Dowel-Mount Concealed Hinge for Full Overlay Doors

The Grass Tiomos is a full overlay concealed hinge with integrated soft-close and a dowel-mount cup, built for production environments on both face-frame and frameless cabinets.

Key Features

• Integrated soft-close damps the door over the final closing arc so it settles quietly without slamming.
• Dowel-mount cup presses into pre-bored dowel holes in the door for fast, screw-free cup installation in CNC and production workflows.
• Full overlay straight arm positions the door to cover nearly the entire cabinet side, leaving a narrow reveal.
• 110 degree opening delivers standard everyday access on kitchen, bath, and casework doors.
• Three-way adjustment provides up to 3mm in height, side, and depth to bring doors to an even reveal after installation.
• Works on face-frame and frameless cabinets when paired with the matching Grass Tiomos base plate, sold separately.

A Hinge Sized for Production Speed

The dowel-mount cup is where this hinge earns its place on a production floor. Rather than driving cup screws by hand or at the press, the cup carries pre-attached dowels that drop straight into the bored holes in the door, locking the hinge position without fasteners. Paired with a CNC boring program, that means consistent placement across a full run of doors. The 35mm cup seats in the door, the arm connects to a Grass Tiomos base plate on the cabinet, and the plate is ordered separately. Grass Tiomos plates are brand-specific, so use a Grass plate matched to your cabinet construction and the overlay you need.

Steel Build in a Nickel Finish

The hinge is plated steel with a nickel finish. The Tiomos platform is Grass's premium concealed line, and the integrated soft-close is built directly into the hinge body rather than added as a separate damper clip. The door slows on its own over the last few degrees of travel, which protects both the door and the cabinet face across years of daily use. Three-way adjustment handles the inevitable settling of a full cabinet run, keeping reveals consistent without pulling and re-hanging doors.

Where This Hinge Belongs

Cabinet shops running CNC equipment will get the most from the dowel-mount design, where pre-boring for dowels is already in the program and screw-on cup installation is the bottleneck to skip. It suits frameless production cabinets and face-frame boxes equally, covering the range of cabinet types that show up on a typical commercial or residential job. Standard doors in the 16 to 24mm range fit this hinge. The 42mm boring pattern is specific to Grass Tiomos, so for replacement work, verify the existing door bore matches before ordering.
