Dead bolt locks (Series 9014)
Electric strike latch designed especially for dead bolts: As opposed to standard electric strikes, when the door is open the electric strike latch is hinged open and therefore in the position to accept the bolt.
When the door is closed, the electric strike latch is moved into the closed position by the bolt. This is a reliable method for preventing the door from being locked unintentionally when it is open. Also available as a security electric strike.
