Copper Tin Lug for 4 ga Wire

This Westward 23YZ72 lug is a crimpable side terminal made from copper with a tin finish. It accepts 4 ga conductors and provides a straight connection profile for automotive electrical work. The pack contains 25 pieces for fleet or shop use.

Upgrades from basic unplated terminals

The tin coating resists corrosion better than bare copper lugs in harsh under-hood environments. The jump is worth it when connections face moisture, road salt or vibration that degrade unprotected terminals over time.

Suits installers needing cUL listed crimp

The 3/8 in stud size fits common automotive bus bars and battery posts. Buyers who need raised pads, angled shapes or a different gauge size should look at something else.
