Polished 45 Degree Corner Cup Hinge G-F728

G-F728 Polished 45 Degree Corner Cup Hinge In Six Photographed Positions

This listing is written from the six photographs on this page, and what they show is a 45 degree corner cup hinge of the cabinet hinge range in a polished bright finish: the folded three quarter view where the round cup, the base plate, the barrel knuckle and the cranked arm all read at once, the folded view from the opposite side where the hinge runs the other way, the vertical side view where the profile is the whole of the frame, the open front view where the cup opens to the camera and the base plate sits square, and the open side view where the cranked arm swings out on its long positioning pin. Two honesty points govern the whole page. First, this set carries no drawing frame, so no dimension figure is stated anywhere on it: the cup figure, the plate figure and the body figure are drawing facts that we issue with the quotation, and the page says so instead of guessing them. Second, no damper is readable as a part in any of the six frames, so the hinge is carried as a free swinging hinge, and the closing - the lack of damping on this member - is the fact confirmed on the sample rather than the page.

The frames prove the structure directly: a round cup that seats into a bored recess in the door, a base plate that screws the hinge to the case side, a barrel knuckle that carries the swing, and a cranked arm that rides the cup at the 45 degree angle. That is the cup hinge form in its corner expression, and the 45 degree figure on the hinge is what places the rotation axis off the face of the door so that the leaf clears the adjacent panel of the case through the whole arc of the swing. A 45 degree hinge is the cabinet hinge member for the door that turns a corner or meets an angled return, and the cranked arm is the part that makes that possible.

The 45 Degree, As The Corner Door Asks For It

A 45 degree hinge of this range exists for the door that swings into a corner or meets an angled panel. Where a square cabinet door runs clear of the room and a 90 degree hinge of the range is the call, there are doors that turn a corner, a bay window, a diagonal return, or the angled face of a corner unit, and the 45 degree hinge is the cabinet hinge member that carries the leaf on the cranked axis so it clears the adjacent panel through the swing. The vertical side frame on this page is where the cranked geometry reads: the arm leaves the knuckle at the angle the hinge was cut for, and the cup sits where the drilling template puts it. The buyers who reach for a 45 degree hinge are the ones whose layout already answers the question: the corner cabinet of a run that turns the room, the diagonal door of a bay, the angled appliance garage, and the blind corner where a square door simply cannot reach. The angle is the feature, and the frames show the hinge as the part that carries it.

Because the 45 degree figure is in the cranked arm and not in the room, a case built for a square door is not a case ready for this hinge without the layout being rechecked: the leaf of the door, the gap of the case and the swing arc all answer to the 45 degree figure. That is why the model number carries the angle the way it does, and why the comparison between this 45 degree corner hinge and the 90 degree member of the range starts with the layout drawing rather than with the photograph. A square door on a 45 degree hinge is a door that meets the cranked arm before it clears the case, and the layout is where the two are told apart.

What The Photographs In This Listing Prove

Every structural claim on this page can be pointed at in one of the six frames: the cup with its base plate in the folded three quarter view, the cup opening to the camera in the open front view, the profile of the whole body in the vertical side view, the cranked arm swung out on its long positioning pin in the open side view, and the hinge from the opposite side in the second folded view. What the frames do not prove is any figure: there is no drawing in this set, so the cup diameter, the base plate spacing and the body length are not numbers on this page. They come from the hinge drawing that we send with the quotation, and the drilling is done against that drawing rather than against the photographs.

The staged set also omits, on purpose, the remaining frames of the folder that repeat the same six camera positions from nearer or farther, and the multi piece composite frame, which the page keeps out of the gallery so that each of the six positions on the page is a distinct view rather than a repeat of one. What remains is six different views, and each of the six views is used once in the image gallery on this page.

How The 45 Degree Cup Hinge Is Built

The open side frame is the clearest frame for reading a 45 degree hinge, and the frame on this page is that frame: the cup with its base plate, the barrel knuckle, and the cranked arm swung out on its long positioning pin. Three things about this construction are worth a buyer knowing before the drawing arrives. First, the cup is the member that seats into the bored recess of the door, and the base plate is what screws the hinge to the case side, so the drilling answers to the drawing and the plate answers to the drilling. Second, the cranked arm is what places the pivot off the face of the door, so the leaf clears the adjacent panel of the case through the whole arc of the swing, which is the difference between a 45 degree hinge and a square door hinge. Third, the long positioning pin is the reference of the arm that the fitter works when the hinge is aligned at the door strip, and the pin is what the frame on this page shows swung out to the side.

