Wide-Angle Concealed Hinge for Half Overlay Doors

This Grass Tiomos concealed hinge brings 155-degree wide-angle opening and integrated soft-close to half overlay doors on both face-frame and frameless cabinets, with a dowel-mount cup for CNC and production environments.

Key Features

• 155-degree opening angle swings the door nearly flat for maximum access, the widest angle available with integrated soft-close in the Tiomos line.
• Integrated soft-close damps the door over the final closing arc so it settles quietly without slamming.
• Half overlay, half crank arm positions the door at a partial overlay, suited to pairs of doors sharing a center partition.
• Dowel-mount cup presses into pre-bored dowel holes for fast, screw-free installation in CNC-bored doors.
• Three-way adjustment provides 3mm of correction in height, side, and depth after the door is hung.
• Works on face-frame and frameless cabinets when paired with the matching Grass Tiomos base plate, sold separately.

Where the Wide Angle Does Real Work

A 155-degree opening matters most where access counts: pantry pulls, corner cabinets, and tall doors that need to swing past 110 degrees to clear adjacent walls or appliances. At 155 degrees the door folds back to nearly flat against the cabinet side, so nothing blocks the opening. That range tops out the Tiomos line for soft-close, meaning this hinge delivers the widest swing that still comes with a quiet, damped close. The half crank arm positions each door at a partial overlay, the geometry two doors use when they share a single center stile or partition. The 35mm cup bores into the door, and the arm connects to a Grass Tiomos base plate mounted to the cabinet, which is ordered separately. Plates are Grass-specific and not interchangeable with other brands.

Steel Construction with a Production-Ready Mount

The hinge body is steel in a Nickel finish. The dowel-mount cup carries pre-attached dowels that press directly into the bored dowel holes in the door, bypassing the cup screws used on screw-on versions. In a CNC workflow where doors come off the machine with consistent boring, dowel mounting keeps the install moving: no cups to screw down, no alignment step per hinge. The 35mm cup sits at a 10mm depth. For doors up to 32mm thick, this hinge seats correctly without switching to a thick-door series.

Who Should Specify This Hinge

Cabinet shops running CNC-bored doors in production volume are the primary fit here. The dowel mount is built for that workflow, and the Tiomos snap-on arm engagement means hanging a door is fast once the plates are set. Designers and contractors specifying partial-overlay kitchens where wide clearance is a priority, such as pantry walls or appliance garages, get the added benefit of the 155-degree swing with soft-close intact. The hinge works on both face-frame and frameless boxes, so it covers the range of construction types common in residential and light-commercial work. For standard everyday cabinetry where 110 degrees is enough, the standard-angle Tiomos is the simpler pick; specify this one when the wider arc is worth calling out.

Wide Clearance, Quiet Close, Ready for the Production Floor

Specify this Tiomos hinge when the job calls for half overlay doors that swing wide, close quietly, and install fast in a CNC-bored workflow on either frame style.
