Concealed Hinge For Wide-Swing Overlay Doors

The Grass Tiomos soft-close hinge opens to 120 degrees with integrated damping, giving overlay doors on both face-frame and frameless cabinets a noticeably wider swing than the standard 110-degree configuration.

Key Features

• 120 degree opening angle clears the cabinet opening further for better access to deep shelves and full-width drawers.
• Integrated soft-close damps the door over the final degrees of travel so it settles quietly every time.
• Overlay straight arm positions the door to cover the cabinet side with a narrow reveal.
• Dowel mount presses the cup into pre-bored dowel holes for a screw-free, CNC-ready door-side installation.
• Three-way adjustment moves the door up to 3mm in height, side, and depth after installation.
• Fits doors up to 24mm thick, extending the usable range beyond the typical standard-hinge window.

Where the Extra Degrees Make a Difference

A 120-degree opening is the right call when a door swings toward a wall, an appliance, or a narrow aisle and the standard 110-degree swing leaves the opening feeling tight. Pantry cabinets, tall upper units beside a refrigerator, and island cabinets where someone is reaching across all benefit from the wider arc. The Tiomos platform handles both frameless and face-frame boxes, so it suits production shops running mixed cabinet types without stocking two different hinge families.

The 35mm cup bores into the door at the standard depth. On the cabinet side, a separate Grass base plate carries the arm. That plate is sold separately and must be a Grass plate matched to this hinge series. Plates from other brands will not connect to the Tiomos arm.

Steel, Nickel Finish, and a Dowel-Ready Cup

The hinge body is steel with a nickel finish. The dowel-mount cup skips the cup screws entirely: it presses into pre-bored 8mm dowel holes in the door, which is how CNC-equipped cabinet shops get consistent positioning run after run without driving individual screws at each hinge location. The soft-close mechanism is built into the hinge body, so no separate damper accessory is needed and the closing performance does not depend on an add-on staying in place.

Built for Production Shops and Precision Installs

Shops running line-bore equipment get the most out of this hinge. The dowel mount pairs naturally with a CNC boring pattern, and the Tiomos three-way adjustment handles the small door-position corrections that follow any install. The 24mm maximum door thickness also gives fabricators room to work with slightly thicker slab doors without switching to a thick-door hinge. For residential remodelers and finish carpenters, the wide opening and quiet close make it a strong choice on any cabinet where access or acoustics matter. If a project calls for the same Tiomos soft-close behavior at a narrower 110-degree swing, that configuration is available separately in the Tiomos family.

Common Questions

More Swing, Same Quiet Close

When a standard opening angle leaves the door in the way, this Tiomos hinge gives overlay doors the wider arc they need while keeping the soft, settled close that makes quality cabinetry feel right.
