Blind Corner Hinge for Inset Doors on Frame and Frameless Cabinets

The Grass Tiomos Impresso is a self-close concealed blind corner hinge built for inset doors on face-frame and frameless cabinets, where the adjacent cabinet wall limits how far the door can swing and precise clearance control is the job.

Key Features

• Blind corner geometry limits the opening arc so the door clears the adjacent cabinet wall without collision.
• Inset overlay positions the door flush inside the cabinet opening with an even reveal on all sides.
• Self-close spring pulls the door shut over the last few degrees of travel.
• Toolless snap-on arm connects to the base plate without a screwdriver, speeding door hanging and removal.
• Three-way adjustment moves the door up to 3mm in height, side, and depth after mounting.
• 42/45mm dual bore pattern suits both Grass boring and standard 45mm cabinet setups.

What the Blind Corner Geometry Actually Does

A standard hinge in a blind corner application swings the door wide enough to strike the adjoining cabinet. The Tiomos Impresso blind corner hinge is engineered with a restricted opening arc that stops the door before it reaches the adjacent wall, so the corner layout works without adding a bumper or reworking the cabinet run. The 110-degree angle is the controlled result of that geometry, not a limitation. The inset arm positions the door inside the opening rather than over the face, which keeps the reveal consistent with any other inset doors in the same run. The 35mm cup bores into the door at 12.6mm depth, and the arm connects to a Grass base plate on the cabinet, sold separately and matched to the Tiomos series.

Tiomos Build Quality in Nickel Steel

The hinge is steel with a nickel finish, consistent with the Tiomos Impresso line. The snap-on arm is the same tool-free engagement across the Tiomos family, meaning the base plate goes to the cabinet once and the door lifts on and off without tools for finishing, painting, or adjustment. Post-install alignment is straightforward: the three-way cam adjustment covers height, side, and depth in a plus-3mm to minus-2mm range, enough to bring an inset door to a clean, even reveal after the cabinet is set and loaded. The 42/45mm dual bore pattern means the hinge drops into either the Grass boring pattern or a standard 45mm layout, which matters on a replacement job where the existing holes are already in the door.

Where This Hinge Belongs

This hinge is the right call for any run that includes a blind corner cabinet and calls for inset doors, on face-frame construction, frameless boxes, or a mixed job with both. Cabinet shops building corner kitchens in an inset style, designers specifying flush-face cabinetry around a corner, and contractors replacing worn hinges in an existing blind corner layout all land here. Doors up to 24mm thick fit without moving to a thick-door hinge. For the same blind corner application with a different overlay or closing type, other variants in this family cover those combinations.

A Clean Corner, Handled Correctly

Specify this hinge when a blind corner cabinet calls for inset doors and a self-closing action, on either face-frame or frameless construction, with the confidence that the door geometry will clear the adjacent cabinet every time.
