When you need power in tough weather or harsh climates, then the BOSS line of wiring devices is for you. Through heavy rain, snow & ice, or howling dust storms, the BOSS Type 4 water-tite/weather-proof receptacles, plugs, and cord ends stand up to all of the abuse Mother Nature (and roughnecks) can throw at them. Cast aluminum bodies, caps, and rings combined with durable rubber boots and gaskets make this line both durable and reliable.
