(100% Copper) Spiral Copper Cap stone, perfect addition to the apex of your pyramid. This cap stone acts like a spring so it holds the tubes in place. Made from 4 gage and 6 gage copper wire. Holes need to be drilled into the top tubes. Half inch from the top of the tube, 9/32 inch drill is what we use. The top spiral has a length to match the Fibonacci sequence and the bottom coil has a length that matches Pi.

Smaller than i thought it was. It's beautifully made. I will have to figure out a way to use it. It's going in my garden for sure. Right now, I have it on my table and my seeds are under it.
