Reversible, Fail-Secure Door Strike

Available in both asymmetric and symmetric models, the Seco-Larm Enforcer Reversible Electric Door Strike offers an ideal solution for converting a wooden door’s cylindrical lockset into an electronic access control system. It allows the door to be locked/unlocked either manually or through an access control/security system. Built for reliable security, the door strike features 1,000 pounds (453kg) of locking jaw strength.

  • Compatible with any cylindrical-door locking system
  • Reversible faceplate for right- or left-hand doors
  • Fail-secure operation (locks if power is lost)
  • Miniature lock body for easier installation

Available Types: Asymmetric (off-center strike portion) or Symmetric (centered strike portion)

Both models of the Reversible Electric Door Strike have a reversible chrome faceplate to fit either right-hand or left-hand doors. The lock body is miniaturized to facilitate installation, and the case as well as all moving parts are corrosion-resistant for long life. The door strike has been tested to last for at least 500,000 lock/unlock cycles.
