120-Degree Swing And Full Overlay Fit

This Grass Tiomos concealed hinge opens to 120 degrees and hangs full overlay doors on face-frame or frameless cabinets, with a self-close spring and dowel cup mounting designed for CNC-bored door panels.

Key Features

• 120-degree opening angle delivers a wider-than-standard swing for better access inside the cabinet.
• Full overlay straight arm positions the door to cover nearly the entire cabinet side, leaving a narrow reveal.
• Self-close spring draws the door shut automatically over the last few degrees of travel.
• Dowel cup mounting presses pre-mounted dowels into CNC-bored holes in the door panel, no cup screws needed.
• Three-way adjustment moves the door up to 3mm in height, side, and depth after mounting.
• Works on face-frame and frameless cabinets when paired with the matching Grass base plate.

Where the 120-Degree Opening Earns Its Place

Standard concealed hinges open to 110 degrees, which suits most everyday cabinet doors. At 120 degrees, this Tiomos hinge swings the door back far enough to give noticeably better clearance inside the box, a practical advantage on deeper base cabinets, corner pull-outs, and appliance garages where reaching past the door edge matters. The full overlay geometry covers the cabinet side as a solid face, and the self-close spring pulls the door home once released. The hinge seats its 35mm cup in the door and connects to a Grass base plate on the cabinet, which is sold separately. Grass plates are not interchangeable with other brands, so order from the Grass Tiomos plate range to match this hinge.

Steel Build With Dowel-Ready Installation

The hinge is plated steel in a nickel finish. The dowel cup is what sets the production pace here: instead of driving cup screws at the machine, the pre-mounted dowels press directly into the CNC-bored holes in the door panel. That one step removes fastener handling from the door-boring station and keeps throughput steady. After hanging, the three-way cam adjustment dials in height, side, and depth to bring the door to an even reveal without pulling it off the plate. Maximum door thickness for this hinge is 24mm, which covers standard cabinet doors and a range of thicker MDF and soft-maple slab fronts.

The Right Hinge for Production and High-Volume Work

The dowel format makes this hinge a natural fit for cabinet shops running CNC-bored panels at volume, where screwless cup attachment keeps the line moving. It also suits contractors and installers who receive pre-bored doors and want a hinge that drops into place. Because this hinge works on both face-frame and frameless boxes, it can cover a mixed-construction job without switching to a different SKU family. For a damped, cushioned close rather than a spring pull, the soft-close version of this series is the closest alternative.
