Installation Notes

Installation should be performed by a licensed locksmith or qualified commercial door hardware technician in accordance with local building codes and the door manufacturer's specifications. Verify door thickness and backset dimension before installation to confirm proper bolt projection and strike alignment. Remove all door hardware and ensure the door is secured in a stable position before drilling or chiseling the strike mortise. Do not over-drive mounting screws, as this can crack the door stile or misalign the bolt throw.
