Sliding-Glass Patio Door Security

sliding glass door fresno locksmiths adviseSliding glass doors are secured by latches not locks. They are vulnerable to being forced open from the outside because of these inherently defective latch mechanisms. This can be easily be prevented by inserting a wooden dowel or stick into the track thus preventing or limiting movement. Other blocking devices available are metal fold-down blocking devices called “charley bars” and various track-blockers that can be screwed down.

The blocking devices described above solves half the equation. Older sliding glass doors can be lifted up and off their track and thereby defeat the latch mechanism. To prevent lifting, you need to keep the door rollers in good condition and properly adjusted. You can also install anti-lift devices such as a pin that extends through both the sliding and fixed portion of the door. There are also numerous locking and blocking devices available that will prevent a sliding door from being lifted or forced horizontally.

  • Use a secondary blocking device on all sliding glass doors
  • Keep the latch mechanism in good condition and properly adjusted
  • Keep sliding door rollers in good condition and properly adjusted
  • Use anti-lift devices such as through-the-door pins or upper track screws