• Round cup that seats into a bored recess in the door, the cup hinge form shown in the folded three quarter view.
• Base plate on the cup, the member that screws the hinge to the case side of the cabinet.
• Barrel knuckle as the pivot, carrying the swing of the door leaf.
• Cranked arm that places the pivot off the face for the 45 degree corner of the door.
• Long positioning pin on the arm, shown swung out in the open side view.
• Polished bright finish as the six frames show it, even across the cup, the knuckle and the arm.
• Free swing closing, no damper part readable in any frame, the damped 45 degree member listed under its own model number.
• No drawing in this set, so no dimension figure on this page; the figures come with the quotation.

Free Swing, As The Frames Show It

No damper is visible as a part in any of the six frames, so the page carries the closing the honest way: this 45 degree hinge is a free swinging hinge. The door opens on the knuckle and closes by its own weight of the leaf and the hand of the person at the door, not by a damping mechanism. The same 45 degree corner geometry range is also offered as a damped and a soft closing member under its own model number, so a buyer who wants the quiet landing on this exact shape says so on the order and the damped member is the specification; the free swinging member of the frames is the call for the door where the closing is not the question. The sample is where the swing is worked and the closing is confirmed, and the closing is the fact that comes back from that test rather than from the page.

Polished Finish, As The Frames Show It

The six frames show a polished bright finish across the cup, the base plate, the knuckle and the arm, and that is the finish fact the page carries, because the finish is what a photograph can certify. The alloy under the finish is a drawing fact: the same 45 degree corner geometry is also listed by us in a nickel plated finish under the model number F728, and the two members are the same geometry in two finishes, so a buyer choosing between them is choosing the finish and the environment, not the shape. For the polished member the honest case is the one every buyer of a polished hinge knows: the finish is an interior one, the hinge is made for the dry cabinet and the dry kitchen rather than the hosed surface, and the environment it is specified for is the one the frames show it in. Where the environment is wet, the plated member is the call, and the drawing lists the finish of each member so the order states it rather than assumes it.

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

A 45 degree corner cup hinge of this shape belongs on the door that swings into a corner or meets an angled panel: the corner cabinet of a run that turns the room, the diagonal door of a bay, the blind corner where a square door cannot reach, and the angled appliance garage that turns 45 degrees from the face of the case. The open side frame on this page is the fastest way to read what the cranked arm is doing in a real case: the cup in its recess, the arm on the knuckle, the door held on the 45 degree axis the way the hinge was cut. It is the wrong call for a square door, because the 45 degree figure is in the cranked arm and a square door on a 45 degree hinge is a door that meets the arm before it clears the case. It is the wrong call for a door that is too heavy for the cup figure the drawing states, because the cup and the plate carry the leaf and the figure on the drawing is where the weight question is answered, and it is the wrong call for a wet environment, because the polished finish of the frames is an interior finish.

How This Hinge Sits In Our Range

Within our own hinge range, a buyer choosing a corner or angled door hinge is choosing between the angle, the closing and the finish, in that order. The angle sets the layout: the 45 degree hinge is the cabinet hinge member for the door that turns a corner, and the 90 degree member of the range is the one for the door that stops at the wall. The closing sets the behaviour: the free swinging member of the frames is the hinge for the door where the closing is not the question, and the damped member of the same 45 degree geometry is the hinge for the quiet landing. The finish sets the environment: the polished member of the frames is the interior call, and the nickel plated member of the same geometry is the call for the harder service. A buyer comparing this hinge against our other corner hinges should compare the angle first, because the 45 degree figure is in the cranked arm and the layout is where it shows up.

It also sits against the other corner and angled members we supply, and the honest position is the one on the specification table: the cup form and the cranked arm are the comparison that matters, the finish is what the frames show, the closing is what the frames state by the absence of a damper, and the cup figure is what the drawing carries rather than what the page guesses. A buyer who needs the same 45 degree angle in a different closing or the same closing in a different finish should say so on the order, because the line is built around those choices and the drawing is what ties the choice to the part number.

