A stud projects from the back of each hinge leaf to prevent the door from being forced open. The mounting holes form an industry-standard half-moon shape. The hinge leaves fit into cutouts (mortises) to mount flush with door and frame edges. Use this hinge on doors with or without a door closer. It has concealed bearings to open and close doors smoothly. Also known as a hospital-tip hinge, the top and bottom of the hinge pin are cut on an angle. The pin is nonremovable to provide additional tamper resistance. Capacity is based on three hinges per door with a maximum door size of 7 ft. Ht. × 3 ft. Wd. × 1 3/4" Thick.
