FAQ

What exactly does "Commercial Grade 2" mean for a door lock?

"Commercial Grade 2" is aspecific performance rating defined by ANSI/BHMA (American National Standards Institute / Builders Hardware Manufacturers Association) standards. It is not a marketing term. For locksets, it is governed by standards likeANSI/BHMA A156.13. A Grade 2 rating certifies that the lock has passed rigorous tests fordurability, security, and finish, positioning it as theoptimal balance between heavy-duty performance and cost-effectivenessfor many commercial and multi-family residential projects.

What are the key performance tests a Grade 2 lock must pass?

To earn a Grade 2 rating, locks are subjected to punishing tests, including:

  • Cycle Test: Minimum of 400,000 cycles of opening and closing, simulating years of high-frequency use.
  • Security Tests: Evaluates resistance to forced entry, including deadbolt strength (minimum 450 lbf impact), torque resistance on the lever/knob, and anti-pick/drill features on the cylinder.
  • Finish Tests: The surface coating must withstand salt spray corrosion tests and show minimal wear after repeated abrasion.

Where should I specify Grade 2 locks?

Grade 2 is the most widely specified grade for non-critical commercial and high-traffic residential applications. Typical use cases include:

  • Multi-Family Housing: Apartment unit entry doors, interior common doors.
  • Light Commercial: Office suites, hotel guest rooms, conference rooms, retail store back offices.
  • Institutional Buildings: Classroom doors, dorm rooms, administrative offices in schools.
  • High-End Residential: Main entry and interior doors where durability beyond basic builder-grade (Grade 3) is desired.
