Anti-Thrust Devices

 

Anti-thrust plate is Locksmith terminology for a flat plate that is fitted to the external face of a door, overlapping the edge and covering the gap between the door and frame to prevent someone using an implement to tamper with the latch or bolt.

 

  • All Kickstop Anti-Thrust Plates are made from 3mm thick steel.
  • Because the plate overlaps the edge of the door, it would 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.

 

 

Before ordering

*Very carefully check the type of keyway you require

Traditional UK (UK) - Euro profile cylinder (EU) - Oval cylinder (OV)

 

NB: Choose the device/plate with the correct shape of keyway
