How it connects
The hinge door wing plate and clamp insert into the routed door edge slot; tightening the central clamp screw pinches the clamp plate against the wood inside the slot to lock the door in position while allowing lateral and vertical adjustment.
Male and female halves
Female slot/mortise routed into the cabinet door edge/back that receives the male clamping plate assembly of the hinge.

Variations

How to recognise it
A precision T-slot or rectangular kerf routed along the back edge of a cabinet door, with no screw holes penetrating all the way through, into which an oval or rectangular clamping bracket slides and tightens via a single machine screw.
Often confused with
| Confused with | How to tell them apart |
|---|---|
| 35 mm European concealed cup hinge mortise | European cup hinges require a circular 35 mm blind bore on the rear face, whereas demountable hinge door slots are routed linear slots/kerfs entering from the door edge. |
| Double-demountable frame slot | Double-demountable hinges have slots on both the door and the face frame; single-demountable hinges use the slot clamp only on the door wing while the frame wing attaches with standard surface screws. |

Good to know
Single-demountable hinges demount via a clamp only on the door side (the face-frame wing mounts conventionally with screws). Double-demountable hinges clamp into routed slots on both the door and the cabinet face frame.
