Push bar doors, or crash bars, are commonly found in buildings like schools, hospitals, and offices for their convenient, one-motion opening mechanism. However, it's crucial to know how to secure these doors for privacy and safety. Here's a comprehensive guide on how to lock a push bar door.
Before we dive into the steps, ensure you're familiar with the different types of push bar locks. The two most common are: mortise locks, which are set into the door, and surface-mounted locks, which are attached to the door's face. Our guide will cover both.
Locking a Push Bar Door with a Mortise Lock
A mortise lock system is one of the most secure options for push bar doors. It's integrated into the door, offering excellent security.
To lock a mortise push bar door, follow these steps:
When the Door is Open
1. Lift the push bar to close the door. Most mortise locks engage when the door is fully closed.
2. Once the door is closed, turn the inside knob to engage the lock. This usually requires a quarter or half-turn, depending on the lock's design.
When the Door is Closed and Locked
1. To unlock from the inside, turn the knob. This action releases the latch from the striking plate, allowing the door to open.
2. To unlock from the outside, use a key. Mortise locks often come with a keyed cylinder on the outside for external unlocking.
Locking a Push Bar Door with a Surface-Mounted Lock
Surface-mounted locks are easier to install and are often used in situations where a high level of security isn't required. Here's how to lock these:
When the Door is Open
1. Close the door using the push bar. Most surface-mounted locks engage when the door is closed.
2. Once the door is closed, pull the latch or turn the knob to engage the lock. This action retracts the latch from the striking plate, locking the door.
When the Door is Closed and Locked
1. Unlocking from the inside is just as easy as locking. Simply pull the latch or turn the knob to release the lock and open the door.
2. Unlocking from the outside depends on the type of surface-mounted lock you have. Some may use a keyed cylinder, while others might have a simple thumb turn.
Regular maintenance of your push bar locks is essential to ensure they function optimally and provide the security you need. If you're having trouble with your locks, don't hesitate to call a professional locksmith.
Now that you know how to lock a push bar door, you can enjoy the convenience and safety they offer. So, go ahead, secure your space, and have peace of mind!
