Nickel Concealed Hinge for Wide-Swing Overlay Doors

This Grass Tiomos self-close hinge is built for overlay doors on face-frame and frameless cabinets, opening to 120 degrees and mounting with press-in dowels for a clean, production-ready install.

Key Features

• 120 degree opening provides a wider swing than the standard 110 degree hinge, giving better access to the full cabinet interior.
• Self-close spring draws the door shut automatically over the last few degrees of travel.
• Overlay geometry with straight arm positions the door to cover the cabinet side, leaving a narrow reveal.
• Dowel mount cup presses into pre-bored door holes without cup screws, suited to CNC and production workflows.
• 42mm bore pattern is the Grass Tiomos standard spacing; confirm existing holes match before ordering as a replacement.
• Three-way adjustment moves height, side, and depth independently so doors can be squared after the cabinet is set.

Where the 120 Degree Opening Makes the Difference

On a standard 110 degree hinge, the door stops short of fully clearing the opening. On this hinge it swings to 120 degrees, which lets a hand or a drawer pull clear the corner more comfortably on base cabinets, appliance garages, and anywhere the extra arc matters. The overlay straight arm sits the door over the cabinet side on either a frameless box or a face-frame cabinet. The 35mm cup bores 12.6mm into the back of the door, and the arm snaps to a Grass base plate mounted on the cabinet, sold separately. Matching the plate to the Tiomos series keeps the snap-on engagement working correctly; plates from other brands will not connect.

Steel Construction in a Nickel Finish

The hinge body is steel finished in nickel. For cabinet shops running production, the dowel cup is the practical detail: pre-mounted dowels press into bored holes without cup screws, cutting installation steps per door. The three-way adjustment at plus or minus 2 to 3mm in each direction handles the minor variation that shows up across a full run of doors. Doors up to 24mm thick are within spec for this hinge; for anything thicker, a thick-door hinge is the right choice.

Face-Frame and Frameless, Production or Custom

This hinge works on both face-frame and frameless cabinets, so it fits shops and contractors who are not locked to one construction style. The dowel mount is a natural fit for CNC-drilled production doors, and the Tiomos snap-on plate connection speeds door hanging on a run. For a project where the install pace is less critical, the screw-cup version of this hinge covers the same application without the pre-bored dowel requirement. This is a self-close hinge: the spring pulls the door shut but does not cushion the contact. If a quietly damped close is part of the spec, the Tiomos soft-close version is the one to choose instead.

Common Questions

A Wider Swing, Faster to Install

Specify this hinge when the job calls for overlay doors that open beyond the standard arc and the workflow benefits from a dowel-cup, production-ready install on face-frame or frameless boxes.
