Dowel-Mount Concealed Hinge For Half Overlay Doors

This Grass Tiomos concealed hinge is built for half overlay doors on face-frame and frameless cabinets, combining dowel-press installation with integrated soft-close in a 110-degree half-crank design.

Key Features

• Integrated soft-close damps the door over the final closing arc so it settles quietly without slamming.
• Half overlay, half crank arm positions the door to cover half the cabinet side, the right geometry for two doors sharing a center partition.
• Dowel-press mounting drives the cup directly into bored dowel holes for a fast, screw-free door-side connection.
• 110-degree opening delivers full everyday access for standard cabinet doors.
• Three-way adjustment moves the door up to 3mm in height, side, and depth after installation.
• Works on face-frame and frameless cabinets for versatility across cabinet construction types.

Where Half Overlay Gets the Job Done

Half overlay is the geometry for partial-overlap doors, especially pairs of doors that share a single center partition. Each door reaches partway across the cabinet side rather than covering it entirely, and the half crank arm on this hinge is what sets that position precisely. It handles both face-frame and frameless boxes, so a shop running mixed construction types can specify one hinge across both.

The 35mm cup bores into the back of the door and presses into the pre-drilled dowel holes, which means no cup screws on the door side. The hinge arm then connects to a Grass base plate on the cabinet, ordered separately. Use Grass plates matched to the Tiomos series; plates from other brands will not connect to this arm.

Steel Build With a Nickel Finish

The hinge is steel with a nickel finish. The integrated soft-close mechanism handles the work that protects the finish and the cabinet over years of daily use: the door never contacts the frame at speed, so the reveal stays clean and the cabinet box takes no repeated impact. Three-way adjustment means the hinge can be dialed back to square after the cabinet settles, without pulling the door off to start over.

Who This Hinge Suits

This is a practical fit for cabinet shops and contractors working face-frame or frameless kitchens, baths, and built-ins where a partial-overlay layout calls for damped closing. CNC-equipped shops benefit most from the dowel-press cup: it integrates into an automated boring sequence without adding a screwing step at the press. For doors thicker than 24mm, a thick-door hinge is the right move. Standard doors in the 16 to 22mm range are the sweet spot here, with the maximum door thickness rated to 24mm.

Common Questions

Quiet Doors, Clean Reveals, Fast Assembly

Specify this hinge when the project calls for half overlay doors that close softly, install quickly through a dowel-press bore, and stay square across face-frame and frameless cabinets alike.
