Grass Tiomos Concealed Hinge for Wide-Swing Overlay Doors

This Grass Tiomos self-close hinge opens overlay doors to 155 degrees, delivering near-flat clearance on face-frame and frameless cabinets where everyday access is not enough and a full, unobstructed swing is needed. It mounts via pre-attached dowels for fast, screw-free door installation.

Key Features

• 155 degree opening angle swings the door nearly flat against the cabinet side for maximum interior access.
• Self-close spring draws the door shut automatically over the last few degrees of travel.
• Overlay geometry positions the door to cover the cabinet face on both face-frame and frameless boxes.
• Dowel mounting presses the cup into pre-bored 8mm dowel holes in the door, no cup screws needed.
• 42mm boring pattern matches Grass Tiomos system spacing in the door.
• Three-way adjustment moves the door up to 3mm in height, side, and depth after hanging.

Where the 155 Degree Opening Earns Its Place

A standard 110 degree hinge leaves roughly a third of the cabinet side blocked by the open door. At 155 degrees, the door folds back far enough that it barely extends past the cabinet box, which matters in tight kitchens, accessible-design installations, and anywhere a wheelchair, appliance, or adjacent wall would catch a door at a standard swing. This hinge is also the right answer when a designer wants visible access to the full cabinet interior without the door sitting in the way. The 35mm cup bores into the door, and the hinge arm connects to a Grass Tiomos base plate on the cabinet side, which is sold separately and must be a Grass Tiomos plate. For doors up to 32mm thick, this hinge handles the load; for anything over that, a thick-door hinge is the correct tool.

Steel, Nickel Finish, and the Tiomos Snap Connection

The hinge body is steel with a nickel finish. The Tiomos snap-on arm engages the base plate with an audible click and releases for door removal without tools, a practical feature in any shop that hangs and re-hangs doors during a full cabinet run. The dowel mounting on the door side completes the picture: the pre-attached dowels press into bored holes and hold the cup without screws, which speeds up door-side installation in CNC and production environments. Three-way adjustment at plus or minus 2 to 3mm in each direction gives enough range to align doors evenly after the cabinets are set.

Who Reaches for This Hinge

Cabinet shops and contractors specifying Grass Tiomos hardware will recognize this hinge as the wide-angle option within the Tiomos line for face-frame and frameless work alike. It suits accessible kitchens, corner runs where a neighboring door or wall limits how far a standard-swing door can travel, and any project where the architect or designer has called out a 155 degree hinge specifically. Homeowners replacing existing Tiomos hardware at this angle will find it matches the bore pattern and plate system already in the cabinet. Because this hinge is self-close, the door pulls shut on its own but without a soft-close damper. For a cushioned, quiet close at a wide swing angle, note that 155 degrees is actually the widest opening at which soft-close is available in the Tiomos line, so a Tiomos soft-close version at this angle would be the next step up.
