Wide-Swing Concealed Hinge for Full Overlay Doors

This Grass Tiomos concealed hinge delivers a 120-degree opening on full overlay doors, with integrated soft-close and dowel mounting, for frameless and face-frame cabinet builds.

Key Features

• 120-degree opening angle swings the door wide for fuller access to cabinet contents than the standard 110-degree range.
• Integrated soft-close damps the door over the final arc so it settles quietly without slamming.
• Full overlay straight arm positions the door to cover nearly the entire cabinet side, leaving only a narrow reveal.
• Dowel mounting presses the cup into pre-bored dowel holes in the door for a clean, screw-free door-side installation.
• 42mm boring pattern is specific to the Grass Tiomos platform and must match the cabinet's bore layout.
• Three-way adjustment provides 3mm of travel in height, depth, and side for precise door alignment after hanging.

More Access, Same Clean Look

The 120-degree opening is the reason to reach for this hinge over a standard 110-degree version. Where a wall runs close to a cabinet side, or where the interior layout benefits from a door that clears farther out of the way, the extra swing makes a practical difference without changing how the door looks when closed. Full overlay geometry still covers the cabinet side with a narrow reveal, and the integrated soft-close brings the door back in quietly at the end of every swing. The 35mm cup seats in the door, and the arm connects to a Grass base plate mounted to the cabinet, ordered separately.

Tiomos Build and Finish

The hinge is steel with a nickel finish, built on the Grass Tiomos platform. Dowel mounting drives the cup into the door's pre-bored holes rather than securing it with screws, which suits CNC-heavy production environments where consistency across a run matters. The 12.6mm cup depth works with standard doors up to 24mm thick. The 42mm boring pattern is the Tiomos standard and is not interchangeable with the 45mm pattern used on other brands, so replacement sourcing and new installs both need to confirm the bore before ordering a plate.

Where This Hinge Fits the Job

Cabinet shops running Tiomos as their platform will find this the natural pick when a client's layout asks for wider door clearance, whether that is a corner cabinet that needs the extra swing to clear the adjacent run, a pantry where the contents come right to the door edge, or a kitchen design where a countertop appliance sits close to the cabinet opening. It works on both frameless and face-frame builds. For doors well under 16mm or over 24mm, a different hinge is needed. The Grass base plate is a separate purchase matched to your cabinet construction and the Tiomos series.
