Thick Door Geometry And Full Overlay Fit

This Grass Tiomos hinge is built specifically for thick doors, delivering full overlay positioning and integrated soft-close on both face-frame and frameless cabinets via a screw-on mount.

Key Features

• Thick door engineering accommodates doors up to 36mm, where a standard concealed hinge cup will not seat correctly.
• 95 degree opening angle is the correct swing for a thick door to clear the cabinet front without binding.
• Integrated soft-close damps the door over the final closing arc so it settles quietly without slamming.
• Full overlay straight arm positions the door to cover nearly the full cabinet side, leaving a narrow reveal.
• Screw-on mounting fastens directly and firmly to the cabinet without requiring pre-drilled system holes.
• Three-way adjustment provides plus or minus movement in height, side, and depth to dial in the reveal after hanging.

Where Thick Doors Need a Different Hinge

A standard concealed hinge is engineered for doors in the 16 to 22mm range. Push beyond that, and the cup geometry no longer seats cleanly and the arm cannot carry the extra mass without the door pulling out of position. This Tiomos hinge is built from the ground up for thick doors up to 36mm, with a 35mm cup and modified arm geometry that accounts for the added depth and weight. The 95 degree opening is not a restriction here, it is the angle that lets a thick door clear the cabinet face cleanly as it swings, which a wider arc would not reliably do on heavy material. The hinge mounts to a separate base plate, sold separately, matched to your cabinet construction. Use a Grass plate; plates are brand and series specific and a non-Grass plate will not connect to this hinge.

Steel Build and a Quiet Close on Heavy Doors

The hinge is plated steel in a nickel finish. Soft-close earns its keep on thick doors more than almost anywhere else: the extra mass of a heavy panel amplifies the impact of an uncontrolled close, and the integrated damper absorbs that energy so the door settles without stress on the joint. Screw-on mounting gives a firm, direct connection that holds position under repeated use with a heavier door, and the three-way adjustment keeps the reveal even as the cabinet settles over time.

Shops and Installers Working With Solid or Built-Up Panels

This hinge fits cabinet shops building with thick solid wood doors, doubled-up panels, or overlay frames that push past the standard thickness window. It works equally on frameless boxes and face-frame cabinets, so one SKU covers either construction type on a mixed job. For doors that fall inside the standard 16 to 22mm range, a standard Tiomos hinge is the right call. For any door above that threshold and up to 36mm, this is the hinge to reach for.

Common Questions

The Right Hinge Lets a Heavy Door Hang Right

Specify this Tiomos hinge when the door thickness rules out a standard cup and the job still calls for full overlay, a quiet close, and hardware built to last on a heavier panel.
