Concealed Long Arm Hinge for Half Overlay Doors With Dowel Mounting

The Grass Nexis is a self-closing concealed hinge sized for half overlay doors on both face-frame and frameless cabinets, with press-in dowel mounting for CNC and production environments where speed and repeatability matter.

Key Features

• Half overlay, half crank arm positions the door at a partial overlay, the standard geometry for two doors sharing a center partition.
• Self-close spring pulls the door shut automatically once it reaches the last few degrees of travel.
• Dowel mount presses the cup into pre-bored dowel holes in the door for a screwless, repeatable seating on the CNC line.
• 110 degree opening provides standard everyday access to cabinet interiors.
• Works on face-frame and frameless cabinets with the matching Grass Nexis base plate, sold separately.

The Right Geometry for Shared Partitions

Half overlay is the configuration for cabinet runs where two doors meet on a single center partition, each covering roughly half the panel rather than the whole side. The half crank arm places the door in that position precisely. The 35mm cup bores into the back of the door and the arm connects to a Grass Nexis base plate on the cabinet, ordered separately. Plates are Grass-specific, so only Nexis plates fit this hinge. The 45mm boring pattern means a replacement or upgrade job can drop into the same door holes as any hinge using the standard spacing.

Dowel Mount for Production Workflow

The hinge is plated steel in a nickel finish. What sets this version apart from the screw-mount Nexis is the dowel attachment: pre-bored dowel holes in the door accept the cup's press-in dowels without cup screws, which cuts the door-side step to a single press on a CNC-equipped line. The result is consistent seating across a run, with no driver needed at the door. On the cabinet side, the Nexis base plate screws or euro-mounts to the panel or stile in the standard way.

Built for Production Cabinet Shops

This hinge is a natural fit for cabinet shops running frameless or face-frame carcasses through a CNC cell, where pre-boring for dowel cups is already part of the program and screw-on cup attachment would slow the line. It also suits renovation work where an existing 45mm boring pattern is in place and a half overlay self-close replacement is needed. For projects where a cushioned, damped close is the requirement rather than a spring pull, the soft-close version of the Nexis is the one to specify instead. For doors thicker than about 22mm, a thick-door hinge with a deeper cup geometry is the right move.

Specify this hinge when half overlay doors and a CNC-ready dowel mount are the job, and the Nexis base plate handles the rest.
