Installation Notes

Installation is performed by finish carpenters or experienced DIYers using standard door hardware tools including a screwdriver and latch installation kit. Power down any associated electronic access systems before servicing door hardware in smart-home applications. Verify backset measurement from the door edge to the center of the bore hole before installation to confirm proper fit. Do not overtighten mounting screws, as this may stress the rose or knob assembly.
