Wide-Angle Soft-Close Hinge for Full Overlay Doors

This Grass Tiomos concealed hinge opens to 155 degrees and delivers integrated soft-close on full overlay doors for both face-frame and frameless cabinets, with a screw-on mount for a direct, secure connection.

Key Features

• 155 degree opening angle swings the door nearly flat for maximum interior access in tight or shallow spaces.
• Integrated soft-close damps the door through the final closing arc so it settles without impact.
• Full overlay straight arm positions the door to cover nearly the entire cabinet side with a narrow reveal.
• Screw-on mounting fastens the arm directly to a Grass base plate for a fixed, tool-independent connection.
• Works on both face-frame and frameless cabinets when paired with the matching Grass Tiomos base plate.
• Three-way adjustment moves the door height, side, and depth within a 3mm range each direction for a clean, even reveal.

Where the 155 Degree Opening Earns Its Keep

A standard 110 degree hinge gets the door out of the way for most cabinet access, but there are applications where that is not enough. Corner cabinets, narrow base runs, appliance garages, and butler pantry walls often need a door that folds back far enough to stay clear of the work zone. At 155 degrees, this hinge comes within a few degrees of lying flat against the cabinet side. That swing clears adjacent surfaces, keeps the door out of the cook's path, and makes retrieving items at the back of a cabinet easier without having to reach past a door hanging at mid-swing.

The 35mm cup bores into the back of the door, and the arm screws to a Grass Tiomos base plate on the cabinet. That plate is a separate purchase and must be a Grass Tiomos plate: arm engagement is Grass-specific and will not connect to another brand's plate.

Steel Construction and a Soft-Close Built for Daily Use

The hinge is plated steel in a Nickel finish. The 10mm cup depth and straight arm geometry are matched for standard doors up to 32mm thick, which covers most production and custom cabinet stock. Soft-close at 155 degrees is a specific engineering achievement in this hinge family: on wide-angle hinges with a shorter closing arc, the damping has less travel to work with, and Grass's integrated damper is calibrated for this angle. The close is quiet and controlled at the widest opening this series offers with soft-close.

The Right Fit for This Hinge

Cabinet shops, finish carpenters, and installers who regularly work on corner layouts, island back-panels, or high-traffic utility areas will find the wide swing useful where a standard-angle hinge would leave the door in the way. It suits frameless and face-frame construction equally, so specifying it across a mixed job requires no workflow change. The screw-on mount is the appropriate choice when a tool-free snap-on connection is not needed or when the installation calls for a firmly locked arm-to-plate connection out of the box. For doors thicker than 32mm, a thick-door hinge is the correct choice.
