To open the handles there are manual quick release levers. Proper use of this mechanism can help prevent spills by keeping the cam arms from opening under adverse conditions, such as high vibrations, pulsing, wear, and hazardous materials. STA LOK II couplers meet the Coast Guard ASTM 1122 87 specifications for Quick Disconnect
