110-Degree Concealed Hinge for Flush Inset Doors on Face-Frame and Frameless Cabinets

The Grass Tiomos Impresso is a concealed long arm European hinge built for inset doors that sit flush inside the cabinet opening, with a self-close spring and toolless snap-on mounting, on both face-frame and frameless cabinets.

Key Features

• Inset overlay geometry seats the door flush within the cabinet opening with an even reveal on all sides.
• Self-close spring pulls the door shut automatically over the last few degrees of travel.
• 110-degree opening gives standard everyday swing clearance on flush-fitted inset doors.
• Toolless snap-on mounting engages the arm to the base plate without a screwdriver for fast door hanging and removal.
• 42/45mm dual boring pattern matches Tiomos plate boring and supports common production layouts.
• Three-way adjustment at plus or minus 3mm height, plus or minus 3mm side, and plus 3mm / minus 2mm depth fine-tunes the reveal after installation.

Precision Geometry for Flush Inset Work

An inset door doesn't sit over the cabinet face; it sits inside it, framed by a consistent gap on every edge. Getting that gap right means the hinge has to position the door exactly, and the Tiomos Impresso's full crank arm carries the geometry that holds an inset door in place through 110 degrees of swing. The 35mm cup bores into the back of the door at a 12.6mm depth, and the arm connects to a Grass base plate mounted to the cabinet side or frame. That plate is a separate purchase, matched to your cabinet construction. Because Tiomos plates use their own mounting pattern, use Grass plates specifically; plates from other brands will not connect to this hinge.

Steel Build with a Nickel Finish

The hinge body is steel finished in nickel. On inset cabinetry where the gap around the door is part of the visual design, the nickel finish keeps the hardware from drawing attention away from the reveal lines. The self-close spring is what protects the inset fit day to day: it draws the door to the closed position consistently rather than letting it rest ajar, which matters on a door whose gap tolerance is tight by design. Maximum door thickness is 24mm, covering standard and slightly thicker inset stock.

Where This Hinge Belongs

This is the hinge for cabinet shops, installers, and serious remodelers working inset doors on either frameless Euro boxes or traditional face-frame cabinets. The toolless snap-on arm speeds up installs across a run of doors, and the three-way adjustment handles the minor variation that comes with fitting flush doors in real cabinets. If the project calls for a damped, cushioned close rather than a spring pull, the soft-close Tiomos variant is the right choice for the same application. For overlay doors, an overlay-geometry Tiomos hinge is the correct pick instead.

An Even Reveal, Every Door, Every Time

Specify the Tiomos Impresso when the job calls for flush inset doors that close on their own, sit square in the opening, and stay that way, on face-frame or frameless cabinets alike.
