Concealed Hinge for Half Overlay Push-to-Open and Handle-Free Applications

The Grass Nexis is a free-swinging, half overlay concealed hinge designed for doors that share a center partition or sit at a partial overlay, on both face-frame and frameless cabinets. With no spring and no damper, it stays where you leave it, making it the right starting point for push-to-open setups and any application where door motion is handled by a separate mechanism.

Key Features

• Free-swinging motion means the door holds at any position with no spring pull and no soft-close resistance.
• Half overlay, half crank arm positions the door to cover the cabinet side partially, the geometry suited to two doors meeting on a shared partition.
• 100 degree opening angle gives practical access while keeping the swing controlled in tighter runs.
• Dowel mount cup presses into pre-bored dowel holes for a fast, screw-free door-side installation.
• Works on face-frame and frameless cabinets when paired with the matching Grass Nexis base plate, sold separately.
• 35mm cup in nickel-finish steel fits the standard door bore and coordinates with Nexis-series hardware.

Where Free-Swinging Half Overlay Makes Sense

A free-swinging hinge stays open at whatever angle you set it. That is the right behavior for handle-less fronts using a push-to-open mechanism, where a self-close spring would fight the latch, and for applications where a separate soft-close adapter or integrated cabinet system controls the door motion. The half crank arm positions each door to cover about half the cabinet side, the standard setup when two doors share one center partition and both need room to clear each other. At 100 degrees of swing, the hinge delivers solid access without pushing into adjacent doors or a wall.

The dowel mount on the cup side speeds the door-side step in a production or CNC workflow: the cup dowels press straight into pre-bored holes in the door without cup screws, keeping line speed up. A matching Grass Nexis base plate mounts to the cabinet side and is sold separately. Use Grass Nexis plates with this hinge; plates are brand and series specific and will not transfer from another manufacturer.

Steel Build, Nickel Finish

The hinge is steel with a nickel finish. Nexis is Grass's value-oriented concealed line, built for consistent performance across production runs rather than premium single-unit specifications. The 35mm cup at 11.8mm depth seats cleanly in a standard door bore. Note that the boring pattern is 48mm, not the 45mm common on many Euro hinges, so confirm your boring setup matches before running a batch.

Right Fit for This Hinge

This hinge belongs on standard-thickness doors in the 16 to 22mm range. It is a natural pick for cabinet shops building handle-less fronts with push-to-open hardware, for multi-unit projects where a proven value-line hinge keeps costs predictable, and for any run where door motion is managed externally rather than by the hinge itself. For doors that need a spring pull to stay shut on their own, a self-closing Nexis variant is the better call. For a cushioned, quiet close, look to the soft-close versions in this series.

Common Questions

Keep the Job Moving on Every Handle-Free Front

Specify this hinge when the design calls for half overlay doors on a push-to-open or externally controlled system, and you need a reliable, production-ready concealed hinge that runs cleanly across face-frame and frameless cabinets alike.
