What’s the Difference Between Panic Bars and Crash Bars?
by John Arkin -
When it comes to emergency exits, the terms "panic bar" and "crash bar" are often used interchangeably—but they don't always mean the exact same thing. Both serve the same general function: allowing people to exit a building quickly and safely during an emergency. But depending on the context, the design, code compliance, or safety features, there may be subtle but important differences between the two.

Understanding Emergency Exit Hardware
Emergency exit devices are designed to allow quick, safe egress from buildings during fires, power outages, and other emergencies. These include panic bars, crash bars, exit alarms, and fire-rated hardware. All of these must comply with safety codes set by NFPA, IBC, and ADA standards.
For commercial properties in Mission Bend, emergency exit hardware is not optional—it’s a legal requirement. Building inspectors often look for clearly marked exits with code-compliant devices. Whether it’s a rim panic device or concealed vertical rods, the main goal is ensuring occupants can get out quickly under pressure.

What Is a Panic Bar?
A panic bar, also called a push bar or exit bar, is a horizontal device mounted on the inside of an outward-opening door. When pushed, it releases the latch mechanism and opens the door instantly. Panic bars are required on many commercial doors by law, especially in spaces with high occupancy.
Panic bars are typically UL-listed and ANSI-certified. They’re designed with public safety in mind, requiring minimal force to operate. In most cases, they’re fire-rated and ADA-compliant as well. Learn more in our article about choosing fire-rated panic bars.
What Is a Crash Bar?
“Crash bar” is a more informal or slang term often used to describe panic bars. In practice, most crash bars are panic bars—but the phrase is more commonly used in casual conversation or by non-industry professionals.
Some use "crash bar" to refer to simpler models without fire ratings or ADA compliance, often found on utility or warehouse doors. These may not always meet code depending on the application. So while the terms may refer to the same type of device, not all "crash bars" are legally acceptable panic bars.
Panic Bar vs. Crash Bar: Key Differences
Functionally, both devices operate similarly—they allow fast, easy egress by pushing a horizontal bar. The difference lies more in context and compliance. Panic bars are a formal, regulated category of exit hardware that meet specific certifications like UL 305 and ANSI A156.3. They are legally required in many commercial and public buildings.
Crash bars may refer to either compliant or non-compliant devices. Some crash bars are not fire-rated or ADA-compliant and may only be suitable for internal storage or warehouse doors. If the door serves as an emergency exit, you’ll need a panic bar, not just any crash-style mechanism.
In short: all panic bars can be called crash bars, but not all crash bars meet panic hardware requirements. To see how this fits into overall door setup, check out our guide on choosing the right door closer.
Code Compliance: When Each Is Required
Any exit door in a commercial building that serves 50 or more occupants must have panic hardware per IBC and NFPA standards. This includes restaurants, retail spaces, schools, and churches. The panic bar must be fire-rated, positively latching, and operable without keys or special knowledge.
Crash bars that lack certifications won’t meet these requirements. They may be allowed on utility or maintenance doors not designated as fire exits. Always check local fire codes before making a purchase or installation decision.
Safety and Security Considerations
Panic bars are engineered to save lives during evacuations. Their spring-loaded latches and non-restrictive push operation reduce risk during high-stress exits. They can be combined with alarms, delayed egress systems, or access control for added security.
Crash bars, depending on build quality, may not offer the same performance or durability. Always prioritize certified panic devices in high-traffic or high-risk areas. If you have a broken latch, read our tips on adjusting panic bars that don’t latch properly.
Installation and Maintenance Tips
Install panic hardware at 34"–48" above the finished floor as per ADA guidelines. Ensure the latch fully engages with a properly aligned strike plate, and that the bar retracts smoothly. If your door is fire-rated, the panic bar must be labeled as such.
Periodic inspections are key—check for worn latches, loose mounting screws, and misalignment. Use a locksmith familiar with panic bar systems to ensure proper setup. We provide installation and maintenance across Mission Bend and nearby cities.
Which One Should You Choose?
Choose a panic bar if your door is an emergency exit, serves the public, or is part of a fire-rated assembly. For back rooms, storage areas, or restricted access zones where code doesn’t mandate panic hardware, a basic crash bar may suffice.
If in doubt, go with the certified panic hardware. It covers all code requirements and ensures safety in the event of an emergency. Need help selecting the right unit? Read our article on where to buy commercial door hardware in Mission Bend.
Common Myths About Panic and Crash Bars
- Myth 1: "Crash bars are cheaper and just as good" – Not if they aren’t certified.
- Myth 2: "Only large buildings need panic hardware" – Any building with 50+ occupancy requires it.
- Myth 3: "You can install any hardware on any fire door" – Not true. It must be UL-listed and compatible.
- Myth 4: "All panic bars have alarms" – Alarms are optional add-ons, not built-in by default.
