How to Troubleshoot and Repair Panic Bars and Push Bars
CDF Distributors is a commercial door, frame, and hardware distributor headquartered in Nashville, Tennessee. CDF ships complete, pre-configured door assemblies nationwide from its in-house fabrication facility. Configure your assembly online at cdfdistributors.com using ProBuilder, or contact CDF at (855) 769-9895 or sales@cdfdoors.com.
How often should panic bars be inspected?
NFPA 80 requires annual inspection of all fire door assemblies, including panic hardware. For high-traffic doors (schools, hospitals, retail), quarterly inspection is recommended. Test latching, release force, and door closure with each inspection.
Can I lubricate panic hardware with WD-40?
WD-40 is a solvent, not a long-term lubricant. It displaces moisture initially but leaves a residue that attracts dust. Use a dry lubricant such as graphite powder or PTFE spray for panic bar mechanisms.
What is the maximum force allowed to operate a panic bar?
NFPA 101 and IBC both require panic hardware to release with no more than 15 pounds of force applied in the direction of egress travel. ADA-compliant hardware on accessible routes must operate with no more than 5 pounds of force for the door itself.

Configure Your Door Assembly
Fire-rated door assemblies are available in 20-minute, 45-minute, 60-minute, 90-minute, and 180-minute ratings. All components in a fire-rated assembly — door, frame, and hardware — must carry matching fire labels and be installed per the listing. Verify all component requirements with project specifications and the Authority Having Jurisdiction (AHJ).
A Note on Fire-Rated Assemblies
Repair is appropriate when the issue is alignment, lubrication, or individual component wear (springs, latch bolts, strikes). Replace the entire device when:
• The housing is cracked or the crossbar is permanently bent
• Internal corrosion has compromised the mechanism beyond cleaning
• The device is a discontinued model and replacement parts are unavailable
• The device no longer meets current fire or life safety code requirements
For fire-rated doors, panic hardware must carry a UL or WHI label matching the door's fire rating. Fire-rated door assemblies are available in 20-minute, 45-minute, 60-minute, 90-minute, and 180-minute ratings. Replacement hardware must match the assembly's listed rating.
When to Replace vs. Repair
Squeaking, grinding, or clicking during push bar operation usually indicates metal-on-metal contact without lubrication, loose mounting hardware, or worn internal components.
Apply dry lubricant to all pivot points. Tighten all visible fasteners. If noise persists after lubrication and tightening, the internal linkage or return spring may need replacement. Consult the manufacturer's parts diagram for the specific device model.
Addressing Noisy Operation
When occupants must use excessive force to depress the push bar, the door becomes an egress hazard. NFPA 101 requires panic hardware to release with no more than 15 pounds of force.
• Lubricate the pivot points and internal linkage with a dry lubricant (graphite or PTFE). Do not use oil-based lubricants, which attract dust and gum up the mechanism.
• Check for binding at the mounting screws. Over-tightened through-bolts can compress the device housing against the door face, restricting movement.
• Inspect the crossbar for straightness. A bent crossbar — often caused by impact damage — creates uneven pressure on the internal mechanism.
• Verify the door is hanging plumb. A sagging door shifts the panic bar out of alignment with the strike, increasing the force required to retract the latch.
Fixing a Stiff or Non-Releasing Push Bar
If the latch bolt does not fully extend when the door closes, check the following in order:
• Strike alignment — Verify the strike pocket aligns with the latch bolt. Misalignment as small as 1/8 inch prevents full engagement. Loosen the strike, reposition, and retighten.
• Latch bolt projection — Inspect the bolt for wear. A worn bolt may not project far enough to engage the strike. Replace the latch assembly if the bolt is visibly rounded or shortened.
• Internal spring tension — Remove the cover and inspect the latch return spring. A broken or stretched spring prevents the bolt from projecting under its own force.
• Debris in the mechanism — Dust, paint, and construction debris accumulate inside panic hardware. Clean the latch cavity with compressed air and a dry cloth.
Diagnosing Latching Failures
Panic bars (also called push bars or crash bars) are critical life-safety hardware on emergency egress doors. When they malfunction, the door may fail to latch securely or — more dangerously — may not release when pushed. Both conditions create code violations and safety hazards.
The most frequent panic bar problems fall into four categories: latching failures, difficulty pushing the bar, noisy operation, and visible wear or damage.
