Truck-Lite 50600 Super 50 Junction Box Kit – 12-Port, 16-Terminal, Grey/Clear Plastic Surface Mount

Massive Port Capacity: Equipped with 12 pre-tapped ports and 16 terminal connections to comfortably handle heavy-duty trailer wiring systems and multiple harness expansions.

Smart "Dogbone" Grounding: Features a dual-ended dogbone ground strap that allows 4 terminals to act as a common ground, cutting down on extra hardware and installation costs.

Transparent Diagnostics: Constructed with a crystal-clear polycarbonate lid so you can inspect internal wiring, terminal connections, and blown circuits at a glance without breaking the environmental seal.

Weatherproof & Chemical Resistant: Built from a rugged, high-impact grey ABS/polycarbonate plastic blend with an integrated silicone gasket. It seals tightly against moisture, road grime, salt, and corrosives to minimize electrical failures.

Roomier Interior Layout: An enlarged interior housing footprint leaves plenty of space to comfortably organize, crimp, and manipulate thick gauge wires and terminal block connections.

Heavy-Duty Mount: Designed with 4 eyelet-reinforced mounting holes embedded into the base for superior vibration resistance and secure surface mounting.
