Angled Cabinet Hinge For Inset Doors on a 45-Degree Bay

This Grass Tiomos angled concealed hinge is built for inset cabinet doors on cabinets set at a 45-degree outward angle, such as diagonal corner base cabinets and angled bay fronts, on both face-frame and frameless construction.

Key Features

• +45-degree cabinet angle geometry fits doors mounted on a cabinet face that angles outward at 45 degrees.
• Inset door position seats the door flush inside the cabinet opening with an even reveal on all sides.
• Self-close spring pulls the door shut over the last few degrees of travel.
• Dowel mounting presses the cup into pre-bored dowel holes in the door without cup screws, suited to CNC and production environments.
• Three-way adjustment provides up to 3mm of movement in height, depth, and side to align the door after installation.
• Works on face-frame and frameless cabinets when paired with the matching Grass base plate, sold separately.

Where This Hinge Belongs

Diagonal corner cabinets present a specific problem: the cabinet face sits at a 45-degree angle to the wall, and the door needs a hinge geometry that accounts for that angle rather than fighting it. This hinge is built for that situation. The +45-degree arm geometry opens and closes the door correctly along the angled face, and the inset position sets the door flush inside the opening so the reveal reads evenly all the way around. Standard hinges built for a flat, square cabinet front will not produce a correct result here.

The 35mm cup bores into the back of the door, and the hinge arm connects to a Grass base plate mounted to the cabinet. That plate is sold separately and must be a Grass plate matched to this hinge series. For a door up to 24mm thick, this hinge covers the full standard-door range without moving to a thick-door hinge.

Steel Construction and a Nickel Finish

The hinge is plated steel in a nickel finish. Dowel mounting is the right choice for shops running CNC equipment: the cup carries pre-attached dowels that press into the bored holes in the door, removing the cup-screw step from a production workflow. The self-close spring handles the closing automatically once the door is released within its closing arc. Three-way adjustment covers 3mm of movement in each direction, which is enough to straighten a door after the cabinet is set and fastened.

Who Reaches for This Hinge

Cabinet shops producing diagonal corner units on a CNC line will find the dowel mounting and Tiomos build quality a natural fit. Contractors installing angled corner cabinetry on a remodel or custom kitchen need the correct angle geometry to get doors aligned without shimming. Designers specifying inset cabinetry on an angled bay run get the flush look they are after when the hinge geometry actually matches the cabinet angle. If the cabinet is a standard square front, this is the wrong hinge regardless of door style; for flat-front inset doors, a standard inset hinge is the right starting point.

The Right Geometry for a Diagonal Door

When the cabinet face is angled and the door sits flush inside it, this Tiomos hinge provides the geometry, inset position, and self-close action to make that door work correctly from day one.
