The Newmar BX-1 Junction Box is a compact cast-aluminum enclosure with two grommeted entries and an installed compression connector strip.
Two cable entries makes this the small box in the range, for a single junction rather than a distribution point. The BX-3 handles multiple entries where several circuits meet, and matching the box to the number of cables avoids either a cramped enclosure or a mostly empty one.
The metal enclosure helps reduce electrical interference around sensitive wiring. That is the reason to choose aluminum over plastic near radio or navigation equipment, where a junction sits close to antennas and feedlines.
Compression fittings on the installed connector strip secure wires without separate lugs. It suits low-current wiring in a wheelhouse, a below-deck space or an engine room. Explore more wire connectors and terminals.
