the full swing and the position checked against your case, which is the fastest way for both sides to agree that the cup seating, the damper and the soft close closing are right. The drawing, the fixing sheet and whatever test documentation we hold for this hinge model are issued on request, and delivery and payment terms are agreed order by order on the proforma rather than assumed from a previous order.
