170-Degree Concealed Hinge for Full Overlay Doors

The Grass Nexis Impresso is a full overlay concealed hinge that opens to 170 degrees, bringing a cabinet door nearly flat with the cabinet side for maximum interior access. It mounts toollessly on both face-frame and frameless cabinets.

Key Features

• 170-degree opening angle swings the door almost completely flat, clearing nearly the full cabinet opening.
• Full overlay geometry positions the door to cover nearly the entire cabinet side, leaving a minimal reveal.
• Self-close spring draws the door shut over the final degrees of travel.
• Toolless arm engagement snaps the hinge onto the base plate without a screwdriver for fast door hanging and removal.
• Face-frame and frameless compatibility makes this hinge useful across both cabinet construction types.
• 35mm cup with straight arm fits the standard door bore and delivers the full overlay position.

Where Near-Flat Opening Changes the Job

Most concealed hinges open to 110 degrees, which works fine for everyday use. The 170-degree Nexis Impresso is the right call when the application actually needs that extra swing. Think of a cabinet built into a run where the door, if it stopped at 110 degrees, would block access to the corner of the box. Or an appliance garage where the door needs to fold back out of reach. Or any base or wall cabinet in an accessible design where full, unobstructed clearance to the opening matters. The 170-degree arc is a spec that solves a real spatial problem, and this hinge is built around it.

The hinge bores a 35mm cup into the door and clips to a Grass Nexis base plate mounted to the cabinet. The plate is a separate purchase, and it must be a Grass Nexis plate: Grass hinge arms do not connect to plates from other brands. The boring pattern here is 45 or 48mm, so confirm your cabinet's existing pattern before ordering for a replacement application.

Steel Build in a Nickel Finish

The hinge body is steel with a nickel finish. The self-close spring is integrated into this hinge, so no separate damper or closing device is needed, and no soft-close mechanism is involved. At 170 degrees, integrated soft-close is not offered in this hinge family, which is a hardware reality across the category: the geometry of the wide opening arc and a built-in damper are not compatible. The self-close spring pulls the door shut cleanly from a few degrees open. For installations where a cushioned, damped close is a priority, the correct choice is a narrower opening angle in the Nexis line.

Who Reaches for This Hinge

Cabinet shops fitting accessible kitchens and bathrooms, designers specifying corner or island cabinets where a swinging door needs to clear adjacent surfaces, and contractors working on commercial and multifamily projects where drawer and shelf access cannot be blocked by a door at mid-swing. It fits doors up to 26mm thick within the standard 16 to 22mm range for everyday stock, and up to 26mm for slightly thicker doors. Both frameless and face-frame boxes are supported, so it works across the common North American cabinet formats without sourcing a different hinge. The toolless arm engagement speeds installs when a run of doors is going up at once.

Common Questions

Maximum Clearance, Ready to Hang

When the design calls for a door that gets fully out of the way, the 170-degree Nexis Impresso delivers that clearance with a toolless install and self-close return on both face-frame and frameless cabinets.
