This is a unique add on lock for your sliding patio door, or sliding windows.  A pressure lock clamps on to the rail of your sliding door or window, preventing the door from opening and triggering an alarm when the lock detects the attempted opening vibration.  It installs in seconds and can be easily moved when you want to bypass the lock and use the door or window.  We've also included a couple of window stickers, warning burglars that your door or window is protected. 

  • 100dB alarm for sliding patio doors or sliding windows
  • 30 second alarm with auto reset
  • Locks door or window in place to prevent opening
  • Heavy duty steel construction
  • Easy installation and easy relocation
  • Battery included and user replaceable
  • Works with nearly every sliding window and door 

Securing your home, apartment or small business has never been easier or more affordable. Simply install the Sliding Window & Door Guard and when the sensor detects vibration, the 100 dB alarm will sound for 30 seconds. The alarm automatically resets for continuous protection. Installation is quick and easy. Battery included and user replaceable.
