Abstract
A locking mechanism for an actuator prevents the unauthorized operation of the actuator and also permits a viewer to determine whether the actuator is in a locked open, locked closed or unlocked position. The invention utilizes a clear cover guard which is positioned and locked on an actuator body which is attached to a housing. The actuator body comprises threaded bores which permit a bolt to be inserted into the actuator body until it contacts an integral locking cam and driver arm rotatably disposed within the actuator body. The bolt contacts the locking cam in order to selectively lock the integral locking cam and driver arm in a desired position.
