Dowel Mounting And Production-Ready Soft-Close Fit

This Grass Tiomos concealed hinge brings integrated soft-close to overlay doors on both face-frame and frameless cabinets, with a dowel-mount cup that drops straight into pre-bored holes for a screw-free door-side installation.

Key Features

• Integrated soft-close damps the door through the final closing arc so it settles quietly without contact noise.
• Dowel mounting presses the cup into pre-bored dowel holes in the door, eliminating cup screws at the door side.
• 42mm bore pattern matches Grass Tiomos geometry for a direct, exact fit on Tiomos-bored casework.
• Overlay straight arm positions the door to cover the cabinet side with a consistent narrow reveal.
• Fits face-frame and frameless cabinets when paired with the appropriate Tiomos base plate, sold separately.
• Three-way adjustment at plus or minus 3mm height, 3mm depth, and 3mm side lets installed doors be dialed in after hanging.

Where Dowel Mounting Earns Its Place

In a CNC-driven shop or any production environment where doors are bored on a line-bore machine, dowel mounting removes the cup-screw step entirely. The hinge cup carries pre-installed dowels that press into the corresponding holes in the door, locking the hinge in place without reaching for a driver. On a run of cabinet doors that are bored consistently, that step savings compounds quickly. The 35mm cup seats in the door bore and the arm connects to a Grass Tiomos base plate on the cabinet side, which is a separate purchase matched to your cabinet construction and desired overlay position. Plates are Grass-specific: this hinge uses Tiomos plate geometry and will not pair with another brand's base plate.

Steel Build in a Nickel Finish

The hinge is steel with a nickel finish, the standard Tiomos platform material that holds up across production volumes. The 42mm bore pattern is the Grass specification for Tiomos and Nexis, so installers replacing or expanding an existing Tiomos installation will find this hinge drops into the existing prep without re-boring. Maximum door thickness for this hinge is 24mm, which covers standard cabinetry and slightly thicker doors that fall outside the typical 16-to-22mm window. For doors above 24mm, a thick-door hinge is the right choice.

The Right Hinge for Tiomos-Bored Production Work

This hinge is a natural fit for cabinet shops running Grass Tiomos throughout their line, particularly those boring doors on CNC equipment where the dowel holes are already part of the door-prep program. It also suits contractors and integrators specifying into an existing Tiomos installation, where bore-pattern matching matters for a clean replacement. The overlay straight arm works on both frameless box construction and face-frame cabinets, so it does not need to be treated as cabinet-type specific when quoting mixed jobs. Homeowners sourcing a direct replacement for a worn Tiomos hinge will find the dowel and bore specs here confirm the fit before ordering.
