Installation Notes

Installation is typically performed by finish carpenters or general contractors using a chisel, drill, and screwdriver. Mortise the hinge leaf flush with the door edge and jamb face before fastening to prevent binding. Verify door weight and frequency of use are within the hinge load rating before installation. Remove the door from its opening before servicing or replacing existing hinges to prevent injury.
