Sea-Dog Battery Terminal Covers 415110-1, 1/2 Inch Stud, Red/Black Pair, 4-2-1 Gauge Cable

The Sea-Dog 415110-1 Battery Terminal Covers insulate integral marine wing nut battery terminals to protect cables and connections from corrosion and accidental shorting. Molded from injection molded PVC, this red and black pair is color coded so you can identify positive and negative terminals at a glance and avoid polarity misidentification during installation or maintenance. Each cover measures 1/2 inch at the stud opening, with an overall footprint of 1-5/8 inches by 1-11/16 inches by 2-7/8 inches, sized for cable gauges 4, 2, and 1. These covers satisfy USCG and ABYC requirements for the prevention of accidental grounding of battery terminals, making them a straightforward way to bring a battery bank up to code. They are designed to fit most marine batteries as well as automotive batteries fitted with add-on marine terminals, so they work equally well on boats, RVs, and other 12 volt DC applications using standard wing nut terminal posts. Sold as a matched red and black pair, they are packaged for easy replacement or for outfitting a new battery installation. Whether you are winterizing, rewiring a battery box, or simply replacing cracked or missing terminal covers, the 415110-1 offers a durable, corrosion resistant solution built to marine standards.
