Terminal Lugs & Wire Connectors

If you’ve decided to take on a marine wiring project to install a new bilge pump, wire up a new chart plotter, replace your battery cables or install a marine receptacle in your cockpit to power up an electric deep drop rig, then look to Captain’s Marine Supply. We stock a wide assortment of solder less butt connectors, ring & spade terminals & battery lugs / covers manufactured by Ancor & Sea Dog. You want to ensure that the harsh outdoor elements do not compromise your electrical connections! Please do not use wire cap nuts from your local hardware store to splice wires together on your boat! They are not designed for the harsh marine environment be it fresh or saltwater. So, shop with us today & save on these two great brands! Remember to “Be Prepared on the Water”.
