155 Degree Concealed Hinge for Wide-Swing Full Overlay Doors

This Grass Tiomos self-close hinge opens full overlay doors to 155 degrees, giving near-flat clearance for doors on frameless or face-frame cabinets where wide access is part of the design requirement.

Key Features

• 155 degree opening angle swings the door to near-flat for maximum cabinet access.
• Full overlay straight arm positions the door to cover nearly the entire cabinet side with a narrow reveal.
• Self-close spring pulls the door shut automatically over the last few degrees of travel.
• Dowel mount cup presses into the door's pre-bored dowel holes without cup screws, suited to CNC and production workflows.
• 42mm boring pattern matches Grass Tiomos boring rather than the 45mm pattern common to other brands.
• Three-way adjustment allows fine-tuning of height, depth, and side position after installation.

Wide-Swing Access on Full Overlay Doors

A 155 degree opening is a step beyond the 110 to 120 degree range of standard concealed hinges. When a door needs to swing nearly flat against the cabinet side, whether to clear an adjacent appliance, a wall, or a wide drawer bank below, this hinge delivers that range without requiring a special frame or modified cabinet. The full overlay straight arm keeps the door sitting over the cabinet side as expected, and the self-close spring means the door pulls itself shut once it falls within a few degrees of closed. The 35mm cup seats in the door bore, and the dowel mount presses into pre-drilled dowel holes in the door back for a secure, screw-free cup connection. The arm then snaps to a Grass base plate mounted to the cabinet, ordered separately.

Tiomos Build and Finish

The hinge is steel in a nickel finish. Grass Tiomos is built around snap-on arm engagement, meaning the arm connects to and releases from the base plate without tools. The three-way adjustment covers height, depth, and side, each with a few millimeters of range, so doors can be squared up evenly across a run after the cabinets are set. Maximum door thickness for this hinge is 32mm, which brings it into reach of thicker slab doors that standard 16 to 22mm hinges cannot accommodate.

Where This Hinge Works

This is the right pick when a project combines a wide-swing requirement with a full overlay door on either frameless or face-frame construction. Cabinet shops running CNC production will find the dowel mount a natural fit: no cup screws to drive, just pre-bored dowel holes and a press. Designers specifying kitchens or built-ins near walls or appliances can call out the 155 degree angle to guarantee the door clears without adding a bumper stop. Note that this hinge uses the Grass 42mm boring pattern, so verify bore spacing before ordering for a replacement application with existing holes. Pair it with the matching Grass Tiomos base plate for your cabinet construction type, ordered separately.
