I am updating an emergency vehicle and am using this to run the equipment. It’s easy to work with and good thick wire. Came with nice little Velcro straps for keeping the roll together. The finish is nice on the outer casing. Nice gloss black. Excellent product. In fact I bought another 50 foot roll. And the prices for this is extremely good. Glad I found this wiring.
