Grade 2 & Grade 3
These are certification standards ratings developed for the U.S. that provide an easy reference to the strength, security, and durability of a lock. Lock rated as Grade 3 is not as strong as a lock rated at Grade 2. For a lock to pass Grade 3 standards it must endure 200,000 cycles of opening and closing, whereas a Grade 2 lock must pass 400,000 cycles. The lock's strength is also tested in increased severity as applied to forced entry through a door.
