This tarp plug is commonly used on the truck side of the tarp wiring. The power for the tarp system is wired into the receptacle. It has little screws on the terminals to hold the wires onto them. Once it is installed, the outside of the plug has a set screw to hold the insulated wires in place. This helps the wires from road vibrations and debris from pulling the wires out of the terminals. This is a dual poled vertical plug; which means that both poles are up/down from each other.
Used on these trailers: Belly Dump.
