Deadbolt locks keep homes, offices, and jobsites secure. They feature a solid, retractable bolt that slides into a corresponding mortise in a door frame when the door is closed and the cylinder is turned. Deadbolts can be used in combination with standard doorknob locksets to add an extra layer of security.
