Newmar Power PX-3 Waterproof Junction Box for Marine and Electrical Applications

PX-3 Junction Box

This waterproof junction box is ideal for making wiring connections above or below decks, even in areas subject to occasional spray.

Connector Strips Installed in Boxes

Molded nylon encases pairs of connectors that use screw compression to secure wires without the use of lugs. Ideal for electronic installations. Brass barrels capture wires and are held in place with a stainless steel finger compressed by a screw. The screw does not make contact with the wires, protecting the copper strands from cuts and breakage and meeting ABYC standards.
