Sturdy and works great

Size: 15ft, Style: 8 Gauge

Used this for an approximately 8' run in my electric UTV to power a 2500W inverter running off the 48V batteries so I could power AC tools out in the field. Very thick casing and nice and strong, but flexible enough to route around the frame of the UTV.

Insulation and outside cover materials tough to cut and strip.

Size: 30ft, Style: 10 Gauge

Made in China. Wire works fine but the materials used for insulation and the outer cover are a pain to separate and strip for use. This isn’t like Ancor wire!

Well worth it, Cost efficient and heavy duty! don't hesitate just buy!!

Size: 100ft, Style: 14 Gauge

Very nice and durable wire. well insulated, neatly wrapped and held secure in roll with velcro straps and wire is flexible enough but at the same time sturdy for any job. Wire strippers had no problem pulling insulation coat off. all 100 foot of wire was used on a new pontoon build and will be ordering more from these guys. If you are looking at a couple options of which wire will do you the best look no further and hit BUY NOW!
