Dowel-Mount Concealed Hinge for Wide-Swing Overlay Doors

This Grass Tiomos concealed hinge opens to 155 degrees with integrated soft-close, mounts via pre-installed dowels for a screwless door install, and fits full overlay doors on both face-frame and frameless cabinets.

Key Features

• 155-degree opening angle delivers wide, near-flat clearance that makes deep cabinet interiors fully accessible.
• Integrated Tiomos soft-close damps the door through the final closing arc so it settles silently without slamming.
• Dowel mounting presses the cup into the door's pre-bored dowel holes with no cup screws needed.
• Full overlay straight arm positions the door to cover nearly the entire cabinet side, leaving only a narrow reveal.
• Three-way adjustment provides up to 3mm of movement in height, depth, and side to bring doors into alignment after install.
• Fits doors up to 32mm thick, extending its range beyond the standard 16 to 22mm window.

Maximum Access From a Concealed Hinge

At 155 degrees, this hinge swings the door nearly flat beside the cabinet, which is the widest opening available with soft-close built in. That clearance pays off on pantry cabinets, appliance garages, and deep base or wall cabinets where reaching the back means the door has to get completely out of the way. The 35mm cup bores into the door in the standard position, and the dowel mount presses in without cup screws, keeping the door-side install fast and clean in production runs. The arm then snaps onto a Grass base plate on the cabinet, which is ordered separately and specific to the Tiomos system.

Steel Build in a Nickel Finish

The hinge body is steel with a nickel finish. The Tiomos platform builds soft-close into the hinge itself rather than relying on an add-on damper, so the mechanism is compact and the arm engagement stays uncluttered. The three-way adjustment range handles the small variations that show up after a cabinet run is set: doors can be moved independently without removing them, which keeps the reveal even across a full bank. Maximum door thickness of 32mm means this hinge stays usable on slightly heavier slab doors that would exceed a standard hinge's range.

Where This Hinge Belongs

This is the hinge for any full overlay door where wide clearance is the priority and a quiet close is expected. It works on face-frame and frameless cabinets alike. Cabinet shops running CNC with pre-bored dowel holes will find the screwless cup install especially efficient at volume. Designers specifying pantry columns, tall cabinets, or entertainment centers where full interior access matters should note the 155-degree swing. For installations where 110 degrees is enough and the wide angle is not needed, a standard Tiomos is the leaner option. And because 155 degrees is the maximum angle at which Tiomos integrates soft-close, this hinge covers the widest opening available with damped closing in the Grass lineup.
