Seamless, tin-plated copper lug for 4 AWG stranded copper cable on a 1/4" stud. The closed seamless barrel crimps evenly on fine-strand battery and welding cable, and the tin plating resists green corrosion. UL and cULus Listed. Made in USA.

Use it for: battery, starter, inverter, solar, winch and ground cables in vehicles, boats, RVs and backup-power systems. Crimp with a hex crimper or solder with a solder slug.

Getting the right size: match the barrel to 4 AWG and the hole to the 1/4" stud — other combinations are in our tinned copper lugs. Finish the joint with adhesive-lined heat shrink and matching red or black battery cable.
