> 3 dayUsed for wiring a heavy duty trailer and this wire with its outer jacket is amazing. Doubt the jacket will wear through like the original wiring did. Jacket is nice and thick, wires are tightly wound. Fit through the channel in the trailer for all the wiring, which consists of 15 lights, and 4 brakes, along with a 7 wire harness.

Greater than one weekThis wire is as advertised, with a very thick outer insulation that protects the inner insulated wires. Color coded black and red, the leads are easy to tell apart on each end. It took heavy duty strippers to remove the outer insulation, but I have no qualms about leaving a portion of the run exposed as the cover should withstand UV and most solvent exposure. Not inexpensive, but very good value.
