The Alliance MRO 900-LC-40 LC40 welding cable connector set provides a detachable male and female connection for 1/0 through 2/0 AWG welding cable. The cam-action, ball-point design locks with a twist and pulls the connector halves securely together for efficient current transfer. Precision-machined heavy brass components resist rust and corrosion, while molded heat-resistant rubber covers withstand cold, abrasion, ozone, oils and solvents. Tapered cover ends help keep moisture, oil and dirt away from the connection. The set includes one male connector, one female connector, two heat-resistant rubber covers, two brass connection sleeves and a wrench. The connectors are interchangeable with popular like-size competitor models.
