To adjust the deadbolt length when installing your LOCKLY GUARD PGD728F Z Lockly Secure Plus Deadbolt, follow these steps: First, ensure the deadbolt slot aligns with the center of the door hole. The deadbolt is initially set to 2-3/4" (70mm). If required, adjust it to 2-3/8" (60mm). Remember to wear gloves to prevent pinching. To extend the deadbolt, insert a flat-head screwdriver into the slot and turn it clockwise. Finally, insert the deadbolt into the door edge hole, making sure the right side is up and the slot is vertical. Secure it with the two provided K screws. These steps will help you properly fit the LOCKLY GUARD PGD728F Z to your door.