Specification Summary

How Each Hinge Batch Is Checked Before Packing

Every hinge batch is sampled on four points before packing. Assembly: the cup is checked to seat true on the knuckle, the base plate is checked to sit square to the cup rather than twisted, the cranked arm is checked to run true on the 45 degree axis and the long positioning pin is checked to sit in its seat rather than proud. Appearance: the polished surface is checked for handling marks and any scratch that runs across the cup or the arm, which is the part that shows first in a lit kitchen, and the finish is checked to run even across the knuckle and the base plate. Function: each sampled hinge is worked through its full swing by hand, opened to the 45 degree axis and closed on the free swing, so a binding knuckle or a swing that runs short shows up before the carton closes, and the cranked arm is checked to run clear of the case through the whole arc. 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 angle, the closing and the finish 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

• 45 degree hinge: a corner and angled door hinge whose cranked arm places the pivot off the face so the leaf clears the adjacent panel, the member of the range for the door that turns 45 degrees.
• Cup hinge: a hinge whose cup seats into a bored recess in the door and whose base plate screws to the case side, the form shown in the six frames.
• Cabinet hinge: the application of this part, the leaf of a cabinet, kitchen run, corner unit or vanity that swings on the cup and the knuckle.
• Corner hinge: the 45 degree application, the angled door of a bay, the diagonal return and the blind corner where a square door cannot reach.
• Cranked arm: the member that carries the pivot off the face of the door for the corner, the arm shown swung out in the open side view.
• Free swing: the closing of this member, no damper part readable in any frame, the door closing by the weight of the leaf rather than by damping.
• Positioning pin: the long pin of the cranked arm, the reference the fitter works when the hinge is aligned at the door strip of the case.
• Drawing: the document that turns a hinge photograph into a hinge specification; without it the cup, plate and body figures are not checked, and we send it with the quotation.

The Parts Of The Hinge, Named As The Frames Show Them

• Cup: the round member that seats into the bored recess of the door; the cup is where the hinge meets the leaf, and the folded three quarter view is the frame where the cup reads at its best.
• Base plate: the member that screws the hinge to the case side; the plate carries the fixing, and the open front view is the frame where the plate sits square to the camera.
• Knuckle: the barrel pivot that carries the swing of the door leaf; the vertical side view is the frame where the knuckle stands up out of the cup.
• Cranked arm: the member that runs off the knuckle toward the door at the 45 degree angle; the arm carries the leaf through the swing, and the open side view shows the cranked arm swung out on its pin.
• Positioning pin: the long pin of the cranked arm; the pin is the reference the fitter works when the hinge is aligned at the door strip of the case, and it is what the open side view shows to the side.
• Swing: the arc the door works on the cranked axis from the closed face of the door to the corner of the case; the swing is carried by the knuckle, and the sample is where the swing is worked through its full arc.
• 45 degree axis: the figure where the cranked arm places the pivot for the corner; the angle is in the arm rather than in the room, and the door works on that axis through the swing.
• Free swing: the closing the member carries by the absence of a damper; the closing is by the weight of the leaf, the frames show the body rather than a damping mechanism, and the sample is where the closing is confirmed.
• Polished finish: the finish the frames show across the hinge, even on the cup and the arm; the finish is the photograph fact, and the drawing is where the alloy under the finish is stated.
• Drilling: the boring of the cup recess in the door and the plate holes in the case that the hinge answers to; the drilling is cut against the drawing, and the hinge is checked in its recess before the plate is screwed home.

Common Hinge Faults And What They Actually Mean

A door that drifts open on a cup hinge is almost always a fixing problem rather than a hinge problem. The hinge is the strongest part of that joint; the recess and the plate behind it are not. In chipboard and MDF the holding power depends on the cup boring of the hinge and the plate screws of the hinge, and a hinge that has been fitted and refitted while a fitter chases the line of the hinge loses grip, which shows up later as the door of the hinge sagging at the strip while the hinge itself is still sound. On a 45 degree hinge of the hinge the drift can look like the door not reaching the corner of the hinge, and the answer is still the fixing of the hinge and the boring of the hinge, not a heavier hinge.

A door that will not reach its corner is usually a layout question before anything else: the leaf of the hinge, the case of the hinge and the cranked axis have to be built to the 45 degree figure of the hinge, and a door of the hinge that meets the cranked arm of the hinge early is the classic sign of a leaf cut wide or a case built narrow. The frame on this page shows the hinge at the angle the cranked arm of the hinge was cut for, and the check is to work the door against the hinge before the plate of the hinge is screwed home, because correcting a door that was never cut to the angle of the hinge after the boring of the hinge is done costs more than the hinge. A swing that feels tight on the cranked arm of the hinge is a different question: it is the alignment of the hinge against the case, it is checked on the sample of the hinge in the buyer's own door, and it is the fault a fitter notices before a buyer does.

