Grass Tiomos Impresso Free-Swinging Hinge for Overlay Doors on Face-Frame and Frameless Cabinets

The Grass Tiomos Impresso is a concealed overlay hinge with no spring and no damper, designed for cabinets where the door stays wherever it is positioned, including handle-less and push-to-open setups on both face-frame and frameless boxes.

Key Features

• Free-swinging motion means no spring pull and no damper, so the door holds any position without self-closing.
• 110 degree opening angle delivers standard everyday swing for overlay cabinet doors.
• Overlay straight arm positions the door to cover the cabinet side with a narrow reveal.
• Toolless snap-on arm engagement clips the hinge to the base plate without a screwdriver.
• Works on face-frame and frameless cabinets when paired with the matching Grass base plate.
• 42/45mm dual bore pattern accommodates the Grass Tiomos boring standard.

Where Free-Swinging Motion Earns Its Place

A free-swinging hinge is the right choice whenever the closing and holding work is done by something other than the hinge itself. Push-to-open systems need a hinge that will not fight the release mechanism, so a free-swinging hinge pairs with a touch-latch or push-to-open catch to keep the door closed and release it on demand. The same logic applies to doors that use a magnetic catch or a separate soft-close adapter added later. Because there is no built-in spring or damper, a free-swinging door also sits open at any angle without drifting, which is useful on appliance garages, display cabinets, and any run where the installer wants to control the closing behavior independently of the hinge. The 35mm cup bores into the back of the door in the standard way, and the arm connects to a separate Grass base plate mounted to the cabinet, ordered separately.

Tiomos Build and Finish

The hinge body and arm are steel in a nickel finish. The Tiomos platform is Grass's premium concealed line, and the Impresso carries that build quality into a free-swinging configuration: the snap-on arm engagement is the same tool-free connection used across the Tiomos range, and the three-way adjustment gives plus or minus three millimeters of movement in height, side, and depth after the door is hung. That range is enough to even out a full run of doors after installation and to compensate for cabinet settling over time. Maximum door thickness for this hinge is 24mm, which accommodates doors slightly above the standard 16 to 22mm window.

Who Should Specify This Hinge

Cabinet shops building handle-less kitchen runs on frameless boxes will reach for this hinge when push-to-open hardware is in the spec. Designers working on display cabinets or furniture pieces where door position matters and a self-closing spring would be a nuisance will find the free-swinging behavior useful. Contractors replacing hinges in an existing Tiomos installation should confirm the bore pattern before ordering, since Grass uses a 42/45mm dual bore that differs from the 45mm standard on other brands. Use Grass base plates only; Tiomos arms are not compatible with other brands' plates.

The Right Hinge for Doors That Close on Their Own Terms

When the closing behavior belongs to the catch or the push mechanism rather than the hinge, the Grass Tiomos Impresso free-swinging overlay hinge keeps the door out of the way and lets the rest of the system do its job.
