Grading System FAQs
Q: Which grade of door lock offers the best security for my home?
A:
Industry experts agree that a Grade 2 NightWatch® deadbolt with a 1' bolt is the ideal choice for home security. For maximum protection, deadbolts are recommended on all entry doors including front, rear, and side entrances as well as any walk-in doors leading to your garage.
