ANSI/BHMA Standards Authority:
- • ANSI A156.2-2019: Bored Locks and Latches (American National Standards Institute)
- • BHMA (Builders Hardware Manufacturers Association): Industry testing and certification body
- • UL 10C: Fire door hardware standards (safety compliance)
All measurements are industry-standard minimums. Local building codes may impose stricter requirements.
Door Material Compatibility Matrix
Wood Doors
Compatibility: 100%
- • All smart locks compatible
- • Easiest installation (standard drill bits)
- • Solid core > hollow core (stability)
Metal Doors
Compatibility: 90%
- • Requires cobalt/carbide drill bits
- • Slower drill speed (300 RPM)
- • Reinforced mounting plates recommended
Fiberglass
Compatibility: 85%
- • May crack - use masking tape
- • Verify lock weight < 4 lbs
- • Avoid over-tightening screws
Composite
Compatibility: 80%
- • Density varies by manufacturer
- • Foam core may need reinforcement
- • Verify with door manufacturer first
Glass Doors
Compatibility: 30%
