Grass Tiomos Concealed Hinge for Dowel-Mounted Overlay Doors

This Grass Tiomos self-close hinge brings the Tiomos platform to face-frame and frameless cabinets through dowel mounting, setting overlay doors to a standard 110-degree swing with a spring-pull close.

Key Features

• Self-close spring pulls the door shut over the final degrees so it does not stand open.
• Dowel mounting presses the cup into pre-bored dowel holes in the door for a screw-free door-side attachment.
• 42mm boring pattern matches the Grass Tiomos bore spacing, which differs from the 45mm pattern common on other brands.
• Overlay straight arm positions the door to cover the cabinet side with a narrow reveal.
• Three-way adjustment dials height, side, and depth independently after mounting.
• Works on face-frame and frameless cabinets when paired with the matching Grass Tiomos base plate, sold separately.

Where Dowel Mounting Earns Its Place

CNC shops and production lines running Grass Tiomos boring patterns reach for this hinge when the door is pre-bored for dowels rather than cup screws. The dowel-mount cup presses directly into the door's bored dowel holes, eliminating the screw step on the door side and keeping the line moving. The arm then snaps onto the base plate mounted to the cabinet. That plate is a separate item, Grass Tiomos plates are specific to this platform, and a plate from another brand will not connect.

The 42mm boring pattern is the detail to confirm before ordering. Tiomos uses 42mm center-to-center hole spacing on the cabinet side, not the 45mm pattern common to many other concealed hinges. If existing holes in the cabinet are bored at 45mm, this hinge will not align to them without re-boring.

Steel Build in a Nickel Finish

The hinge body is steel with a nickel finish. The straight arm carries the overlay geometry, and the three-way adjustment range gives enough movement to bring doors into alignment after the cabinet is set. Maximum door thickness is 24mm, so it handles standard doors and doors slightly over the 22mm typical range without moving to a dedicated thick-door hinge. The 35mm cup seats at 12.6mm depth in the door.

The Right Fit for Tiomos Production Work

This hinge suits cabinet shops running Grass Tiomos systems where dowel boring is standard, and remodelers replacing existing Tiomos dowel-mount hinges on face-frame or frameless boxes. If the project calls for a cushioned, damped close rather than a spring pull, the Tiomos soft-close version is the right choice. For doors already bored at 45mm from a different brand's layout, use a hinge matched to that bore pattern instead.

Production-Ready, Platform-True

Specify this hinge when the job runs Grass Tiomos boring, the door side is pre-bored for dowels, and a reliable self-close close is what the application needs.
