4 AWG Gauge Heavy Wall Lug
4 AWG Heavy wall lugs are extra heavy duty copper cable lugs with tin plating to resist corrosion. The increased wall thickness makes for a solid crimp and each lug is color coded with the crimp die and crimp position(s). With more copper mass in each lug compared to other 4 AWG heavy duty lugs you can expect maximum life and conductivity. The tinned copper will not turn black or green like non-plated copper lugs. These extreme 4 AWG gauge lugs can be crimped or soldered and ideal for battery terminal connections. These lugs are sized to properly fit flexible stranded copper cable and wire gauge sizes such as marine wire (marine battery cable), welding cable and other class k stranded wire types.
