Ancor 90° Tinned Copper Lug #4/0 - 3/8" - 2-Piece

The Ancor 90° Tinned Copper Lug #4/0 - 3/8" - 2-Piece connector is a marine-grade electrical component engineered for secure battery and power distribution connections in demanding saltwater and high-vibration environments. This two-piece set provides reliable termination for #4/0 gauge wire, a heavy-duty conductor commonly used in large marine systems, RVs, industrial equipment, and off-grid power installations. The 90-degree bend design eliminates costly adapter fittings and simplifies wire routing in tight engine compartments and equipment bays.

Constructed from tinned copper, this lug resists corrosion far better than bare copper—a critical advantage in marine applications where salt spray and moisture accelerate oxidation. The tinning process creates a protective layer that maintains electrical conductivity and prevents white oxidation buildup that degrades connections over time. The 3/8" stud hole accommodates M10 battery posts and standard marine terminal studs, ensuring compatibility with most battery banks and distribution blocks. Ancor's manufacturing standards guarantee consistent crimping geometry and low contact resistance, delivering the voltage drop performance critical to engine starting systems and sensitive electronics.

Marine electricians, RV builders, and off-grid installers rely on Ancor lugs for permanent, code-compliant terminations that survive decades of saltwater exposure. The two-piece quantity is ideal for battery positive/negative pairs or a single installation with a spare for future system upgrades. Proper crimping with a hydraulic or hand-crimper rated for #4/0 cable is required; ensure the lug is fully seated before applying load to achieve rated amperage capacity. This component meets ABYC (American Boat and Yacht Council) standards, making it the specified choice for marine surveyed systems and insurance-approved installations.
