Anti-Thrust Devices

 

For Outward Opening Doors

 

Anti-thrust plate is Locksmith terminology for a flat device that is fitted to the external face of a door, overlapping the edge and covering the gap between the door and frame.

  • It is intended to prevent someone using an implement to tamper with the latch or bolt
  • Because it overlaps the edge of the door, it can only be fitted to a pair of doors or a single door that opens outward
  • For the same reason, if it is fitted to double doors that open inward, it cannot be fitted to the door that opens first
  • Kickstop supplies high security Anti-Thrust Plates and very high security Anti-ThrustGuards and a complete list and description is provided below
