About the Ancor 255101: 100-Piece Lug Kit

Nothing derails a battery or inverter install faster than discovering the one lug size you need is the one you don't have. The Ancor 255101 solves that problem in bulk: 100 tinned copper lugs spanning 8 AWG through 2/0 AWG, with both 5/16" and 3/8" stud holes stocked for every gauge. That combination covers the vast majority of terminal studs found on batteries, inverters, busbars, shunts, and disconnects, so whether you're a professional installer or building out your own system, the right lug is always within reach.

Built From 100% Tinned Copper

Ancor Marine Grade lugs are manufactured from heavy-duty annealed tinned copper, which provides maximum current flow through the connection. The full tin plating resists corrosion from salt and moisture, which is exactly why tinned lugs have become the standard for off-grid, mobile, and coastal energy storage installations, not just boats. Bare-copper lugs oxidize over time, and oxidation means resistance, heat, and voltage drop at the worst possible point in your system.

Seamless Barrels Crimp Stronger

Each lug uses a seamless barrel design that delivers maximum strength when crimped, with no seam to split open under crimping pressure. The closed-end barrel also seals out moisture from the cut end of the conductor, keeping the strands underneath dry and corrosion free.

UL 486A Listed for Code-Conscious Installs

These lugs carry the UL 486A listing for wire connectors, giving inspectors and system owners alike confidence that the terminations meet a recognized safety standard. For energy storage systems where every connection is scrutinized, that listing matters.
