Booster cable sets are equipped with heavy-duty color-coded clamps which provide easy attachment on hard to reach side, top post, and remote battery locations. The cables are made of copper clad aluminum with tough PVC insulation, and a color-coded tangle-free dual cable construction. This booster cable set is excellent for power transfer and the prevention of crossed connection with its color-coded components. The professional service battery booster cable set is ideal for trucks and large SUVs.
