Wide Swing And Half Overlay Fit

This Grass Tiomos hinge brings a 155 degree opening arc to half overlay doors on both face-frame and frameless cabinets, with a self-close spring and a dowel-mount cup that presses into the door without cup screws.

Key Features

• 155 degree opening angle swings the door nearly flat, clearing the cabinet interior for full, unobstructed access.
• Half overlay, half crank arm positions the door over part of the cabinet side, the standard geometry for two doors sharing one center partition.
• Self-close spring pulls the door shut over the last few degrees of travel.
• Dowel-mount cup presses into pre-bored dowel holes, eliminating cup screws for a faster CNC and production workflow.
• Three-way adjustment moves the door up to 3mm in height, side, and depth after the plate is set.
• Suits doors up to 32mm thick, handling heavier stock beyond the standard range.

Where a 155 Degree Swing Makes the Difference

Most concealed hinges stop at 110 degrees, which is fine for everyday access. This hinge opens to 155 degrees, bringing the door close to parallel with the cabinet side. That clearance matters on cabinets placed near appliances, walls, or adjacent units where a standard swing would cut off reach into the interior. At half overlay, it fits naturally on double-door cabinets where two doors meet on a shared partition, each covering roughly half the side panel. The 35mm cup bores into the back of the door and the hinge connects 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.

Steel Build With a Production-Ready Mount

The hinge is steel with a nickel finish. The dowel-mount cup is the detail that sets the installation apart from a standard screw-mount hinge: pre-attached dowels press into bored holes in the door face, so there are no cup screws to drive. For CNC shops and production lines running volume, that step adds up. Once the plate is mounted and the hinge is set, the three-way adjustment handles the fine work, bringing doors to an even reveal without pulling them off the cabinet.

Built for Shops and Installers Running Volume

This hinge suits cabinet shops, millwork operations, and contractors who need wide-opening half overlay doors and want a mount that keeps pace with CNC boring. It works on frameless box construction and face-frame cabinets alike, so a single SKU covers both cabinet types on a mixed job. For doors in standard 16 to 22mm stock or thicker panels up to 32mm, the Tiomos geometry handles the load. This is a self-close hinge, meaning the spring draws the door shut. For a damped, cushioned close, the soft-close Tiomos version is the right direction instead.

Full Reach, Clean Close, Fast Install

Specify this hinge when the job calls for a wide-opening half overlay door that closes on its own, mounts fast in a CNC workflow, and works across both face-frame and frameless construction.
