Newmar BX-3 Splashproof Aluminum Junction Box

The Newmar BX-3 Junction Box is a cast-aluminum enclosure with grommeted cable entries and included connector strips.

The metal enclosure helps reduce electrical interference around sensitive wiring, which a plastic box cannot do. That makes it the choice near radio or navigation equipment, where a junction box full of connections sits close to antennas and feedlines.

Grommeted cable entries seal around the cable without needing separate glands. Connector strips are included, so the terminations can be made inside the box rather than joining wires and hoping the box protects them.

Cast aluminum suits a wheelhouse, a below-deck space or an engine room. The PX-3 polypropylene box is the alternative where corrosion resistance matters more than shielding, and the two answer different problems. Explore more wire connectors and terminals.
