The American Nation Standards Institute (ANSI) grading system for deadbolts was developed by the Builder's Hardware Manufactures (BHMA). This grading system ranges from 1 (the highest grade) to 3 (the lowest grade). It factors in longevity of the lock, toughness, and latch length.
Similarly one may ask, what are the different grades of locks?
There are three different lock grades, which include:
- ANSI Grade 1- This is a heavy-duty commercial security lock.
- ANSI Grade 2- This is a high residential security or low commercial grade.
- ANSI Grade 3 - This is a basic residential security lock that meets the lowest acceptable quality standards for locks by the ANSI.
Beside above, how are door locks graded?
This is the highest level of ANSI grades for door locks. To earn this grade, a door knob must withstand 800,000 cycles, six door strikes and a 360-pound weight test. A deadbolt rated as Grade 1 must withstand 250-thousand cycles and 10 door strikes with a hammer.
Grade 1 not only meets commercial building requirements, it also provides the best security available against vandalism and heavy usage. Grade 2 meets light commercial requirements and exceeds residential building requirements. These locks are adequate for lighter duty doors where security is less of an issue.
