Copper lugs are for large gauge applications for or grounding. Each copper lug is versatile enough that it can be either crimped or soldered to wire. Copper lugs feature a burr-free appearance for an aesthetically pleasing finish and . Features - Color: Silver. - Size: 17.80X10.00X2.30cm/7.00X3.93X0.90in. - Material: . - copper meterial has good electrical conductivity. - Heavy duty construction improves high temperature durability. - AWG wire size and stud size identification on the lug for easy to identify. - Marine grade battery cable ends are made from annealed tinned copper, providing a high degree of conductivity for maximum flow. - These ring terminals have a close end pad design, keeping electrical components, batteries and cables safe and free from moisture, and also prevents solder from leaking during installation.
