Great wire for demanding installs
I used the 14g and 12g duplex wire for wiring on my off-road rig. I live up in the northern U.S. Rockies and off-road a lot in the deserts across the southwest U.S. The arid terrain, UV exposure, and alternating deep cold and heat kept decomposing other wiring I have tried, especially on the roof rack lights and accessories. The quality of this wire is noticeably better than other automotive wiring I have used! Heavy duty outer jacket. The insulation on the inner wire is robust as well. Despite the heavy duty coverings, the wire lays out well. I am questioning the gauge on some of my prior wires as the strands on this Ancor wire seem beefier than the same grade of the auto wire used previously. All in all, a great product.

Perfect!
I’m very happy with this product, and I cannot wait to rewire my entire boat from A-Z with this, and other sizes of wire I have recently purchased. I love the outer coating, for durability when routing this underneath the boat, through the pontoon, and up through the deck. I will also be protecting this wire inside a mesh sleeve, and expect to get a lot of years of use out of it.

This stuff is great
I used this to wire up my camper van. It was great and easy to use. Don't take short cuts and by some cheaper product. This wiring is worth it.

We needed 12/2 AWG cable for wiring some things on our boat. You can't beat the Ancor price you are getting here on Amazon!
