Grass Tiomos Concealed Hinge for Wide-Swing Overlay Doors

This Grass Tiomos soft-close hinge opens to 120 degrees and hangs overlay doors on face-frame or frameless cabinets, with a dowel mount and integrated soft-close built into the hinge body.

Key Features

• 120 degree opening angle swings the door wider than the standard 110 degree, giving better access to the cabinet interior.
• Integrated soft-close damps the door over the final closing arc so it settles quietly without slamming.
• Dowel mount presses the hinge cup into pre-bored dowel holes in the door for fast, screw-free door-side installation.
• Straight arm, overlay geometry positions the door to cover the cabinet side with a narrow reveal.
• 42mm boring pattern matches the Grass Tiomos bore spacing used across the Tiomos line.
• Three-way adjustment at plus or minus 3mm in height, side, and depth dials in an even reveal after the door is hung.

A Wider Swing for Better Cabinet Access

Where the standard 110 degree hinge opens a door to everyday working clearance, this 120 degree hinge takes it further, pulling the door back an additional 10 degrees so the full width of the cabinet opening is clear. That extra swing matters most on narrow cabinets, pantry pulls, corner-adjacent boxes, and anywhere a door that opens halfway blocks the interior. The 35mm cup seats in the door, and the arm connects to a Grass Tiomos base plate mounted to the cabinet. The base plate is a separate purchase matched to your cabinet construction and door position, and it is not included with this hinge. Use Tiomos-series plates only; Grass plates are not interchangeable with other brands.

Steel Build, Nickel Finish, and a Dowel-Mount Workflow

The hinge is steel with a nickel finish. On the door side, the dowel mount eliminates cup screws: the hinge presses into pre-bored 8mm dowel holes instead, which speeds up door-side installation on a CNC or production line and leaves a cleaner bore. The 35mm cup bores to a depth of 12.6mm. The hinge carries a maximum door thickness rating of 24mm, which takes it slightly beyond the standard 22mm window and accommodates slightly thicker overlaid doors without stepping up to a dedicated thick-door hinge.

Where This Hinge Fits the Work

Reach for this hinge when the job calls for a wider swing than 110 degrees and soft-close is still on the spec. It suits face-frame and frameless cabinets alike, making it useful across mixed-construction projects. Cabinet shops running CNC equipment will find the dowel-mount door side pairs naturally with pre-bored door programs. Remodelers and contractors who run Tiomos plates already have the compatible plate family on hand. For doors at the standard 110 degree swing, the 110 degree Tiomos soft-close version is the closer match. For doors thicker than 24mm, a thick-door hinge is the right call.

Common Questions

More Clearance, Quiet Close, Fast Install

Specify this hinge when the door needs to swing past 110 degrees, the close needs to be damped, and the door-side workflow benefits from a dowel press-in over cup screws.
