Why Your Business Needs Cylinder Lock Guards

As a business owner with a storefront, we’re sure you’re constantly bombarded with tips and recommendations for complicated security measures. Friends and fellow business owners may flaunt their new security cameras or other tech, all the while missing out on core security components. One such security component? A cylinder guard.

Exploring the Standard Mortise Cylinder

Before we explain what a cylinder guard is, it’s probably best to explain standard mortise cylinders. Typically, these cylinders are made of soft brass. What does this mean? It means that a burglar can use special pliers, a pipe wrench, or another device to tear the cylinder out of the door, exposing an opening through which they can operate the deadlock.

What is a Cylinder Guard?

Cylinder guards were designed specifically as a solution to this problem for commercial property owners. Cylinder guards are fully beveled outer shield rings to provide an extra layer of protection against prying. The guard makes it virtually impossible to grip even with tools. They are made of hardened steel so that they can’t be damaged by any standard hand tool.

What Cylinder Guards Protect Against

  • Wedging
  • Prying
  • Drilling
  • Cutting

Where Can I Use Cylinder Guards?

Cylinder guards can be use on most leading manufacturers’ locks, whether the cylinder is surface mounted or morticed into the door.

4 Simple Steps for Cylinder Guard Installation

  1. Loosen the set screw for the lock cylinder.
  2. Unscrew the lock cylinder. It should come out of the mortise cassette.
  3. Put the cylinder guard on it, making sure the lock cylinder is recessed.
  4. Screw the lock cylinder back in place, making sure the threads line up.

Tips to Note about Cylinder Guards

  • If done correctly, you can tighten the set screw and test the mortise cylinder.
  • If the cylinder guard causes the lock’s cam to not contact the mortise cassette correctly, it means you need a slightly longer lock cylinder or that you need to screw the lock cylinder in farther.
