Wide-Angle Opening And CNC-Ready Dowel Mounting

This Grass Tiomos concealed hinge brings a 120 degree opening arc and dowel-style cup attachment to full overlay doors on both frameless and face-frame cabinets, with integrated soft-close built into the hinge.

Key Features

• 120 degree opening swings the door wider than the standard 110 degree range, giving better access to the cabinet interior.
• Integrated soft-close damps the door through the final closing arc so it settles quietly without slamming.
• Full overlay straight arm positions the door to cover nearly the entire cabinet side, leaving a narrow reveal.
• Dowel cup attachment presses pre-mounted dowels into bored dowel holes in the door, with no cup screws needed.
• Fits doors up to 24mm thick, extending the usable range beyond the standard 22mm window.
• Three-way adjustment dials in height, depth, and side position after hanging, each axis independent.

Where the Extra Swing Makes a Difference

An extra ten degrees of opening sounds small, but at the cabinet it means the door clears more of the opening and stays out of the way on tighter runs. That matters in galley kitchens where adjacent doors swing close to each other, in butler's pantries and utility cabinets where bulkier items go in and out, and on any run where the standard 110 degree stop leaves the door in the way of reaching the back of the shelf. The 120 degree arc is engineered clearance, not just convenience.

The hinge works on both frameless and face-frame boxes. The 35mm cup bores into the door, and the arm connects to a Grass base plate on the cabinet, ordered separately. Match the plate to the Tiomos series and your cabinet construction. Plates from other brands will not connect to this hinge.

Steel Build With a Dowel Connection

The hinge is plated steel in a nickel finish. The dowel attachment sets this version apart from screw-on cup installations: the cup carries pre-mounted dowels that press into the door's bored dowel holes without cup screws, a clean fit suited to CNC production lines and shops boring doors in volume. The 35mm cup seats at 12.6mm depth. Soft-close is built into the Tiomos hinge body, so no add-on damper or separate adapter is needed. The three-way adjustment, plus or minus a few millimeters on each axis, is enough to bring a full run of doors to a consistent reveal after the cabinets are set.

A Good Fit for Production Shops and Careful Specifiers

This hinge earns its place in two situations. First, in CNC and production environments where dowel boring is already part of the door-prep workflow and screw-on cup installation would slow things down. Second, on any project where a wider swing is part of the design brief, whether that is a homeowner requesting maximum access or a designer specifying a kitchen layout where tight clearances demand every degree the hinge can offer. The 24mm maximum door thickness also makes it a practical choice for shops working with slightly thicker door stock where a standard hinge would fall short.

For doors above 24mm, move to a thick-door hinge. For the same Tiomos soft-close performance with screw-on cup mounting, the screw-mount version of this series is the alternative.
