Installation Notes

Installation is performed by carpenters or general contractors as part of door hanging on interior frames. Power down any associated door hardware or alarm contacts before servicing. Use a sharp chisel to prepare or clean out the mortise pocket to the correct depth before seating the hinge leaf. Do not overtighten screws, as this can cause the hinge to bind or strip the mortise in wood frames.
