Ancor 2AWG 3/8" Lug Tinned Copper 25 Pack

The Ancor 2AWG 3/8" Lug Tinned Copper 25 Pack is the marine electrician's choice for reliable, corrosion-resistant electrical connections in saltwater environments. After years running boats in coastal conditions, any serious skipper knows that cheap battery terminals and wire lugs will fail—often at the worst moment. These heavy-duty tinned copper lugs deliver the current capacity and salt-spray durability you need when wiring battery banks, shore power systems, and high-amperage circuits on commercial or recreational vessels.

Manufactured from 100 percent annealed tinned copper and UL 486A certified, these lugs provide maximum current flow while resisting the oxidation and corrosion that plague bare copper in marine service. The 2AWG wire gauge handles substantial amperage—ideal for main battery cables, alternator connections, and thruster circuits—while the 3/8" stud diameter fits standard battery posts and marine electrical terminals. Tinning the entire copper surface prevents white corrosion and green oxide buildup, which degrade conductivity and create dangerous voltage drops under load. The 25-pack format ensures you have spares on hand for maintenance, repairs, or system expansions without breaking bulk.

Boaters upgrading battery systems, adding auxiliary power, or rebuilding aging electrical panels rely on Ancor marine-grade lugs to eliminate corrosion-induced failures. Whether you're crimping connections in a fishing boat's 24V house bank, a trawler's engine start circuit, or a cruising sailboat's solar array, these tinned copper lugs outlast cheaper alternatives by years. Compatible with standard marine crimpers and UL-listed terminals, installation is straightforward—simply match your 2AWG wire gauge, crimp securely, and seal with marine dielectric grease for maximum longevity.
