Grass Tiomos Impresso Concealed Hinge for Flush Inset Doors

The Grass Tiomos Impresso is a concealed soft-close hinge built for inset doors on both face-frame and frameless cabinets, with toolless snap-on mounting and three-way adjustment for a clean, even fit.

Key Features

• Integrated soft-close slows the door through the final degrees of travel so it settles quietly against the opening.
• Inset geometry, full crank arm positions the door flush inside the cabinet opening with a consistent reveal on all sides.
• 110 degree opening angle gives full everyday access from a flush-fitted inset door.
• Toolless snap-on mounting connects the arm to the base plate without a screwdriver, and releases the same way.
• Three-way adjustment of plus or minus 3mm in height, side, and depth brings doors into alignment after the cabinet is built.
• 42/45mm dual bore pattern fits both the Grass native 42mm layout and the common 45mm spacing found in many production setups.

The Right Hinge for a Flush Inset Door

Inset doors sit inside the cabinet opening rather than covering it, and that flush look depends entirely on controlled geometry. The Tiomos Impresso carries the full crank arm that places the door at the inset position, letting it clear the frame as it swings open to 110 degrees without binding. The 35mm cup bores into the back of the door at a depth of 12.6mm, and the hinge connects to a Grass base plate mounted to the cabinet. That plate is a separate purchase, matched to your cabinet construction and the Grass Tiomos system. Maximum door thickness for this hinge is 24mm, which covers standard solid wood and MDF inset panels.

Tiomos Build Quality in Nickel

The Impresso is steel construction with a nickel finish. Tiomos is Grass's premium concealed platform, and the soft-close in this hinge is built into the mechanism rather than added as a clip-on adapter, so there is nothing extra to source or install. For inset work especially, that integrated damping earns its keep: a tight-fitting door that slams daily will wear its reveal over time, and the soft-close takes that impact away with every close. The dual 42/45mm bore pattern is a Tiomos detail worth knowing at install time. Confirm your cabinet's boring against both options before drilling.

Face-Frame and Frameless Cabinets, One Hinge

This hinge is rated for both face-frame and frameless construction, which makes it a single stocking item for shops that build both cabinet types. Inset work appears most often in furniture-grade face-frame cabinetry, built-ins, and premium kitchen projects where the flush face is part of the design intent. It also suits frameless boxes where a minimal reveal is specified. Because the plate mounts separately, use a Grass Tiomos plate matched to your cabinet type. Grass plates are not interchangeable with plates from other brands.
