Cabinet hinge guide

How to identify a cabinet hinge

Start with the cabinet, not the logo. A clear view of the door edge, hinge cup and cabinet-side mounting is more useful than a partial stamped number.

Check the construction

Face-frame cabinets have a solid wood frame visible around the opening. Frameless cabinets use the cabinet side itself as the mounting surface. That distinction changes the hinge and plate options.

Then measure the cup

Most modern concealed hinges use a 35 mm cup in the back of the door. Record the cup diameter, the distance between screw holes, arm shape and overlay. Take a note of all markings, but do not treat a casting number as an orderable part number.

For a blank record to take to the cabinet, use the printable hinge field sheet.

Once you have those details, open the Cabinet Hinge Finder to record what you know and see where more evidence is needed.

Use the drawings as schematics, not drilling templates. Record what is actually installed before looking up a replacement. The same cup size or a familiar stamp does not prove that a new hinge will fit.

How to measure a closed door's overlayFront view of a closed cabinet door covering the left face frame. The overlay is the horizontal distance from the closed door edge to the opening edge, not the gap between doors.OVERLAYdoor edgeopening edgeclosed door
01 / Overlay. Close the door and mark its outside edge on the face frame. Open it; measure from that mark to the cabinet opening edge. Record the value and whether the door is overlay or inset.
Record the hinge cup and door screw patternBack-of-door schematic with a round cup and two screw centers. Measure the cup diameter and screw-center distance separately; 35 and 45 millimeters are examples for the verified COMPACT 33 configuration, not a universal pattern.CUP ØSCREW CENTERSback of door
02 / Cup and fixing. Measure the cup bore diameter and the distance from one door screw center to the other. Photograph screw-on versus press-in fixing. The verified COMPACT 33 screw-on case uses a 35 mm cup and 45 mm screw spacing; do not apply that pair to every hinge.
Distinguish the cabinet-side mounting plate number from a cup stampA two-hole cabinet-side plate with a plate-code location is shown separately from a circular door cup with a cup-stamp location. One-hole plates have different mounting geometry and must be recorded separately.PLATECODECUPSTAMPCABINET SIDEDOOR SIDEone-hole ≠ two-hole mounting
03 / Plate versus stamp. Read and photograph the complete cabinet-side plate code, hole count and location. Photograph cup/arm markings separately. A cup stamp may identify a family or component but not the installed orderable model.

Bench checklist

  1. Photograph the complete hinge, door cup, cabinet-side plate and every marking before removal.
  2. Record face-frame or frameless construction, and whether the closed door is overlay or inset.
  3. Mark the closed door edge; open the door and measure from that mark to the opening edge. Record the overlay with units.
  4. Measure cup diameter and door screw-center spacing; note screw-on or press-in fixing.
  5. Transcribe the full cabinet-side plate number and count its existing frame holes. Note any spacer or adapter.
  6. Compare the complete configuration with manufacturer instructions. If the plate, overlay or hole treatment is uncertain, stop at identification; do not order from the stamp alone.

Worked case / COMPACT 33

DIRECT only for verified two-hole cases: screw-on 33.3600 plus old edge plate 130.1100.23, 12.7 mm (1/2 in) overlay, face frame, 35 mm cup and 45 mm door screw centers maps to screw-on 38N355B.08. Blum says the existing cup and two frame-hole positions are reused; new #8 × 3/4-in truss-head frame screws are required. One-hole and press-in variants are outside this case.

Worked case / Grass 830

RETROFIT, not a drop-in swap: on a confirmed face-frame, two-piece TEC 830 installation with a 35 mm cup, cabinet-side plate 830-37 and verified 25.4 mm (1 in) overlay, Grass's chart lists TEC 864 self-close 04395-15. The cup bore and cabinet-frame holes can be reused, but new door-side screw holes are required. A bare 830 cup stamp does not establish this mapping.
