Buying Guide: Key Considerations For Commercial Door Knobs
When selecting commercial door knobs, consider the following factors to ensure you meet security requirements, accessibility standards, and installation practicality:
- Grade And Certification: Prioritize ANSI/BHMA Grade 2 for frequent use, and verify UL ratings for fire resistance where required.
- Backset Compatibility: Most U.S. doors use 2-3/8″ or 2-3/4″ backsets; choose models offering both options to maximize fit across openings.
- Hardware Type: Levers are generally easier to operate in ADA-compliant spaces, while knobs may be preferred for traditional aesthetics or specific doors.
- Handedness And Reversibility: Non-handed designs simplify installation for mixed door orientations; ensure the model is adaptable to left- or right-swing doors.
- Locking Function: Decide between keyed entry, passage, or privacy options based on door location and access control needs.
- Material And Finish: Durable finishes (stainless steel, brushed chrome) resist corrosion and daily wear in high-traffic areas.
- Fire-Rating And Door Compatibility: For corridors and exit routes, verify fire-rating compatibility with fire doors and frame assemblies.
- Maintenance And Durability: Look for models designed to withstand hundreds of thousands of cycles; consider lever mechanics and latch design for longevity.
- Warranty And Support: Check manufacturer warranties and availability of replacement parts for ongoing maintenance.
- Code Compliance: Ensure products meet local building and safety codes for commercial installations.
