Sea-Dog Wing Nut Style Battery Terminal Set, Positive and Negative, Die Cast Lead

The Sea-Dog Wing Nut Style Battery Terminal Set (415210-1) converts standard battery posts to stud connectors, letting you disconnect a marine battery quickly without tools. The set includes one positive and one negative terminal, each cast from die cast lead for corrosion resistance and reliable conductivity in a marine electrical environment. Each terminal is polarity specific to meet USCG regulations, so the positive and negative terminals are sized differently and cannot be mixed up during installation. The wing nut design allows the connection to be tightened by hand and released quickly in an emergency or for battery maintenance, without needing a wrench. This set is sold as a display packed pair (one positive, one negative) and is intended as a direct upgrade or replacement for standard battery post clamps on boats and other marine applications where quick-disconnect capability is desired.
