Like trailer hitches and ball mounts, electrical connectors range all over the board in shape, size and capability, but no matter what your trailer's electrical functions are, you need a solid connection to keep the power flowing and ensure safety on the road. CURT electrical connectors are designed and manufactured to give you a reliable connection every time you plug in your trailer. Protect your vehicle-to-trailer wiring connection with a CURT electrical socket cover. This 5-way flat dust cover is made with durable plastic to easily resist the elements and help maintain good connectivity. It comes with a convenient attachment tab to avoid loss and is specifically designed to fit a 5-way flat socket on the vehicle side of the connection.
