These Self-Locking Cam and Goove Couplers offer Increased Safety in applications where no spills are prefered. These Self-Locking Arms will remain locked in the closed positing thereby assuring your line is always attached, until they are manually opened by an operator. To unlock the Self-Locking Handles, the rings at the end of the handle will have to be manually pulled.
WARNING: Only suitable for stationary applications. The release mechanism is released by pulling the release leaver in the same direction as the arm opens, so the coupler arms can be opened if something moves past and the arms catch, or if dragged on the ground and the arms catch onto something.
