Quality & Durability
Size: 2 Gauge Cable, Color: 20 ft Black + 20 ft Red
If you need cable for your power supply and ground. Look no further. This is quality from the copper to the insulation. I wasn't sure about buying wires off amazon but this is my new favorite. Done several trucks and they are holding up just fine.

EXCELLENT FLEXIBLE BATTERY CABLE
Size: 2 Gauge Cable, Color: 10 ft Red
This 2awg gauge cable works perfect, nothing more nothing less. The rubber coating on the wire is made with some kind of clothlike material, will work great to resist engine heat with it's thickness. It's real OFC flexible cable very durable and worth the price!!

Good for welding leads
Size: 2 Gauge Cable, Color: 20 ft Black + 20 ft Red
Needed some welding lead extensions for a Miller maxstar clone typically running under 200 amps output. This cable fit the bill nicely.
