If your storefront business is located in an industrial park or strip mall setting, your front door might be the easiest place for someone to break in.
Here’s why.
In these types of retail settings, the aluminum door frame with a plate of glass in the center is probably the most common door type.
Somewhere in the middle of the frame will be a mortise lock cylinder that when turned with the proper key, operates a swingbolt or hookbolt to lock or unlock the door.
It’s this exterior mortise cylinder that could be a potential weak link.
Left unprotected this mortise cylinder, even if it’s a High Security type, could be twisted off with a common tool many burglars carry with them. Once twisted off, the burglar has access to the locking mechanism, and if he knows how to manipulate the lock mechanism, he can be inside your front door in a matter of seconds.
But there’s a simple solution and it’s very inexpensive.
Cylinder guard rings or armored collars slip around the mortise cylinder lock and are usually made from hardened steel. They are crush proof to wrenches, they are also tapered and free spinning so a wrench can not grab and twist the cylinder so the wrench just slips off.
Armored collars are very easy to install, so to beef up the security at the front door of your business call your local professional locksmith, and ask about having a armored collar ring installed. This simple solution might prevent a thief from walking right in your front door when it’s locked up for the night.
