Blind Corner Geometry and a Self-Close Spring in One Hinge

The Hettich Intermat blind corner hinge brings overlay doors around the restricted angle of a blind corner cabinet, with a self-close spring that pulls the door shut automatically on both face-frame and frameless boxes.

Key Features

• Blind corner geometry restricts the swing to 95 degrees so the door clears the adjacent cabinet without collision.
• Self-close spring pulls the door shut from a few degrees open, no push needed.
• Overlay arm positions the door over the cabinet side or face-frame edge at a standard overlay.
• Dowel mount cup presses directly into pre-bored 8mm dowel holes for fast, screw-free door-side installation in CNC and production environments.
• Works on face-frame and frameless cabinets when paired with the correct Hettich base plate, sold separately.
• Fits doors 15 to 28mm thick, a wider window than standard hinges, covering everything from thin overlay panels to thicker solid-wood doors.

Built for the Blind Corner Problem

A blind corner cabinet sits at a 90-degree corner where one cabinet partially hides behind the other. The challenge is simple: the door needs to swing open without striking the adjacent cabinet face. This hinge solves that by limiting the opening arc to 95 degrees, which is exactly the clearance a properly set blind corner door needs. That restricted angle is not a shortcoming; it is the engineering that makes the application work. The 35mm cup bores into the door, and the hinge arm connects to a Hettich base plate mounted to the cabinet side or stile. The plate is sold separately and must be a Hettich-compatible plate matched to the cabinet construction.

Steel Construction with a Production-Ready Mount

The hinge is steel with a nickel finish. The dowel mount sets it apart on the installation side: instead of driving cup screws into the door, the pre-mounted dowels press into 8mm bored holes in the door face, the same holes a CNC machine lays out automatically in a production run. That connection locks the cup in position without hardware fiddling, which keeps the line moving when you are hanging cabinets at volume. Depth and side adjustment come from the arm after the plate is mounted, letting you dial in the reveal once everything is on the box.

Who Reaches for This Hinge

Cabinet shops running CNC-bored doors will find the dowel mount fits naturally into their workflow. Contractors installing production cabinets on site benefit from the same thing: no cup screws to drive, just press and hang. The face-frame and frameless compatibility means the same hinge covers both box types on a mixed job. For a corner run where the self-close spring is enough and a cushioned close is not required, this is the practical pick. If a damped, quiet close matters more than the spring pull, look at the Hettich Intermat soft-close variant in this family instead.

Corner Doors That Clear and Close on Their Own

Specify this hinge when the job calls for overlay doors on blind corner cabinets, a production-ready dowel mount, and a self-close spring that handles the rest.
