120-Degree Concealed Hinge for Half Overlay Doors

This Grass Tiomos soft-close hinge is built for half overlay doors on both face-frame and frameless cabinets, delivering a wider-than-standard 120-degree swing with integrated soft-close and a dowel mount that locks into CNC-bored door holes.

Key Features

• 120-degree opening angle provides more interior clearance than the standard 110-degree swing, useful in tighter kitchens and high-access cabinets.
• Integrated soft-close damps the door over the final closing arc so it settles quietly without impact.
• Half overlay, half crank arm positions two doors cleanly on a shared center partition with a consistent reveal.
• Dowel mount cup presses into pre-bored door holes, eliminating cup screws and speeding production installs.
• Three-way adjustment dials height, side, and depth independently after hanging.
• Suits doors up to 24mm thick, covering standard and moderately thick cabinet doors.

More Swing Where the Layout Demands It

On a standard run of cabinets, 110 degrees is enough. In a galley kitchen, a corner run, or a peninsula where the door needs to clear adjacent furniture or appliances, a 120-degree swing changes what is reachable without repositioning. This hinge delivers that wider arc on half overlay doors, the configuration used wherever two doors share a center partition or where a partial overlay is the specified layout. The 35mm cup bores into the door; the arm connects to a Grass base plate mounted to the cabinet side, ordered separately. For this hinge, the 42mm Grass boring pattern applies at the door side, so confirm that your setup matches before boring new holes or ordering for replacements.

Tiomos Build and Soft-Close That Holds Up

The hinge is steel with a nickel finish, built to Grass Tiomos tolerances. The snap-on arm engages the base plate without tools, and the integrated soft-close is part of the hinge body rather than an add-on adapter. That means the damping is consistent across every door on the run without the variability of separately clipped dampers. The 12.6mm cup depth and the half crank geometry are engineered together, so the overlay and the reveal stay right as long as the plate is matched correctly. Three-way adjustment of plus or minus a few millimeters in each direction brings the doors to square after the cabinets settle.

Who Reaches for This Hinge

Cabinet shops running CNC production work value the dowel mount: it skips the cup screws entirely, which saves time across a large batch of doors. Contractors specifying for a kitchen where door clearance is tight will appreciate the 120-degree opening without having to move up to a specialty wide-angle hinge. This hinge fits both face-frame and frameless boxes, so it covers most cabinet types in a single SKU. Use matching Grass Tiomos plates; Tiomos arm engagement is Grass-specific and will not connect to plates from other brands. A compatible Grass base plate is sold separately.

Wide Access and a Quiet Close, Built Into the Hinge

Specify this Tiomos hinge when a half overlay layout needs more door clearance than a standard swing provides and a built-in soft-close that keeps the close consistent across the run.
