This East Penn duplex wire runs two 12-gauge, 100% copper conductors side by side inside a single gray PVC jacket, which is the gauge commonly recommended for electric trailer brake wiring. The jacket keeps the pair together as one oblong cable and shields the conductors from weather and abrasion during routing.
It's sold as a 100 ft spool, enough for most single-trailer brake wiring runs with material left over.
