Wide Swing and Soft-Close in a Half Overlay Fit

This Grass Tiomos hinge opens to 155 degrees with integrated soft-close, sized for half overlay doors on both face-frame and frameless cabinets. It mounts by screw directly to a compatible Grass base plate, sold separately.

Key Features

• 155 degree opening angle swings the door nearly flat, clearing deep shelves and corner-adjacent boxes.
• Integrated soft-close damps the door over the final arc so it settles without impact.
• Half overlay half crank arm positions two doors correctly on a shared center partition.
• Screw-on mounting fastens the arm to the base plate with screws for a fixed, secure connection.
• Three-way adjustment moves the door up to 3mm in height, depth, and side independently after installation.
• Works on face-frame and frameless cabinets when paired with the matching Grass plate for each construction type.

Where a 155 Degree Swing Earns Its Place

Most cabinet hinges top out at 110 degrees, which is enough for everyday reach-in access. A 155 degree hinge is the right call when the door needs to travel much farther: pulling fully open alongside a refrigerator run, clearing the adjacent wall in a tight galley, swinging back along the cabinet face on an island, or giving unobstructed access to a deep pantry column. At that arc the door sits nearly parallel to the cabinet side, out of the way rather than in it.

The half crank arm positions the door at a half overlay, the geometry used when two doors share a single center partition and each needs to cover only its half of the opening. The 35mm cup bores into the back of the door at a standard depth of 10mm. The hinge then connects to a Grass base plate on the cabinet, ordered separately. Plates are specific to the Tiomos series and must be matched to your cabinet construction, frameless or face-frame.

Steel Build with a Nickel Finish

The hinge body is steel with a nickel finish. Tiomos is Grass's premium concealed line, and the soft-close mechanism is built into the hinge rather than added on. The three-way adjustment range of plus or minus a few millimeters in each direction gives installers room to bring a row of doors to a consistent reveal after the plates are set. The maximum door thickness supported is 32mm, which accommodates heavier solid-wood doors beyond the standard 16 to 22mm window.

Who Reaches for This Hinge

Cabinet shops and contractors who spec wide-angle hinges tend to have a specific reason: a floor-to-ceiling pantry that needs the door fully clear, a wall-adjacent box where a standard swing clips the trim, or a designer detail that calls for doors that disappear when open. This hinge handles those conditions with the soft-close and adjustment range of the Tiomos platform. It suits face-frame shops running traditional American cabinetry and frameless operations in equal measure, provided the correct Grass plate is used for each. For doors that sit fully closed most of the time and only need a standard swing, a 110 degree version covers less arc but is easier to source at volume.
