Style 2 - Style 2 couplings shall incorporate a positive locking mechanism to lock the cam arms in the closed position when the coupling halves are assembled.
14、 The locking mechanism shall be manually released (the release doesnt have to stay in the released position) before the cam arms can be moved to the open position.
