Mueller Crocodile Clip The BU-21M series was designed to thrive in coastal/marine environments. The solid copper and stainless steel construction provides excellent corrosion resistance while the copper lug enables easy solder connection. It has current rating of 100A. Salt water testing has shown that these clips will last up to five times longer than traditional steel or copper clips. The BU-21MPN has no markings, while the BU-21MPS has a ’+' symbol stamped through it. It acts as a connector. The larger versions of these clips, called automotive clips or battery clamps, are made of solid copper. For low electrical resistance, it is used with thick insulated copper cables to make connections between automobile batteries. Features and Benefits • High strength
