Features & Benefits

Watertight O-Ring Seal: Comes factory-equipped with a heavy-duty rubber O-ring that compresses tightly into open ports, blocking out pressurized moisture, road salt spray, rain, and fine dust particles.
Corrosion Prevention: Plugs empty entry holes to completely eliminate the core cause of green terminal oxidation, preventing costly electrical short circuits and flickering trailer lights.
High-Impact Composite Material: Molded from heavy-duty, chemical-resistant gray plastic designed to endure aggressive road debris, engine oils, grease, and harsh commercial fleet washing solvents.
Flawless Super 50 Fitment: Engineered as a direct factory-match plug for standard $0.80\text{-inch}$ pre-tapped ports found on Truck-Lite round and rectangular 50 Series enclosures (such as the 50600, 50601, 50800, and 50801).
Tool-Free, Secure Installation: Features a thick threaded compression profile that screws tightly into place, providing quick modifications during harness expansions or routine field maintenance.
