Soft-Close Thick Door Hinge for Inset Doors

The Grass Tiomos Impresso is a concealed soft-close hinge built for thick inset doors up to 36mm on face-frame and frameless cabinets, with toolless snap-on arm engagement and three-way adjustment.

Key Features

• Thick door rating to 36mm accommodates doors well beyond the standard 22mm window, where a standard hinge cup would not seat correctly.
• Inset geometry with full crank arm positions the door flush inside the cabinet opening with an even reveal on all sides.
• Integrated soft-close dampens the door over the final closing arc so it settles quietly without slamming.
• 95 degree opening angle is the engineered limit that lets a thick door clear the cabinet front without binding.
• Toolless snap-on mounting clips the arm to the base plate without tools for fast door hanging and removal.
• Three-way adjustment provides 3mm of travel in height, side, and depth to dial in a flush, even reveal after install.

Built for Thick Inset Doors That Have to Clear

An inset door sits flush inside the cabinet opening rather than over it, and the reveal around all four edges is what defines the look. When that door is also thick, a standard hinge will not seat the cup correctly and the arm geometry will not carry the door to the right position. This hinge solves both problems: the cup is sized and the arm geometry is engineered for doors up to 36mm thick, and the inset crank places the door flush within the opening.

The 95 degree opening is the correct swing for this application. A thick door sweeps a larger arc than a standard door, and 95 degrees is the angle that lets it clear the cabinet face cleanly. This is not a reduced-feature spec; it is the geometry thick doors require. The 35mm cup bores into the door at a 12.6mm cup depth. The arm connects to a Grass base plate on the cabinet, which is sold separately. Tiomos plates use the Grass bore pattern, with a 42/45mm dual boring option, so confirm the plate to your cabinet setup before ordering.

Tiomos Construction in Nickel

The hinge is plated steel in a nickel finish. Tiomos is Grass's premium concealed platform, and the Impresso variant carries the soft-close damping built into the hinge body rather than relying on a separate add-on. The snap-on arm engagement is a Tiomos platform feature: the arm clicks onto the mounted plate, and a release lets you take the door off without tools. That mechanism matters on heavy thick-door panels that need to come down for finishing or adjustment.

Where This Hinge Belongs

This hinge suits cabinet shops, custom builders, and millwork installers working with thick-panel inset doors on frameless or face-frame boxes. Furniture builders using 30mm or thicker stock in a flush-face design will find the geometry here matches the work. It is not the right pick for standard doors in the 16 to 22mm range; for those, the standard Tiomos inset hinge covers the application at a lower cost. For doors that overlay the cabinet side rather than sitting inside it, an overlay Tiomos variant is the correct selection instead.

Common Questions

Flush, Quiet, and Sized for the Door

When the design calls for a thick inset door that closes quietly and sits square in its opening, this hinge provides the geometry, the damping, and the adjustment range to make it work.
