Dowel-Mount Soft-Close Hinge for Half Overlay Doors at 120 Degrees

This Grass Tiomos hinge is built for half overlay doors on face-frame and frameless cabinets, using a dowel-mount cup for a press-in, screw-free installation at the door, with integrated soft-close and a generous 120 degree opening angle.

Key Features

• 120 degree opening angle swings the door wider than the standard 110 degree for better interior access.
• 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 for partial overlay, the geometry two doors use on a shared center partition.
• Dowel-mount cup presses into pre-bored dowel holes in the door with no cup screws required.
• Works on face-frame and frameless cabinets when paired with the appropriate Grass base plate, sold separately.
• Three-way adjustment dials in height, side, and depth after the door is hung.

Where the 120 Degree Opening and Dowel Mount Earn Their Place

The standard 110 degree opening covers everyday cabinet use, but a wider swing matters when the interior space is deep, when the cabinet sits at eye level and full access is the priority, or when two adjacent doors need extra clearance as they open simultaneously. At 120 degrees, this hinge gives a noticeably wider path into the box without stepping up to a specialty wide-angle product.

The dowel-mount cup is the right choice in CNC and production environments where the door comes off the machine with pre-bored 8mm dowel holes already positioned. The cup presses into those holes cleanly and holds without cup screws, keeping the door-side installation fast and consistent across a full run. The 35mm cup seats in a standard bore, and the 45mm boring pattern matches the Grass plate layout.

Half overlay geometry places this hinge on doors that cover the cabinet side by a partial amount rather than the full width, most commonly where two doors share a single center partition. The half crank arm creates the offset that keeps paired doors from colliding when they open together. A separate Grass base plate is required and sold separately; use a Grass plate matched to the Tiomos series, as plates are not interchangeable across brands.

Steel Build in a Nickel Finish

The hinge body is steel with a nickel finish. Maximum door thickness is 24mm, which extends slightly beyond the standard 22mm window and accommodates solid wood doors and thicker slab fronts without moving to a dedicated thick-door hinge. The three-way adjustment range of plus 3mm and minus 2mm in each direction gives enough play to true up a full run of doors after installation, correcting for cabinet variation and door drift over time.

The Right Specification for Production and Custom Work

Cabinet shops running CNC equipment get the most from this hinge: the dowel mount aligns with a pre-programmed boring pattern, the snap-on Tiomos arm clips to the plate without tools, and the soft-close finish keeps every door quiet regardless of who closes it. Custom builders and contractors working on face-frame kitchens or frameless boxes both find a fit here, since this hinge serves either cabinet construction when the correct Grass plate is specified. For doors on a single run that vary between full overlay and half overlay positions, the half overlay version is for the shared-partition doors; full overlay hinges handle the outside doors on the same cabinet run.

Specify this Tiomos hinge when a half overlay layout, a 120 degree swing, and a press-in dowel mount combine to fit the job, and every door in the run needs to close without a sound.
