Concealed Overlay Hinge for Face-Frame and Frameless Cabinets

The Grass Tiomos Impresso is a snap-on soft-close concealed hinge for overlay doors on face-frame and frameless cabinets, with toolless arm engagement and integrated soft-close built into the hinge body.

Key Features

• Integrated soft-close damps the door over the final closing arc, so it settles quietly without slamming.
• Toolless snap-on arm connects to the base plate without a screwdriver, speeding up door hanging and removal.
• 110 degree opening angle delivers standard everyday access across kitchen, bath, and casework doors.
• Overlay straight arm positions the door to cover the cabinet side with a narrow reveal.
• 42/45mm dual bore pattern offers flexibility when matching existing boring in Grass-specific or standard 45mm layouts.
• Three-way adjustment (height, side, and depth, each up to 3mm in either direction) allows fine-tuning after the door is hung.

Where This Hinge Belongs

This hinge is built for overlay doors on both face-frame and frameless cabinet boxes. In a face-frame cabinet, the door rides over the frame stile; in a frameless box, it overlays the panel edge directly. Either way, the straight arm carries the door to an overlay position, leaving a narrow reveal along the cabinet side. The 35mm cup bores into the back of the door, and the arm snaps to a Grass base plate mounted to the cabinet, ordered separately. Because Tiomos plates use a Grass-specific bore pattern and engagement, pair this hinge with Grass plates rather than plates from another brand.

Build and Finish

The hinge body is steel with a nickel finish. Maximum door thickness is 24mm, which extends the usable range slightly beyond the standard 22mm window, covering thicker slab doors without stepping up to a dedicated thick-door hinge. The 12.6mm cup depth seats cleanly in the standard bore and the 42/45mm dual bore pattern accommodates cabinetry already drilled to the Grass 42mm spacing as well as shops running a conventional 45mm layout.

Right for Volume Work and Careful Specifying

Cabinet shops running face-frame production, contractors fitting frameless boxes on a remodel, and designers specifying Tiomos across a full kitchen will all reach for this hinge for the same reason: the snap-on arm keeps installs moving, the soft-close performs consistently across repeated daily use, and the three-way adjustment handles the small variations that come with any real job. For installers already in the Grass ecosystem, the Tiomos Impresso fits a familiar workflow. For those new to Tiomos, note that the matching base plates are a separate purchase and are Grass-specific.

Common Questions

Quiet Closes, Clean Reveals, Installs That Move

Specify this hinge when the job calls for overlay doors that settle without slamming, hang quickly, and stay square over time on either frame style.
