155-Degree Concealed Hinge for Full Overlay Doors With Wide-Swing Clearance

This Grass Tiomos soft-close hinge opens to 155 degrees, delivering wide-swing clearance on full overlay doors across both face-frame and frameless cabinets, with a dowel-mount cup and integrated soft-close damping.

Key Features

• 155-degree opening angle swings the door nearly flat for maximum interior access in tight spaces.
• Integrated soft-close damps the door over the final closing arc so it settles quietly without slamming.
• Full overlay straight arm positions the door to cover nearly the entire cabinet side, leaving a narrow reveal.
• Dowel-mount cup presses into pre-bored dowel holes for a fast, screw-free door-side installation in production environments.
• 35mm cup bores into standard doors up to 32mm thick, broadening the range beyond the standard 16-to-22mm window.
• Three-way adjustment of plus or minus 3mm in height, side, and depth for precise door alignment after install.

Wide Swing Where Interior Access Matters

At 155 degrees, this hinge opens the door close to flat against the cabinet side, a meaningful advantage wherever adjacent walls, appliances, or corner layouts make it hard to reach the full cabinet interior with a standard 110-degree swing. The geometry suits base cabinets next to refrigerators, tall units near a wall, and any run where the installer needs the door out of the way. The hinge works on both frameless cabinet boxes and face-frame cabinets, so one part number covers either construction type. A matching Grass base plate, sold separately, completes the installation on the cabinet side. Use Grass plates only; the snap-on engagement is Grass-specific and will not connect to another brand's plate.

Steel Build, Dowel Efficiency, Quiet Closing

The hinge is steel in a nickel finish. The dowel-mount cup carries pre-attached dowels that press into bored dowel holes in the door, eliminating cup screws and speeding up the door-side step in CNC and production shops. Once the door is hung, the integrated soft-close damper takes over at the end of each close, pulling the door in and slowing it before contact. That combination of fast mounting and a quiet, controlled close is what keeps this hinge in volume rotation on commercial and multi-unit projects. Three-way adjustment gives the latitude to bring doors to an even reveal after the cabinet is set, without shimming or re-boring.

Production Shops, High-Access Installs, and Thick-Door Work

This hinge earns its place in shops running dowel-bored doors at volume, and on installs where a 155-degree opening is part of the design or site requirement. The 32mm maximum door thickness extends its range to thicker slab doors and some face-frame applications that push past the standard 22mm limit. Designers specifying accessible kitchens or open-reach commercial cabinetry will find the wide angle relevant. Cabinet shops ordering for a full run benefit from the dowel mount's speed on the door side. A separate mounting plate is required and sold separately; pair with the Grass plate series matched to your cabinet construction.

Specify this hinge when the job calls for wide-swing access, a soft-close finish, and dowel-speed on the door side, across face-frame or frameless construction.
