Door hardware is often specified after the door style is chosen, but hardware failures cause most field complaints. On fire-rated doors, hardware is not an accessory; it is part of the tested assembly. This guide explains what to specify for commercial doors.
Core hardware components
| Component | Function | Common requirement |
|---|---|---|
| Hinges | Support the door weight and movement | Heavy-duty or fire-rated hinges on rated doors |
| Locksets | Secure the opening | Grade 1 for commercial use |
| Door closers | Return the door to the closed position | Required on most fire-rated openings |
| Exit devices | Allow safe egress | Panic or fire exit hardware on egress routes |
| Intumescent seals | Expand in a fire to block smoke and flames | Part of the rated assembly |
Specification checklist
- Confirm the door function: interior, exterior, egress, or fire-rated
- Calculate door weight to select hinges with the correct load class
- Check accessibility requirements for lever handles, opening force, and clear width
- Confirm the fire rating and whether hardware is included in the test report
- Choose finish and security level to match the building
- Order spare parts and installation templates with the hardware
FAQ
Can I change the door closer on a fire-rated door?
Only if the replacement closer is listed for the same door assembly or is included in the manufacturer’s certification. Randomly changing hardware can void the fire rating.
What grade of lock is best for commercial doors?
ANSI/BHMA Grade 1 hardware is designed for heavy commercial use. Grade 2 can work for lighter traffic, but Grade 1 is the common specification for entrances and high-traffic openings.
Do automatic operators belong on fire-rated doors?
Yes, when the operator and hold-open device are part of an approved system that releases the door on fire alarm. Confirm the automatic release and fail-safe requirements with the manufacturer.
