Long Haul Components

Few pieces of equipment see more abuse from the weather, the road, and the job than your trailer. If it’s not hauling heavy loads in the rain, it’s baking in the sun on a shadeless job site. And whether your trailer gives you years of solid use or gives up when the going gets tough has a lot to do with the quality of your trailer wiring. So if you’ve got a boat or a work trailer, a 6’ or a 14’ trailer, or 4 or 7way trailer wiring you can count on our replacement harnesses, junction boxes, and wire testers to keep you on the road and running strong.
