Securing a door with an astragal is a practical and effective way to improve building security and deter break-ins. An astragal is a metal strip—usually steel or aluminum—that runs along the edge of a door or between a pair of doors, covering the gap where locking mechanisms are often targeted. Without an astragal, intruders can exploit this space using simple tools like crowbars or screwdrivers to pry open the door. By reinforcing this vulnerable area, the astragal makes forced entry much more difficult, acting as a physical barrier that enhances the overall strength and integrity of the door.

One of the most critical places to install an astragal is on parkade doors. These doors are often targeted because they provide access to parking areas with vehicles, storage lockers, and sometimes even direct building access. Parkades typically have lower foot traffic and are less frequently monitored, making them an appealing target for intruders. Installing an astragal on parkade doors closes off the latch-side gap and limits the potential for prying attacks. This not only helps deter break-ins but also gives residents or tenants greater peace of mind about their safety and the protection of their property.
Similarly, fire exit doors, while primarily designed for emergency use, are also vulnerable points of entry when left unsecured. These doors often lead to less visible or isolated areas, which makes them attractive to criminals looking to gain quiet entry into a building. Adding an astragal to these doors provides an extra layer of defense without compromising the door’s function as a safety exit. In combination with panic hardware and secure locking systems, astragals make it significantly harder for unauthorized individuals to gain access, all while maintaining compliance with fire codes and building regulations.
Incorporating astragals into a broader security strategy is a cost-effective way to enhance physical security without requiring major structural changes. Whether for commercial buildings, multi-unit residential complexes, or industrial facilities, this small addition can make a substantial difference in preventing break-ins and reducing liability for property managers or owners.
