Soft-Close Precision And Blind Corner Fit

The Grass Tiomos Impresso is a concealed blind corner hinge built for inset doors on frameless and face-frame cabinets, with integrated soft-close and toolless snap-on mounting. Where a standard concealed hinge would bind against the adjacent cabinet, this hinge's geometry lets the inset door clear the corner and settle quietly at every close.

Key Features

• Blind corner geometry restricts the swing so the door clears the adjacent cabinet without collision.
• Integrated soft-close damps the door over the final closing arc so it settles without slamming.
• Inset overlay positions the door flush inside the cabinet opening with an even reveal on all sides.
• Toolless snap-on mounting clips the arm to the base plate without a screwdriver for faster hanging and easy door removal.
• Three-way adjustment moves the door up to 3mm in height, side, and depth to dial in a consistent reveal after install.
• Works on both frameless and face-frame cabinets when paired with the appropriate Grass base plate, sold separately.

Solving the Blind Corner Problem

A standard hinge lets a door swing wide, which works fine on an open run but fails at a corner where a second cabinet sits adjacent. The blind corner hinge addresses this directly: its arm geometry holds the swing to an angle that keeps the door from striking the neighboring cabinet as it opens. On an inset door, where the panel sits inside the opening rather than over it, that clearance is even more critical because the door edge is already close to the frame. The 35mm cup bores into the back of the door, and the arm connects to a Grass base plate mounted to the cabinet side or stile. That base plate is a separate purchase and must be a Grass plate matched to your cabinet construction; plates are not interchangeable across brands.

Tiomos Build and Nickel Finish

This hinge is steel with a nickel finish, built on the Grass Tiomos Impresso platform. The Tiomos line is Grass's precision concealed system, and the snap-on arm engagement that defines it means the door can be hung or lifted off the cabinet without tools. The 12.6mm cup depth and the 35mm cup diameter suit standard door stock up to 24mm thick, which covers the range from typical cabinet-grade panels through slightly thicker slab doors. Boring follows the Grass 42/45mm dual pattern rather than the common 45mm pattern, so confirm your boring setup or CNC program before ordering replacements for an existing installation.

Where This Hinge Belongs

This is the hinge to specify when the design puts an inset door at a blind corner, on either a frameless Euro box or a face-frame cabinet. Cabinet shops running mixed construction will find it covers both without a separate SKU. It suits new installations and replacement work, though replacement buyers should verify the 42/45mm bore pattern against the existing holes before ordering. The 110 degree opening gives standard everyday access. Soft-close is built in, so no add-on damper is needed, and the restricted swing is a design feature of the blind corner application, not a shortcoming.

Quiet, Precise Doors at a Corner That Works

Specify this hinge when the job puts an inset door at a blind corner and the design calls for a clean flush face, a quiet close, and an install that moves fast with toolless mounting.
