Installation Notes

Installation is typically performed by a finish carpenter or experienced installer using standard hand tools. Power down any connected smart home systems or door sensors before beginning hardware replacement. Follow the door prep dimensions supplied with the hardware set and verify door thickness before ordering. Do not overtighten rosette mounting hardware, as concealed fastener designs rely on proper seating of the interior trim plate to maintain alignment.
