Installation Notes

Installation is typically performed by carpenters or general contractors as part of interior door hanging. Power down any associated door hardware or alarm contacts before servicing. Use a sharp chisel to mortise the hinge leaf flush with the door edge and frame jamb for a proper fit. Follow local building codes for door hardware requirements on fire-rated or egress door assemblies.
