Ring Lock Series (RL) couplers have a unique wire ring locking mechanism that locks or disconnects the plug to the coupler with a 1/4" turn. The plugs are made of heat-treated and plated steel and the couplers are made of a combination of plated steel and brass. RL couplers are interchangeable with other industry ring lock couplers.
