Grading System FAQs

Q: Which grade of door lock should I buy for my home?


We recommend a Grade 2 lock with a 1-inch bolt. All entry doors, including front, rear, and side entrances should have deadbolts.

Q: What is the difference between Grade 1, Grade 2, and Grade 3 door hardware?


The ANSI grading system denotes the durability and security level of the lock.

  • Grade 1: These commercial-quality locks are recommended for heavily trafficked commercial buildings.
  • Grade 2: These locks are recommended for heavy residential and light commercial use.
  • Grade 3: These locks are recommended for standard residential security.
