Wide-Swing Concealed Hinge for Half Overlay Doors

This Grass Tiomos self-close hinge opens to 155 degrees and hangs half overlay doors on both face-frame and frameless cabinets, using a dowel cup mount for precise, screw-free seating in the door.

Key Features

• 155 degree opening swings the door nearly flat to the cabinet side, giving maximum interior access.
• Half overlay, half crank arm positions the door over part of the cabinet side, the geometry for two doors sharing a center partition.
• Self-close spring draws the door shut over the last few degrees of travel.
• Dowel cup mount presses into bored dowel holes in the door with no cup screws, for fast, repeatable CNC-ready installation.
• 42mm bore pattern matches the Grass Tiomos boring layout, standard for this platform.
• Three-way adjustment moves the door up to 3mm in height, side, and depth after the plate is set.

Where the 155 Degree Swing Earns Its Place

A 155 degree opening is the widest swing available in the Tiomos self-close family, and the practical difference is real: the door swings back close to the cabinet side rather than stopping at a right angle, so pots, shelves, and wide drawers clear without having to hold or prop the door out of the way. It suits corner runs and any cabinet where a standard 110 degree swing creates an obstacle in a tight kitchen or utility space. The half crank geometry places the door at a partial overlay, so this hinge fits both single partial-overlay doors and the paired-door configuration where two doors share one center partition. The 35mm cup bores into the door, and the arm snaps to a matching Grass Tiomos base plate mounted to the cabinet, which is ordered separately.

Tiomos Build and Dowel Precision

The hinge is plated steel in a nickel finish, consistent with the Tiomos platform's production-grade construction. The dowel cup mount is the detail that separates this version from screw-cup variants: the cup carries pre-attached dowels that press into bored holes, eliminating cup screws and making it the natural choice for CNC-drilled doors where repeatability matters. Adjustment is dialed in from the arm: height, side, and depth each move within a 5mm total range, enough to bring a full run of doors to an even reveal after the cabinet is in place.

Shops Running Production and Installers Fitting Corners

This hinge fits two types of buyers well. For cabinet shops running CNC-drilled face-frame or frameless boxes, the dowel mount drops in without cup screws and keeps the line moving. For installers fitting corner cabinets or tight kitchen runs, the 155 degree swing removes the door from the traffic path in a way a standard-angle hinge does not. The hinge works on both face-frame and frameless boxes, so it carries across a mixed project without switching specs. Note that the Grass Tiomos bore pattern is 42mm, not the more common 45mm, so replacement work requires confirming the existing bore before ordering. For doors thicker than 32mm, a thick-door hinge is the correct pick.
