Dowel-Mount Concealed Hinge For Wide-Swing Full Overlay Doors

This Grass Tiomos self-close hinge mounts to the door via press-in dowels and delivers a 155-degree opening arc on full overlay doors, on both face-frame and frameless cabinets.

Key Features

• 155-degree opening angle swings the door nearly flat for exceptional interior access.
• Self-close spring draws the door shut automatically once released within the closing range.
• Full overlay straight arm positions the door so it covers nearly the entire cabinet side with a narrow reveal.
• Dowel mount presses into bored dowel holes in the door for a screw-free, CNC-ready cup attachment.
• Three-way adjustment provides height, side, and depth movement of up to 3mm in each direction for precise door alignment.
• 35mm cup in a 10mm-deep bore seats the hinge flush in standard door stock.

Wide-Swing Access on Full Overlay Doors

The 155-degree opening is the widest angle available with a closing mechanism in the Tiomos line. At that swing, the door travels far enough past the cabinet face to clear the opening completely, giving unobstructed access to the interior. That is the payoff for appliance garages, pantry pulls, and any cabinet where a door stopping at 110 degrees would block reach-in access. The full overlay arm places the closed door over nearly the entire cabinet side, and the hinge mounts to a Grass base plate on the cabinet, sold separately. Grass plates are specific to the Tiomos system and are not interchangeable with plates from other brands.

Dowel Mounting and Steel Construction

The cup attaches to the door through press-in dowels rather than cup screws. In a CNC or production shop where doors come off the line with dowel holes already bored, this speeds the cup installation to a press-fit with no fastener work at the door. The hinge body is steel with a nickel finish. Three-way adjustment at the arm lets an installer dial in height, side, and depth independently after the cabinet is set, which is what keeps a row of doors running at a consistent reveal over time.

Where This Hinge Fits

This is a hinge for production cabinet shops and commercial installers working on frameless or face-frame cabinets where CNC boring is the standard workflow and where wide door travel matters. Pantry cabinets, tall utility pulls, and entertainment units are natural fits for the 155-degree arc. Because the closing mechanism here is a self-close spring rather than a damper, this hinge pulls the door shut firmly; if the project calls for a cushioned, quiet settle, the soft-close version of the Tiomos line is the alternative to specify. Maximum door thickness for this hinge is 32mm.

Common Questions

Full Clearance, Fast Install, Consistent Results

Specify this hinge when the job calls for a wide-opening full overlay door on frameless or face-frame cabinets and the workflow runs through a CNC line where dowel boring is already in the program.
