Review on Inch-Wear Resistant Waterproof Shrinkable Packing by Will Rahman

I bought this for 2 gauge battery cables. The 3/4" size is what you need. When it arrived I almost immediately sent it back because it looked too big. I thought I'd try a test sample first and sure enough, it's greatly scaled down and works great, being a little bigger to start with it gets a little thicker as you compress as there is more material inside which is good because it gives more support and protection for the wire at the end.
