Stainless Steel Cabinet Hinge Repair Plate Kit G-K4192

The G-K4192 Hinge Repair Plate Kit In Eight Photographed Positions

Eight frames are used for this repair plate kit and the first one is the kit as it arrives: four stainless steel plates and a row of screws on a white ground. That is the frame to start from, because a repair plate is bought as a set and the set is what decides whether a stripped hinge hole can be saved. The plates in the first frame are not four copies of one shape. There is a U shaped plate, two square plates and one narrow rectangular plate, and each shape answers a different damaged fixing on a cabinet door.

A hinge repair plate does one job in a workshop: it puts sound material back where a hinge screw has torn out. When a cabinet door hinge pulls loose, the timber around the screw is usually gone, and driving a larger screw into the same hole only delays the failure. A stainless plate bridges that damaged area, spreads the load over a wider face and gives the hinge a fresh set of holes to be fixed into. That is why the plates here carry a large central bore as well as screw holes: the bore clears the hinge cup and the arm, and the screw holes are drilled outside the damaged zone.

The frames on this page were shot as one set, square at 750 pixels and exported a second time slightly taller. The second export is the same camera positions, not a second shoot, so the folder holds one set of views rather than two. The six gallery frames were chosen to show the kit, the three plate shapes with their marked sizes and the way the plates sit together when they are laid out for a job.

Four Plates, One Screw Pack

The count matters as much as the shapes. A door that has lost its hinge fixings usually needs more than one repair plate: one plate on the cabinet side and one on the door side, because a hinge pulls on both. The two square plates are the pair for that job, and the reason there are two rather than one is the fixing centres. One square plate carries its holes 75 mm apart and the other 74 mm apart, so between them they cover the two common patterns of a European style hinge without drilling a new hole in the plate. A buyer who checks the hinge on the door against those two figures knows which square plate goes where before the parcel is opened.

The U shaped plate and the narrow rectangular plate are the shapes for the tighter jobs. The notch in the U plate lets it slide past the hinge cup or past a rail, so the plate can be fixed on both sides of the damaged area rather than only on one. The rectangular plate is the narrow one, 44 mm across, and it is the one that fits where a square plate would overhang the door edge or foul the carcass. Between the four shapes there is a plate for a full door face, a plate for a door edge and a plate for a corner where the damaged fixing sits close to two edges.

What The 35 mm Bore Is For

The second frame is the square repair plate squared to the camera, with its sizes marked, and the figure to read first is the bore. A 35 mm bore is the diameter of a European style hinge cup, which is the round recess bored into the back of a cabinet door to take a concealed hinge. That is not a coincidence: the plate is made to lie flat over the damaged area with the hinge cup passing through the bore, so the hinge can be refitted at the height it was originally set at instead of being moved up or down the door.

This is the difference between a repair plate and a patch. A plain patch would cover the damaged screw holes and force the hinge to be relocated, which means new holes in the door and a hinge that no longer lines up with its mounting plate on the carcass. A repair plate with a 35 mm bore leaves the cup where it is. The hinge drops back into its own recess, the plate takes the screws that the timber can no longer hold, and the door goes back on the cabinet with the gap it had before the hinge pulled out.

The second frame also shows why the fixing holes are arranged the way they are. Around the bore there is a ring of small pilot holes and, outside that, the corner holes that take the screws. The corner holes are far enough from the bore that they land in sound material beyond the torn area, which is the whole purpose of the plate. The small pilot holes let the same plate be used with a hinge whose fixing pattern is rotated, so one plate covers a hinge fixed at one position and the same hinge fixed a quarter turn round.

The two square plates in the kit differ in that hole pattern rather than in outline. Both are 90 mm by 90 mm and both carry a 35 mm bore; one is drilled at 75 mm centres with the denser pilot pattern, the other at 74 mm centres with fewer pilots. Held against a hinge, the difference is visible in a second, and it is the reason the kit ships as a pair instead of asking the buyer to order a pattern. Where a door has been repaired once already and the fixing has moved, the plate with the denser pilot pattern is the one that gives a fresh hole without touching the old one.

The U Plate And The Narrow Plate

The fourth frame is the U shaped repair plate on its own, and it is the shape most people picture when they ask for a hinge repair plate. The notch is 78 mm wide across a 90 mm plate, which leaves a narrow leg of material at either side of the notch, and the four corner holes sit outside the notch line. That geometry is what makes the U plate useful at a door edge: the notch straddles the hinge cup or the edge of the damaged area, the two legs of the plate land on sound material on either side, and the screws pull the plate down flat instead of bowing it over the hole.

