Grass Tiomos Concealed Hinge for Half Overlay Doors on Shared Partitions

The Grass Tiomos soft-close hinge in half overlay geometry is built for the two-door setup where a pair of doors share a single center partition, on both face-frame and frameless cabinets. Dowel mounting seats the hinge directly in the door bore, and integrated soft-close brings doors to a quiet stop every time.

Key Features

• Integrated soft-close damps the door over the final closing arc so it settles without impact.
• Half overlay, half crank arm positions each door at a partial overlay, the geometry two doors need when they share one partition.
• Dowel mount cup presses directly into the door's bored dowel holes with no cup screws, for fast, consistent CNC and production installs.
• 42mm boring pattern matches Grass Tiomos plate spacing — confirm your boring layout before ordering for replacements.
• Three-way adjustment provides up to 3mm of correction in height, side, and depth after the door is hung.
• Works on face-frame and frameless cabinets when paired with the appropriate Grass Tiomos base plate, sold separately.

Where the Half Overlay Setup Comes In

Half overlay is the call whenever two doors close on the same cabinet partition. Each door covers roughly half the partition thickness, and together they sit with a consistent reveal down the center. The half crank arm on this hinge carries that geometry precisely, without arms colliding in tight double-door runs. It also suits single partial-overlay doors where a full overlay would overreach the cabinet side. The 35mm cup bores into the back of the door, and the dowel mount version presses the cup into pre-bored dowel holes, so there are no cup screws to drive and the hinge registers the same depth every time.

Tiomos Build and Nickel Finish

The hinge body and arm are steel, finished in nickel. Tiomos is Grass's premium concealed platform, and the construction reflects it: the snap-on arm engagement connects to the Grass base plate quickly and releases without tools, and the soft-close damper is built into the hinge rather than added on. The three-way cam adjustment — height, side, and depth — lets you square doors up after the run is set, which protects the reveal as the cabinet settles over time. Maximum door thickness for this hinge is 24mm, which covers standard and slightly heavier doors without moving to a thick-door model.

Who Reaches for This Hinge

Cabinet shops running CNC equipment will find the dowel mount straightforward: the cup drops into pre-bored holes and the depth is set by the bore, not a screwdriver. It suits production runs of double-door base and wall cabinets on frameless boxes and face-frame carcasses alike. Contractors specifying partial-overlay kitchens and designers calling out Tiomos across a project reach for this hinge when the door layout puts two fronts on a shared partition. For frameless production with 5mm system holes and a faster plate mounting option, check whether the Tiomos screw-on or snap-on plate version better fits the shop's workflow. Either way, the base plate is a separate order: use Grass Tiomos plates only, as plates are brand and series specific and will not connect to another brand's arm.

Common Questions

Precise Placement, Quiet Close, Job Done

When the design puts two doors on one partition and the spec calls for a cushioned, silent close, this Tiomos hinge puts the geometry and the damping in one part, ready for production or custom work on either cabinet type.
