Dowel-Mount Concealed Hinge for Half Overlay Doors

This Grass Tiomos self-close hinge is built for half overlay doors on both face-frame and frameless cabinets, with pre-mounted dowels that press into the door for a fast, screw-free cup installation on CNC and production lines.

Key Features

• Self-close spring pulls the door shut over the final degrees of travel so it latches without a push.
• Half overlay, half crank arm sets the door to a partial overlay, the correct geometry where two doors share a single partition.
• Dowel mount presses the cup into pre-bored dowel holes with no cup screws, ideal for CNC production workflows.
• 110 degree opening provides full everyday access to the cabinet interior.
• Three-way adjustment moves the door up to 3mm in height, side, and depth after installation.
• Fits doors up to 24mm thick, extending coverage to slightly thicker stock beyond the standard range.

Where Dowel Mounting and Half Overlay Work Together

Half overlay places each door over roughly half the cabinet side, the setup that lets two doors meet on one center partition without their arms colliding. The half crank geometry built into this hinge delivers that position precisely. On the door side, the dowel mount presses the 35mm cup into pre-bored dowel holes rather than using cup screws, which is the installation method production cabinet shops and CNC environments prefer for its speed and consistency. The hinge arm then connects to a Grass base plate mounted to the cabinet, ordered separately. Plates are specific to the Grass Tiomos system and are not interchangeable with other brands.

Steel Build in a Nickel Finish

The hinge is steel with a nickel finish. The Tiomos platform is a workhorse in production environments, and the three-way adjustment of 3mm in each direction keeps doors square as a project is installed and as cabinets settle in place. The self-close spring is a mechanical pull, not a damper: it draws the door shut from a few degrees open and holds it there. For a cushioned, quiet close, the soft-close Tiomos variant is the one to specify instead.

A Good Fit for Production and Volume Work

This hinge suits cabinet shops running CNC lines where dowel-bored doors are the norm, and contractors fitting frameless or face-frame cabinets that call for a partial overlay. It works on standard and slightly thicker doors up to 24mm. The Grass 42mm boring pattern governs the cup hole spacing, so confirm the boring matches before specifying this hinge as a replacement in an existing layout. A compatible Grass Tiomos base plate is required and sold separately.

Common Questions

Production-Ready Half Overlay on Any Run

Specify this hinge when the job calls for half overlay doors, dowel-bored production workflow, and a self-close that keeps every door latched without a damper adding to the cost.
