BROOKLYN, NY — March 31, 2026 — is highlighting common specification mistakes that contractors and facility managers encounter when selecting commercial door hardware. According to the company, many hardware failures stem not from product defects but from specification errors, including incorrect grading, incompatible components, or code compliance oversights.
Most commercial door hardware failures are not product failures but specification issues. Selecting the wrong grade for high-traffic openings, adjusting closers beyond ADA limits, or installing non-UL-listed exit hardware on fire-rated doors can lead to inspection violations, insurance complications, and costly retrofits. These issues occur because commercial door hardware selection requires balancing performance standards, life-safety codes, and system compatibility requirements.
Facility managers, general contractors, and specifiers sourcing National Lock Supply’s commercial door hardware often need to consider three key frameworks simultaneously: ANSI/BHMA performance standards, life-safety and building codes, and system-level compatibility requirements. Errors in any of these areas can create long-term operational challenges and additional costs.
Understanding ANSI/BHMA Performance Standards
The ANSI/BHMA A156 standards, maintained by the Builders Hardware Manufacturers Association, define performance requirements across multiple hardware categories. Grade classifications are determined through controlled testing, including cycle endurance, torque resistance, impact resistance, and finish durability.
For example, Grade 1 mortise locks are tested to complete up to one million cycles, while Grade 2 locks are tested for 800,000 cycles. This difference can translate into years of service life in high-traffic environments. As a result, Grade 1 hardware is commonly specified for main entries, stairwells, classrooms, and egress corridors, while Grade 2 hardware may be suitable for light-use interior openings.
Code Requirements and Compliance Considerations
Performance standards operate alongside building and life-safety codes, including NFPA 101 Life Safety Code, NFPA 80, the International Building Code, and ADA accessibility requirements. These frameworks define how hardware must perform in specific building environments.
Examples include:
- Egress doors must open without keys or special knowledge
- Fire-rated door hardware must be UL-listed
- ADA-compliant doors must meet opening force limits
- Hardware must be operable with one hand on accessible routes
One common challenge involves balancing ADA opening force requirements with fire-door latching requirements. In some cases, low-energy power operators may be used to maintain both accessibility and fire safety compliance.
Commercial Door Openings as Integrated Systems
Commercial door openings function as integrated systems where each component must work together. Locks, exit devices, hinges, closers, and electrified hardware must be compatible and properly rated for the specific door and building requirements.
Common hardware categories include:
- Cylindrical locks for standard interior openings
- Mortise locks for high-security applications
- Exit devices for assembly and educational facilities
- Door closers matched to door weight and location
- Ball-bearing hinges for high-traffic doors
When hardware is specified individually without considering compatibility, installation issues often arise.
Common Specification Errors
According to National Lock Supply, several specification errors frequently occur:
- Under-specifying hardware grades for high-traffic doors
- Installing non-UL-listed hardware on fire-rated openings
- Failing to verify ADA opening force after installation
- Exit device and trim compatibility mismatches
These issues often result in increased maintenance costs and retrofits. Proper specification, installation, and sourcing from ANSI/BHMA-rated manufacturers can help reduce long-term operational challenges.