The faults that actually do come from the hinge are the cup of the hinge, the knuckle of the hinge and the cranked arm of the hinge: a cup bored crooked in the door of the hinge, a knuckle that seats cross loaded through the swing of the hinge, a cranked arm that runs proud of the case, and plate screws 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 polished 45 degree hinge working is the same as the way to keep any hinge working, which is to fix the hinge true the first time with the cup of the hinge in its recess and the plate of the hinge square to the case.

Questions Buyers Ask About This Hinge

• Is this hinge 45 degrees or 90 degrees? The hinge is the 45 degree member of the range, cut for the door that turns a corner or meets an angled panel. The 90 degree hinge of the range is the member for the door that stops at a square wall, and the angle of the hinge is in the cranked arm, so the two are told apart by the layout of the door rather than by the finish of the hinge.
• Why would I want a 45 degree hinge and not a square door hinge? Because the door has to turn. A 45 degree hinge is for the corner cabinet of a run, the diagonal door of a bay, the blind corner or the angled appliance garage, and the cranked arm of the hinge is what clears the leaf of the hinge off the adjacent panel of the case. A square door that runs clear of the room is the member of the range for that door, and the layout of the hinge is where the two are told apart.
• Is this hinge soft close? No damper is readable as a part in any frame of the hinge, so the page carries the closing of the hinge as free swing: the door of the hinge closes by the weight of the leaf. The damped and soft closing member of the same 45 degree geometry is listed under its own model number, so a buyer who wants the quiet landing on this shape of the hinge says so on the order and that damped member of the hinge is the specification.
• What is the difference between this G-F728 and the F728 you list in nickel plated finish? The same 45 degree corner geometry of the range in two finishes: this listing is the polished member of the hinge shown in the six frames, and the F728 is the nickel plated member of the same hinge specified for the harder service. The 45 degree angle of the hinge, the cranked arm of the hinge and the cup form of the hinge are the geometry of the hinge; the finish of the hinge is the choice, and the drawing of the hinge lists the finish of each member.
• What cup size is this hinge? The cup figure of the hinge is a drawing fact and this photograph set of the hinge carries no drawing, so the page of the hinge does not state the figure rather than guess it. The drawing of the hinge comes with the quotation, and the boring of the hinge is done against it.
• Do the fixing screws come with the hinge? The frames do not show screws staged with the hinge, so the copy carries it that way: the fixing screws of the hinge are agreed on the order, the gauge set to the board and the cup boring of the hinge, and the drawing of the hinge lists the specification we would ship so the screws match the holes of the hinge and the door.
• How many do I need on a door? The count follows the length and the mass of the leaf, the usual working rule being one hinge per standard door height and a second hinge where the leaf runs long or carries the weight of a run. The figures that govern the count of the hinge come from the drawing of the hinge and the sample worked in the buyer's own door, not from the photograph of the hinge.
• Will the polished finish of this hinge hold up in a kitchen? In a dry kitchen, yes, and the polished finish of the frames is the interior call the hinge is built for. Where the surface is hosed or the environment is wet, the nickel plated member of the same hinge geometry is the specification, and the drawing lists the finish of the hinge so the order states it rather than assumes it.
• What does the cranked arm of this hinge do for me? It places the pivot of the hinge off the face of the door, so the leaf of the hinge clears the adjacent panel of the case through the whole arc of the swing of the hinge. On a square door hinge the pivot of the hinge is on the face and the door runs clear of the room; on this 45 degree hinge the cranked arm of the hinge carries the leaf around the corner, and the open side view of the hinge is the frame that shows the arm of the hinge swung out on its positioning pin.
• Can I use this hinge on a door bored for a different cup figure? No, and the cup of the hinge is the part that answers: the hinge seats on the recess the door was bored for, and a door bored to another figure is not a door ready for this hinge without the boring of the hinge being redone to the drawing of the hinge. The figure is on the drawing we send with the quotation, and the hinge is checked in its recess before the plate of the hinge is fixed.

Sign-Off Checklist Before You Order This Hinge

Ordering

Send the model number G-F728 with the quantity, the destination port and the carton marking you need. Samples are available before a production order so the swing of the hinge can be worked in your own door, the free swing closing of the hinge confirmed against the leaf, and the cranked arm of the hinge checked at the door strip of the case, which is the fastest way for both sides to agree that the cup, the knuckle and the plate of the hinge 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.
