Grass Tiomos Self-Close Hinge For Inset Doors on Frameless and Face-Frame Cabinets

This Grass Tiomos concealed hinge is built for inset doors that sit flush inside the cabinet opening, with a self-close spring and dowel-press mounting for both frameless and face-frame applications.

Key Features

• Inset overlay geometry positions the door flush within the cabinet opening for a clean, even reveal on all sides.
• Self-close spring pulls the door shut automatically over the last few degrees of travel.
• Dowel-press cup mounting presses into pre-bored dowel holes in the door, eliminating cup screws for fast production installs.
• Full crank arm carries the inset door position relative to the cabinet side.
• Three-way adjustment provides up to 3mm of height, side, and depth movement to dial in a consistent reveal after hanging.
• Works on both frameless and face-frame cabinets when paired with the appropriate Grass Tiomos base plate, sold separately.

Hanging a Door That Lives Inside the Opening

An inset door asks more of the hinge than an overlay door does. The door fits inside the cabinet opening rather than covering it, so the geometry has to hold the door precisely in the plane of the face frame or panel edge with an even gap all around. This Tiomos hinge uses a full crank arm to carry that inset position, and the 35mm cup bores into the door back to anchor it firmly. The hinge arm then connects to a Grass Tiomos base plate mounted to the cabinet, which is ordered separately and matched to your cabinet construction. Because Grass Tiomos plates are brand-specific, only Grass plates will engage this hinge correctly. The three-way adjustment range is what keeps inset doors square over time: small turns of the cam screws bring a door back into its opening after seasonal movement without pulling it off the plate.

Steel Build in a Nickel Finish

The hinge is plated steel in a Nickel finish, a neutral tone that recedes behind the door face once the cabinet is closed. The Tiomos platform is built for production environments, so the materials are chosen for durability across repeated cycling rather than for decorative presence. Doors up to 24mm thick fit within the cup geometry, which covers standard 18 to 22mm cabinet doors and leaves room for slightly heavier construction without moving to a thick-door hinge.

Who Reaches for This Hinge

Cabinet shops producing flush inset work, furniture builders fitting doors into face-frame carcasses, and contractors finishing high-specification residential kitchens or built-ins all land on this hinge for the same reason: the inset look demands a hinge that holds position reliably, and the Tiomos platform delivers that with snap-on engagement and a field-adjustable arm. The dowel-press cup suits CNC production lines where pre-boring the door is faster than setting cup screws. For overlay doors in the same run, the Tiomos family offers matching geometry in full and half overlay configurations so the install stays on one platform throughout.

Inset Fit, Held Precisely

When the design calls for doors that disappear into the cabinet face with a clean, consistent reveal, this Tiomos hinge keeps that fit square and repeatable across a full run of doors.
