These FTZ heavy duty cable lugs, also known as power lugs, are the absolute best we could find. They are made by a leading manufacturer of electrical components for transportation and industrial applications - connectors are their whole business. They weigh 50% to 100% more than either the FTZ starter lugs or the Ancor Marine lugs, depending on size, and we sell them for about the same price as you'll find standard-duty Ancor brand lugs.

FTZ Power Lugs are made of 99.9% copper, with a substantial tin plating. Unlike many lugs, the pad is a seamless piece for strength, conductivity, and corrosion resistance. The cable size is stamped on each lug.

If you have cables that will not be subject to heavy strain, the standard duty Starter Lug versions are available. They are premium versions of the most common lug specification.

We recommend the FTZ crimping tool, which provides a substantial diamond-shaped crimp with no voids, or an appropriate hydraulic or electric crimper.
