Fortress Interlocks E1 extracted key adaptor ensures the door to hazardous machinery cannot be opened without removing the safety key, and cannot be restarted until the key is returned. It traps the actuator in the head unit until the key is removed, which allows the “gate” to swing over the keyhole. While the actuator remains out of the head, the gate remains over the keyhole, preventing the key being returned to the lock. The adaptor can be stacked or combined with other adaptors; up to 5 key adaptors can be used in one configuration. It is suitable for hinged or sliding door applications.
