Grass Tiomos Thick Door Hinge for Overlay Face-Frame and Frameless Cabinets

The Grass Tiomos thick door hinge is a self-close concealed hinge engineered for overlay doors built from stock thicker than standard, on both face-frame and frameless cabinets. Dowel mounting drops it into production-bored door blanks without cup screws.

Key Features

• Thick door geometry supports doors up to 36mm, where a standard hinge cup would not seat correctly.
• Self-close spring pulls the door shut over the final degrees of travel.
• 95 degree opening angle is the correct swing for thick overlay doors, giving full access while keeping the door clear of the cabinet front.
• Dowel mount presses into pre-bored dowel holes for a screw-free door-side installation, suited to CNC and production workflows.
• 42mm boring pattern is the Grass Tiomos standard; confirm your cabinet boring matches before ordering a replacement.
• Three-way adjustment moves the door up to 3mm in height, side, and depth after the cabinet is assembled.

Built for Doors a Standard Hinge Cannot Handle

Standard concealed hinges are sized for doors in the 16 to 22mm range. Push past that window and the cup geometry no longer seats properly in the door's face. This hinge is purpose-built for thick-door stock up to 36mm, with the modified arm geometry and cup depth that thick material demands. The 95 degree opening is not a restriction to work around; it is the angle that lets a thick overlay door clear the cabinet front cleanly without binding on the frame or an adjacent door. The hinge mounts to a separate Grass Tiomos base plate on the cabinet, ordered separately, and that plate is specific to the Tiomos series.

Nickel Steel with Dowel Mounting

The hinge is steel with a nickel finish. The dowel mount is the production-shop detail: rather than cup screws, pre-mounted dowels press directly into the door's bored dowel holes, so there is nothing to drive or strip at the door. That same logic runs through the snap-on arm engagement to the Tiomos plate, keeping the install moving in a high-volume environment. Three-way adjustment, each axis running plus 3mm to minus 2mm, is enough to bring doors into a consistent reveal after the boxes are set and the shop has moved on to the next cabinet run.

Who Reaches for This Hinge

Cabinet shops building thick-slab doors in a solid or engineered material, furniture makers working in stock heavier than typical cabinet-grade sheet goods, and contractors replacing hinges on an existing thick-door installation are the buyers this hinge is built for. It works on both frameless boxes and face-frame construction, so it covers the mixed-specification jobs that come through a shop or a remodel. For doors in the standard 16 to 22mm range, a standard Tiomos hinge is the right pick. For doors beyond 22mm up to 36mm, this is the one to specify.

Common Questions

Thick-Door Performance Without the Guesswork

Specify this hinge when the door stock goes beyond what a standard concealed hinge can handle, and the job calls for a self-close that works on both face-frame and frameless boxes.
