The E1 from Fortress Interlocks is an extracted key adaptor the company has added to its amGard range of modular safety gate switch interlocks. The new product ensures the door to hazardous machinery cannot be opened without removing the safety key, and the machinery cannot be restarted until the key is returned.

By being designed to trap an actuator in the head until the key is removed, the mechanism allows the “gate” to wing 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. E1 ensures a specific sequence of operation and can be stacked or combined with other access and safety key adaptors. Up to five key adaptors can be used in one configuration. Suitable for either hinged or sliding door applications, E1 also works with Fortress amGard LOK or STOP bodies.
