Push bar doors, commonly found in commercial buildings and emergency exits, present a unique challenge when it comes to securing them from the inside. Unlike traditional doors, they don't have standard locking mechanisms. This guide provides several methods to effectively lock or secure a push bar door from the inside, enhancing safety and security.
Understanding Push Bar Door Mechanisms
Before diving into solutions, it's crucial to understand the mechanics of a push bar door. These doors are designed to open outwards, often for emergency egress. This means any internal locking mechanism needs to override the outward-pushing force. There's no single "best" solution, as the ideal approach depends on the specific door and your security needs.
Methods to Secure a Push Bar Door from the Inside
Here are several effective methods to prevent unauthorized entry through a push bar door from the inside:
1. Using a Simple Door Wedge
This is the simplest and most readily available solution. A door wedge, typically made of rubber or wood, is placed at the bottom of the door, preventing it from opening fully. While not a lock, it adds a significant deterrent.
Pros: Inexpensive, readily available, easy to use. Cons: Not very secure; easily removed; offers minimal protection against determined individuals.
2. Employing a Portable Door Lock
Several portable door locks are designed to fit over a standard door handle or push bar. These often utilize a locking mechanism that secures the door from the inside. Look for options designed for use on commercial doors.
Pros: Relatively inexpensive; portable; offers more security than a door wedge. Cons: May not be suitable for all push bar door types; can be easily bypassed by forcing the door or removing the device.
3. Installing a Rim Lock or Deadbolt
For robust security, consider installing a rim lock or deadbolt designed for push bar doors. A qualified locksmith or handyman can install these, ensuring a secure and reliable solution. These solutions directly address the issue of preventing the door from opening.
Pros: Highly secure; durable; permanent solution. Cons: Requires professional installation; more expensive than other options; may require modifications to the door frame.
4. Utilizing an Internal Latching Mechanism (If Available)
Some push bar doors have a built-in internal latch or locking mechanism. This is usually a small lever or button that can be engaged to secure the door. Check for this option on your door.
Pros: Simple and convenient if the feature is present; no additional hardware required. Cons: Not all push bar doors have this feature; may not offer robust security.
5. Implementing a Security Bar
A security bar fits across the door frame, preventing the door from opening. They often use pressure to hold the bar in place across the door. This adds an extra layer of security against forceful entry.
Pros: Strong deterrent against forced entry. Cons: Not a lock; requires a space between the floor and the door to install.
Choosing the Right Solution
The best method for locking your push bar door from the inside depends on your specific needs and budget. Consider the following factors:
- Level of security required: Do you need a simple deterrent or robust protection against forced entry?
- Budget: Portable locks and door wedges are the most affordable, while installing a rim lock or deadbolt is more expensive.
- DIY skills: A door wedge is easy to use, while other options may require professional installation.
Remember to always prioritize safety and choose a solution that best suits your individual circumstances. When in doubt, consult a qualified locksmith for advice and professional installation.
