Newmar Junction Boxes & Marine Wire Accessories

Fisheries Supply carries marine junction boxes and accessories for all your wiring needs. Our Newmar junction boxes are made from high-impact polypropylene, providing a watertight seal for making wiring connections above or below decks. Whether you need a completely waterproof marine electrical box for your wheelhouse, engine room, or below decks or a splashproof marine outlet box for areas subject to occasional spray, we have the right solution. Our EX series of submersible junction boxes and BX series of splashproof marine electrical boxes, as well as our DX and CCX series of waterproof thru-dex fittings, are both rugged and non-corrosive. In addition to marine watertight junction boxes, we also offer quality bus bars, terminal strips, and connector strips to help you complete your wiring job efficiently. When choosing a junction box, you can consider things like the voltage and amperage rating, as well as the UL 94 flame rating, rigidity, and heat resistance.
