Nickel Concealed Hinge for Wide-Opening Overlay Doors

The Grass Tiomos Impresso is a soft-close concealed hinge built for overlay doors on face-frame and frameless cabinets where a 155 degree opening angle is the goal — the widest swing available with integrated soft-close in the Tiomos line.

Key Features

• 155 degree opening swings the door nearly flat, clearing the cabinet front and giving unobstructed access to the interior.
• Integrated soft-close damps the door smoothly over the final arc of closing so it settles without slamming.
• Toolless snap-on arm mounts to the base plate without a screwdriver, speeding door hanging and removal.
• Straight arm overlay geometry positions the door over the cabinet side or face-frame stile for a standard overlay reveal.
• 42/45mm dual bore pattern fits both the Tiomos native spacing and common 45mm pre-drilled cabinets.
• Three-way adjustment dials height, side, and depth within a 5mm total range to bring doors into an even reveal after hanging.

The Case for 155 Degrees

Most everyday concealed hinges open to 110 degrees, which handles standard cabinet access without issue. But when the cabinet sits against a wall, flanks an appliance, or is part of a kitchen island where someone reaches in from the side, a wider swing makes a real difference. At 155 degrees the door swings back nearly parallel to the cabinet side, clearing the opening completely so drawers pull out without the door in the way and reach-in access is unobstructed. This is the widest opening angle the Tiomos line offers with soft-close built in — a useful ceiling to know when specifying for a wide-angle application that still needs a quiet close.

Tiomos Build and Nickel Finish

The hinge is plated steel in a nickel finish, consistent with the Tiomos Impresso line's standard hardware palette. The 35mm cup seats in a 10mm-deep bore in the door, and the snap-on arm engages a Grass base plate mounted to the cabinet, sold separately. Plates are Grass-specific: the Tiomos snap-on engagement is proprietary, so a base plate from another brand will not connect. The 42/45mm dual bore pattern is the Tiomos standard and accommodates both the native Grass spacing and the 45mm pattern common in pre-drilled production boxes, which simplifies replacement work on existing Tiomos installations or on production cabinets with 45mm boring.

Who Reaches for This Hinge

Cabinet shops specifying wide-swing access on a kitchen run will find this hinge earns its place on base cabinets near appliances, pantry pulls, and island cabinets where doors need to clear fully. It works on both frameless boxes and face-frame construction, so a mixed project does not require a separate SKU for each cabinet type. Designers specifying handle-less or handle-light kitchens also value the wide clearance, since a door that opens flat eliminates the reach obstacle. For doors thicker than 22mm, move to a thick-door hinge. If the project calls for the full 170 degree swing, note that soft-close is not offered at that angle — the 155 degree Tiomos is the closest wide-angle option with a damped close.
