what is the overall length of this product?
Unfortunately the manufacturer does not specify.
Does this holder connect to the Super clam as well?
A super clamp has a 1/4 - 20 thread that can be used to attach the holder to it. I actually screwed the holder to a 2 x 6....
what kind of pipe/pole did you use with this? I'm hoping metal gas pipe would work?
I used the Autopole system with exstension rods. You'll also have to purchase 4 c-clamps with additional screws & washers for mounting it to pipe, unless you are bracketing it directly into a supported wall.
