Ancor 90° Tinned Copper Lug #4/0 - 5/16" - 2-Piece

The Ancor 90° Tinned Copper Lug #4/0 - 5/16" - 2-Piece is a marine-grade electrical connector designed for high-amperage applications requiring reliable, corrosion-resistant connections. These lugs are essential in battery banks, power distribution systems, and heavy-duty marine or automotive electrical installations where secure cable termination is non-negotiable. The 90-degree bend geometry makes this connector ideal for tight spaces and complex wire routing scenarios where standard straight lugs cannot fit.

Constructed from tinned copper, this lug offers superior conductivity and exceptional corrosion resistance compared to bare copper alternatives—a critical advantage in saltwater or high-humidity environments. The #4/0 wire gauge accommodates extremely large cables (up to 107 mm² cross-section), making it suitable for heavy-load applications including marine battery systems, RV power distribution, and industrial electrical work. The 5/16" stud hole accepts standard battery terminals and distribution blocks, ensuring compatibility with industry-standard equipment. Tinning the copper prevents oxidation and extends service life, reducing maintenance and ensuring consistent electrical performance over years of use.

Professionals and enthusiasts managing marine electrical systems, RV power systems, and off-grid battery banks rely on these lugs for dependable connections that withstand vibration, thermal cycling, and corrosive environments. The two-piece set provides enough connectors for a complete battery-to-distribution circuit configuration. Installation requires crimping tools rated for #4/0 cable and a clear understanding of proper termination practices; ensure all connections are tight and protected from moisture to maximize longevity and safety.
