Blind Corner Hinge For Inset Doors on Face-Frame and Frameless Cabinets

The Hettich Intermat is a concealed blind corner hinge designed for inset doors where the cabinet sits adjacent to a wall or another run, with self-close and a 95 degree opening angle that lets the door clear the neighboring cabinet without collision.

Key Features

• 95 degree opening angle is the geometry that allows a blind corner door to swing clear of the adjacent cabinet without binding.
• Inset overlay sets the door flush inside the cabinet opening, with an even reveal on all sides.
• Self-close spring pulls the door shut automatically over the last few degrees of travel.
• Dowel mount presses the cup into pre-bored 8mm dowel holes in the door for fast, screw-free door-side installation.
• Works on both face-frame and frameless cabinets when paired with a matching Hettich base plate, sold separately.
• Three-way adjustment covers depth and side movement to dial in the reveal after the cabinet is set.

Built for the Blind Corner Problem

A blind corner cabinet sits at the end of a run or in an inside corner where the door, if it swung fully open, would strike the adjacent cabinet face. The 95 degree opening angle on this hinge is not a shortcoming — it is the designed limit that lets the door stop before that collision point. Pair that geometry with inset placement, where the door sits inside the opening rather than over it, and you have a hinge built for a specific, demanding condition that a standard 110 degree hinge cannot serve correctly.

The 35mm cup bores into the back of the door and the arm connects to a Hettich base plate on the cabinet, ordered separately. Plates are Hettich-specific, so use a plate from the Intermat or compatible Hettich range rather than a plate from another brand.

Steel Construction and a Door Thickness Range Built for Real Work

The hinge is plated steel in a Nickel finish. It accommodates doors from 15mm to 28mm thick, a wider window than most standard concealed hinges, which suits the heavier or thicker panels sometimes used in corner cabinet construction. Depth adjustment of plus 3mm and minus 2mm, along with plus or minus 2mm of side adjustment, gives the installer room to true up the door after mounting without pulling the hinge.

Who Reaches for This Hinge

Cabinet shops building face-frame runs that terminate at a wall, designers specifying frameless corner arrangements, and remodelers replacing a blind corner hinge that has worn out all benefit from the specific geometry here. This is not an everyday full-overlay hinge for standard doors — it is a position-specific part for a corner condition that calls for a restricted swing. For inset doors at standard cabinet positions, a 110 degree inset hinge is the better fit. For overlay doors at a blind corner, this Intermat series offers overlay variants as well.

Common Questions

The Right Hinge for a Corner That Demands Precision

Specify this Hettich Intermat when the layout puts an inset door next to a wall or adjacent cabinet and a full-swing hinge simply will not fit the geometry.