The narrow rectangular plate is the same idea for a different constraint. At 90 mm by 44 mm it is about half the depth of the square plate, so it fits between a hinge and the edge of a door, or under a hinge on a cabinet side where a square plate would foul the carcass. It carries the same 35 mm bore and the same 75 mm fixing centres as the square plate, so a hinge that fits one fits the other; what changes is how much plate there is around the hinge. Where the damaged area is small and the surrounding panel is sound, the narrow plate is enough. Where the timber has gone over a wider circle, the square plate is the one to use.

Laid out together as the first frame does, the four plates read as a system rather than as four separate fittings: two square plates for a full face repair on the door and on the carcass, a U plate for a fixing at an edge or around a cup, and a narrow plate for a tight return. A workshop that keeps the kit on the shelf stops improvising repairs out of offcuts, and a repair made with a plate of this shape is one that can be undone and redone without the door being replaced.

Stainless Steel, And Why It Matters Here

Every frame in this batch marks the material as stainless steel, and on a repair plate the material is doing more work than it looks. A repair plate stays in the door for the life of the cabinet, under a hinge, in a place nobody inspects. A plated steel plate would be fine until the plating is broken at a screw hole, and a screw hole is exactly where plating breaks; once the steel underneath is exposed, a kitchen or bathroom door gives it moisture and the plate rusts from the inside of the hole outwards. A stainless plate has no coating to break, so the edge of a screw hole stays stainless and the repair does not become the next failure.

The finish on these plates is brushed rather than polished, which the frames show plainly. That is the practical finish for a repair plate for two reasons. A brushed face does not show the scratches that a screwdriver leaves when a fixing slips, and it grips a hinge cup slightly better than a mirror face, so a hinge that is refitted over a plate is less likely to creep. A polished plate looks better in a photograph and worse after a year behind a door, which is why the plates here are left as brushed stainless.

Thickness is the third material point and the one that decides whether a repair plate works. The plate has to be thin enough that the door still closes against the carcass with the hinge mounted on top of it, and stiff enough that the screw heads do not dish it into the damaged area. Sheet stainless of this gauge does both: it is thin enough to sit under a hinge cup without packing the door out, and it is stiff enough that the load from the hinge is carried out to the corner screws rather than concentrated at the bore. A plate cut from thin mild steel would bend at the first door slam and the repair would be back where it started.

Fitting A Repair Plate Over A Stripped Hole

The sequence below is the one the frames support, and it is the sequence that keeps the hinge in its original position. It is written for a cabinet door whose hinge screws have pulled out, which is the job a hinge repair plate is made for.

• Take the door off and put the hinge to one side; a repair plate is fitted with the door flat, not hanging.
• Clean the damaged area back to sound material and take out any loose fibres, so the plate lands on something solid rather than on crumble.
• Offer the plate up with the 35 mm bore over the hinge cup recess, and check that the corner holes fall outside the torn area.
• Mark the corner holes through the plate, then drill pilot holes sized to the screws in the pack rather than to the old screws.
• Fix the plate down at the corners first, leaving the screws just nipped, so the plate can still be moved a fraction.
• Set the hinge back into its cup through the bore, fix it to the plate, then tighten the plate screws while the hinge holds the plate in line.
• Hang the door and check the gap at the top and the bottom before the final tighten; the plate is what gives the hinge something to hold, not a way to change the door height.
• Run the door through its whole opening once, listening for a knock, then re-check the plate screws after a week of use.

Two of those steps are where repairs fail. The first is skipping the pilot holes and driving the screws straight into the plate: a stainless plate will not let a screw cut its own thread, and forcing one rounds the head and marks the face. The second is tightening the plate before the hinge is set. If the plate is pulled down hard first, the hinge cup can end up sitting a fraction high in the bore, and the door then rubs at the bottom even though the hinge is sound. Set the hinge, then tighten the plate, and the two line up.

