Exit Device Not Latching: Commercial Door Inspection Guide

Define the symptom

Note whether the door closes fully, whether the latch reaches the strike, whether the touch bar remains depressed, and whether the symptom is constant or intermittent. Record traffic, weather, recent construction, and any visible rubbing or obstruction. Photos of the device label and non-sensitive door areas can help an inspector.

• Observation: Door stops short — Useful inspection context: Alignment, obstruction, or closer behavior may need review.
• Observation: Latch misses strike — Useful inspection context: Helps identify a closing or position symptom.
• Observation: Bar stays depressed — Useful inspection context: Distinguishes device behavior from a simple alignment issue.
• Observation: Symptom follows weather/traffic — Useful inspection context: Adds movement and use context.
• Observation: Related openings show symptoms — Useful inspection context: May indicate a broader maintenance concern.

Protect the opening

If an exit opening will not operate normally, follow the facility's safety procedure and notify the responsible manager. Do not wedge, chain, tape, lock shut, drill, or defeat an exit device. Do not make a code-compliance determination from a quick visual check. The NFPA 101 Life Safety Code and the ICC's code-adoption guidance provide life-safety and local-adoption context, but the applicable requirements and qualified review control.

Keep this intent separate from panic-bar triage

“Panic bar” is often used broadly, while exit devices include multiple commercial hardware configurations. This page focuses on documenting an exit-device latching symptom and planning inspection. For broader panic-bar service context, see panic-bar repair. The exact device and opening still need identification before any scope is promised.

Prepare for qualified inspection

Provide the door, frame, device, latch, strike, closer, access-control, and egress context. The responsible professional should use current manufacturer information, such as the installed device's materials in the Von Duprin document library, and the applicable building process. This guide omits adjustment tutorials, wiring, emergency-release, and bypass instructions. For adjacent hardware decisions, see the commercial door and access hardware guide and door closer repair service.

Inspection checklist

• Symptom, frequency, timing, and recent changes are recorded.
• Door and hardware labels are photographed without sensitive access data.
• Responsible manager and facility safety procedure are notified.
• Opening is not wedged, chained, defeated, or adjusted from generic instructions.
• Entry, exit, closing, latching, and related functions are tested after qualified work.
