These tips are only for recessed concealed hinges as shown below
- This is a typical concealed hinge used on Kitchen, Bedroom Bathroom and built in cupboards.
- They come in two sizes 35mm dia and 26mm dia hole size.
- Most hinges used are the 35mm dia.
- 26mm dia hinges are sometimes used in small bathroom cabinets or budget carcasses.
Measuring Points from top
- The sample shows the measuring points for the top hinge hole.
- The same applies to the bottom hole.
- If you have four holes we would want the distance from the top for the upper two and the distance from the bottom for the lower two.
- If a new build with 4 hole you can enter "even" if the positions aren't critical.
- For centre holes we like the measurement from the top, You can enter "cen" or "centre".
Sample Dims of a typical door hole
- Almost all front fitting cabinet doors hinge holes are centred 22.5mm from the front with a 35mm dia hole
- The height distance vary between manufacturers and must be checked.
- If the hinge is 26mm dia the hole centre should be 18mm.
Door handing for hinge holes
- The door on the left is left hung.
- The door on the right is right hung.
- If you want a top hung door we like you to select the Top Box, ideally this is the only time a Top Box is selected.
- If you have doors of the same size and some are drilled and other are undrilled can you please order these as separate panels.
Examples of edge locations of 35mm hinge holes
- Most 35mm cup concealed hinges are centred 22.5mm from the edge.
- If you remove a hinge and you have 5mm between the door edge and hole it will be 22.5mm centres.
- Most 22.5mm hole positions are on 18mm thick carcasses.
- 15mm thick carcasses are more likely to be 20mm from the edge.
- You must not use the small screw holes as a guide, they vary from hinge to hinge.
- Hole position taken from the top or bottom of the doors as per the image above
You can order or quote without the final hinge positions and email later.
- Our standard positions are 85 top and bottom and any other holes evenly spread.
- You can add a short note to Customer ref. This is ideal if you have multiple doors with the same hinge holes,
- Or “even” if you just want to only add the top and bottom holes and let use work out the positions for the middle holes.
- Or you could enter “standard” and we will make the hinge holes 85mm top and bottom and the rest evenly spread.
- On angled doors the top hole if on the pointy side should be below 150mm from the top. This is to allow for access with a screw driver.
- The image below is a section from the Custom door page with the Customer Ref box ringed in red.
- Below is an image of part of the Custom Door page with the door notes check box highlighted with an arrow.
- If you tick the checkbox the panel note box appears.
- You would enter non standard from the edge hole positions
- Or 26mm hinges here, 26mm holes are normally centred 18mm from the edge. You can check by removing a hinge and you should have 5mm between the edge of the door and the edge of the hole.
- Also you can request standard or even holes from the top and bottom.
- Most hinge centre holes are 22.5mm from the edge, but this is not always the case and we would recommend removing one hinge and checking that the distance from the edge of the hole to the edge of the door is 5mm.
Door hinge holes locations from a carcass
Working out the top hinge hole locations from a carcass
You need to know the thickness of the carcass, these are mostly 18 mm thick or 15 mm thick.
Doors are usually shorter than the carcass by 2.5 mm at the top and another 2.5 mm at the bottom. This space is for clearance of worktops etc.
If "A" carcass thickness is 18 mm add 31.5 to
"B" Upper 5 mm hole centre to under cabinet
If "A" carcass thickness is 15 mm add 28.5 to
"B" Upper 5 mm hole centre to under cabinet
"C" should be 32 mm apart and 37 mm in from the front
"D" 2.5 mm is the door height from the top of the cabinet this allows clearance for worktops etc.
You normally have a 2.5 mm gap at the bottom as well.
Some cabinets have the holes on the same level.
With these you just Add dimension "B" to the carcass thickness and subtract 2.5 mm.
Some of the hinges with this configuration of hinge plate may have little or no vertical adjustment.
