You’re locking up the office late one night when you notice the back exit door feels… off. The push bar sticks, or maybe the latch doesn't quite click into place. It’s a small annoyance in the moment, but in a commercial building, a malfunctioning panic bar is a major safety liability.

When installing fire exit hardware, precision isn't just about aesthetics—it's about saving lives. A panic bar that is installed too high or too low can impede evacuation during an emergency, potentially leading to tragic consequences.

Push bar doors, often called panic bars or crash bars, are critical components of commercial building safety. They ensure a swift exit during emergencies while keeping the building secure from the outside. However, like any mechanical device, door push bars can misalign or loosen over time, leading to security risks or difficulties in opening the door.

Push bar doors, also known as panic bars or crash bars, are essential safety devices designed to provide easy egress during emergencies. However, there are legitimate reasons you might need to lock one temporarily—for after-hours security, during specific events, or for maintenance. Many push bar models from leading push bar manufacturers feature a discreet locking function that requires an Allen key (hex key). This guide will walk you through the process safely and correctly.
