Grass Tiomos Concealed Hinge For Wide-Open Overlay Doors

The Grass Tiomos Impresso is a self-close concealed hinge for overlay doors on both face-frame and frameless cabinets, opening to 120 degrees for noticeably wider access than the standard 110-degree hinge.

Key Features

• 120-degree opening swings the door further back for easier access to deep shelves and corner runs.
• Self-close spring pulls the door shut automatically over the last few degrees of travel.
• Toolless snap-on arm connects to the base plate without a screwdriver for fast door hanging and removal.
• Works on face-frame and frameless cabinets when paired with the matching Grass plate, sold separately.
• Three-way adjustment moves the door up to 3mm in height, side, and depth to dial in an even reveal.
• 42/45mm dual bore pattern fits both Grass-bored and standard 45mm cabinets.

Where the Extra Swing Angle Earns Its Place

At 120 degrees, this hinge opens the door about ten degrees past the everyday standard, which makes a real difference on tall pantry cabinets, deep base units, and wall runs where adjacent doors or appliances are not directly in the way. The extra clearance lets a standing person reach the back of a shelf without the door pressing against their arm, and it keeps neighboring doors from limiting access on adjacent cabinets.

The 35mm cup bores into the door at 12.6mm deep, and the arm connects to a Grass base plate mounted to the cabinet side or face-frame stile. That plate is a separate purchase and must be a Grass plate matched to this series. Plates from other brands will not connect to the Tiomos arm.

Steel Build in a Nickel Finish

The hinge body is steel with a nickel finish. The Tiomos Impresso carries the snap-on arm engagement Grass uses across the Tiomos platform, so the arm releases from the plate without tools when a door needs to come down for finishing or painting. The self-close spring draws the door to latch on its own; this is not a soft-close hinge and does not include a damper. For a cushioned, quiet close, the soft-close version of this series is the one to spec instead.

Right for Volume Work and Precise Installs

This hinge suits cabinet shops, installers, and remodelers who need a reliable wide-angle hinge with toolless door removal on either cabinet construction type. The dual 42/45mm bore pattern means it drops into Grass-bored cabinets and into shops running the standard 45mm pattern. Maximum door thickness is 24mm, so it handles doors slightly above the standard 22mm window without stepping up to a dedicated thick-door hinge. For doors over 24mm, a thick-door hinge is the right call.

More Access, Faster Installs, on Any Box

Specify this hinge when a wider door swing makes the space more usable and toolless arm removal keeps the job moving on both frameless and face-frame work.
