Ancor Heavy Duty Lugs - 4/0 Gauge Wire - 3/8" Post - 10-Pack

Ancor Heavy Duty Lugs for 4/0 Gauge Wire with 3/8" Post are essential crimped terminals designed for serious marine electrical installations. These lugs are ideal for applications such as running a new battery bank, upgrading alternator connections, or wiring high-amperage charging systems aboard boats. Their robust design ensures secure connections that are critical for safety on the water.

Constructed from copper, these heavy-duty lugs resist oxidation and salt-air corrosion, outperforming tin-plated alternatives. The crimp design ensures a permanent, gas-tight connection that remains secure under vibration and thermal cycling. Proper crimping with a quality marine crimper is essential to achieve a joint with resistance lower than the wire itself, especially when dealing with amperage demands exceeding 200 amps.

These lugs are perfect for anglers and cruisers looking to upgrade their battery systems, install auxiliary chargers, or hardwire trolling motors and thru-hull electronics. The 3/8" post is compatible with standard marine battery terminals, fused distribution blocks, and most aftermarket electrical panels. Always ensure you use a crimper rated for 4/0 cable to maintain optimal performance.
