Grass Tiomos Concealed Hinge for Wide-Swing Half Overlay Doors

This Grass Tiomos concealed hinge brings a 120 degree opening angle and integrated soft-close to half overlay doors on face-frame and frameless cabinets, with a screw-on mount that delivers a solid mechanical connection to the cabinet.

Key Features

• 120 degree opening swings the door wider than the standard 110 degree, giving easier access to cabinet interiors.
• Integrated soft-close damps the door through the final closing arc so it settles quietly without slamming.
• Half overlay, half crank arm positions the door at a partial overlay, the geometry used where two doors meet on a shared center partition.
• Screw-on mount fastens the arm directly to the base plate for a firm, reliable connection that does not depend on pre-drilled system holes.
• Works on face-frame and frameless cabinets with the matching Grass base plate, sold separately.
• Three-way adjustment dials in height, side, and depth after the door is hung.

More Swing Where the Layout Calls for It

The 120 degree opening is the defining spec here. Where a standard 110 degree hinge suits most everyday cabinets, a 120 degree hinge opens wider, which matters in tight kitchens where a door swings toward an adjacent wall or appliance and every degree of clearance counts. It also benefits corner and peninsula cabinet runs where doors would otherwise block each other at full open. The half crank arm sets the door at a partial overlay, the configuration two doors use when they share a single center partition, so neither arm collides with the other on the inside of the cabinet.

The 35mm cup bores into the back of the door at a 12.6mm cup depth, and the arm connects to a Grass base plate on the cabinet. That plate is a separate purchase matched to your cabinet construction. A maximum door thickness of 24mm gives a bit more range than the standard 22mm window, so slightly thicker doors fit without moving to a dedicated thick-door hinge.

Steel Build, Nickel Finish, Screw-On Strength

The hinge body is steel finished in nickel. The screw-on arm-to-plate connection is the choice when a mechanical lock between arm and plate is preferred over a tool-free clip, or when the install environment does not have the pre-drilled system holes that tool-free mounting methods depend on. Once mounted, the three-way adjustment provides plus or minus 3mm in height, plus 3mm and minus 2mm in depth, and plus 3mm and minus 2mm in side travel, enough range to bring a run of doors to a consistent reveal without shimming or re-boring.

Where This Hinge Fits Best

Specify this hinge on half overlay door pairs sharing a center partition in face-frame or frameless cabinets where the extra door swing of 120 degrees is an advantage. It suits cabinet shops building custom runs with tight spatial constraints, designers specifying peninsula or corner kitchen layouts, and contractors swapping out hinges in an existing install where the wider swing resolves a clearance issue that a standard hinge does not. Because mounting uses screws rather than a clip or snap mechanism, it works on both 32mm system cabinets and non-system boxes alike. Use Grass base plates; plates are brand-specific and a plate from another manufacturer will not connect to this hinge.

Common Questions

Wider Access, Quiet Close, Solid Mount

When a half overlay layout needs more door swing and a cushioned close on a cabinet that calls for a screw-on connection, this Grass Tiomos hinge covers the job on both face-frame and frameless boxes.