The Names This Kit Sells Under

A kit of this kind is asked for under several names and the three used on this page are the ones with real search behind them. It is a hinge repair plate, because that is the part a joiner asks for when a hinge has torn out of a door and the phrase a fitter types when a cupboard door has dropped. It is a cabinet hinge repair plate kit, because what arrives is a set of plates and screws rather than a single plate, and because the job is a kitchen or bedroom cabinet rather than a site door. It is a euro hinge repair plate, because the 35 mm bore and the 75 mm fixing centres are the European cup hinge pattern, and a fitter searching for that name has a concealed hinge in mind.

It is worth saying what this kit is not, because all three names get used loosely. It is not a hinge: nothing in the frames moves, and a plate cannot replace a broken hinge, only give a sound hinge something to be fixed to. It is not a mounting plate or a hinge plate of the kind that clips onto a cabinet side to carry a concealed hinge; that part is a pressed bracket with a clip, and the plates here are flat sheets with a bore. It is not a door stiffener or a mending plate for timber joints, although the shapes look similar: the 35 mm bore and the fixing centres are what make these a hinge repair plate rather than a general repair plate.

There is one more name worth knowing because it is what the part is called on a quotation in some markets: a hinge fixing plate, or a cupboard door hinge repair bracket. They describe the same sheet. If a buyer sends an enquiry using one of those names and a photograph of a stripped hinge hole, the plate in these frames is the answer, and the sizes marked on the frames are what should be checked against the door before the order is placed.

Questions A Buyer Asks About This Kit

The questions below are the ones that come back most often on a repair plate kit, and each answer points at a frame or a plate in the set.

• What is in the kit? Four stainless steel plates and a row of screws, as the first frame lays them out.
• What are the plate sizes? Two square plates 90 mm by 90 mm, one U plate 90 mm by 50 mm and one rectangular plate 90 mm by 44 mm.
• What is the bore for? 35 mm, which is the European hinge cup diameter, so the hinge drops back into its own recess.
• What are the fixing centres? 75 mm on one square plate and on the rectangular plate, 74 mm on the second square plate.
• Which plate do I use on a door? The square plate for a full face repair, the narrow plate where a square plate would overhang, and the U plate at an edge or around a cup.
• Is it stainless? Yes, the material is marked stainless steel on the frames, with a brushed face and no coating.
• Will it hold a hinge that has torn out completely? It gives the hinge fresh holes in sound material around the damage; how much damage there is decides which plate to use.
• Does it change the door height? No, the hinge stays in its own cup through the bore, so the door goes back at the height it was set at.
• Can the plates be used on metal doors? They are made for timber panels; on a metal door the plate still needs sound material behind it to take the screws.
• Can I order one plate on its own? Ask with the model number; the kit is quoted as a set, and single shapes are quoted separately on request.

Checks Before A Plate Goes On

A repair plate is a small part in an awkward place, and the checks below are the ones that catch a return before the parcel leaves. Each is a check on the kit rather than on the cabinet.

• Bore measured against the hinge cup, so the plate sits down over the recess rather than on top of it.
• Fixing centres checked against the hinge on the door, so the right one of the two square plates is used.
• Corner holes checked for sound material beyond the torn area, since a plate screwed into crumble holds nothing.
• Plate laid on the panel dry and pressed at the bore, to confirm it does not dish before any screw is driven.
• Screw length checked against plate plus panel, so a screw does not break through the door face.
• Plate edges checked for burrs, because a burr at the bore lifts the hinge cup and shows as a door that rubs.
• Notch of the U plate offered over the obstruction, so the plate does not need to be forced into place.
• Kit counted against the list before packing: two square, one U, one rectangular and the screw row.

Who Supplies This Repair Plate Kit

This stainless steel hinge repair plate kit 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, corner brackets and the connecting plates that go with them. The company works to export orders: quantity, plate sizes, screw specification, packing, carton marking and shipping documents are agreed before production rather than after it, and the specification written on the order is the specification the press and the laser work from. The gauge of the sheet, the bore size, the fixing centres and the finish are all part of that specification.

Ordering

Send the model number G-K4192 with the number of kits you need, the plate shapes you want repeated if a job uses more of one than the other, the screw specification and the destination port, and confirm the bore and the fixing centres against the drawing at the same time. Samples are available before a production order, so a plate can be offered up to a real hinge cup and a real damaged door, which is the fastest way for both sides to agree that the bore clears the cup and that the corner holes land in sound material. The drawing, the packing list and whatever test documentation we hold for G-K4192 are issued on request, and delivery and payment terms are agreed order by order on the proforma rather than assumed from a previous order.
