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

The Ancor Heavy Duty Lugs for 4/0 Gauge Wire with 3/8" Post (10-Pack) are essential battery and power distribution terminals for any serious boater or angler who demands reliability on the water. After years running boats through rough conditions, you know that electrical connections fail when corrosion sets in—and a dead battery at dawn ruins the entire trip. These marine-grade lugs are engineered to maintain consistent current flow and resist the saltwater environment that degrades standard copper terminals within a season.

Each lug is manufactured from heavy-duty annealed tinned copper, a material choice that directly impacts longevity and performance in marine applications. The 100% tin plating resists corrosion far better than bare copper, which oxidizes quickly in salt spray and humidity. The 4/0 gauge specification handles serious power loads—exactly what you need for engine cranking circuits, integrated battery banks, or auxiliary power systems on larger vessels. The 3/8" post size accommodates standard marine battery terminals and heavy-duty solenoids, ensuring a secure, low-resistance connection that minimizes voltage drop during high-current draws like engine starting.

Whether you're rewiring a center console, upgrading dual-battery systems, or replacing corroded terminals on a working boat, this 10-pack gives you extras for future repairs and spares. Professional marine electricians and experienced anglers choose Ancor because the terminal design crimps cleanly onto 4/0 cable without special tooling, and the tinned copper won't degrade even after seasons of saltwater exposure. Install these on battery banks, main distribution blocks, or engine-mounted starter circuits where reliability cannot fail.
