Nickel Thick Door Hinge for Inset Doors with a Controlled Swing

This Grass Tiomos hinge is built specifically for thick doors in an inset configuration, bringing a self-close spring and precise three-way adjustment to face-frame and frameless cabinets where standard hinges cannot seat correctly.

Key Features

• Thick door construction accommodates doors up to 36mm, where a standard hinge cup would not seat properly.
• Self-close spring pulls the door shut over the last few degrees of travel.
• 95 degree opening angle keeps the thick door clear of the cabinet front without binding.
• Inset geometry with full crank arm positions a flush door inside the cabinet opening with an even reveal.
• Dowel mount presses the hinge into pre-bored dowel holes for fast, accurate positioning in production environments.
• Three-way adjustment allows height, side, and depth correction after installation.

Built Around the Thick Door and the Inset Fit

Two things define this hinge's application: the door is thick, and it sits inside the opening rather than over it. A thick door, up to 36mm, requires deeper cup geometry so the cup seats fully without breaking through the door face. The inset configuration then demands that the door clear the cabinet opening precisely as it swings, which is why the 95 degree opening angle is the right call here rather than the wider standard swing. That restricted angle lets the thick door arc through the opening cleanly, without the edge catching the frame on the way out. The 35mm cup bores into the door, and the hinge arm connects to a separate Grass base plate on the cabinet, sold separately. Plates are Tiomos-specific and not interchangeable with other brands.

Steel Build and a Nickel Finish

The hinge body is steel with a nickel finish. Dowel mounting positions the cup precisely in the door bore without relying on cup screws, which matters on thick-door work where a slightly off-center cup creates alignment problems that compound across a run of doors. Three-way adjustment handles the fine work after the door is hung: height and side correction bring the reveal even, and depth adjustment seats the door flush in the opening. The self-close spring is a working spring, not a damper, so the door pulls shut on release but closes at the spring's pace rather than the installer's.

Where This Hinge Fits

This is the hinge for cabinet shops and installers working with slab or panel doors over the standard 22mm thickness, on frameless boxes or face-frame cabinets, where the design calls for a flush inset door. It suits production environments running CNC-bored doors, where dowel mounting drops the hinge into position repeatably. If the project calls for a damped, cushioned close rather than a spring pull, the soft-close Tiomos version in this series is the one to quote instead. For doors at standard thickness in an inset configuration, a standard-depth Tiomos inset hinge is the appropriate pick.

Common Questions

The Right Geometry for a Thick Inset Door

When the door is deep and the design calls for a flush fit inside the opening, this Tiomos hinge delivers the cup depth, the opening geometry, and the adjustment to do the job correctly from the first install.
