It accommodates doors ranging from 0.75 inches to 1.375 inches thick and supports door weights up to 50 pounds. The hinge features a Delrin top pivot bearing and a bottom pivot cam that eliminate metal-to-metal contact, resulting in quiet operation and extended service life. Ample in-and-out lateral adjustment allows for precise door alignment during installation. Removable ramps are included, giving the installer control over door return behavior.\u003c\/p\u003e\u003cp\u003eThis hinge is suited for residential and light commercial cafe-style swinging door applications, including kitchen pass-throughs, saloon-style entries, and similar interior installations.

The door can be removed from the opening without detaching the hinge brackets, simplifying service and door swaps. Mounting screws are included.
