Powder jack pole diameter

[reflextruckliners]

I would like to upgrade to the new sectional poles from Powder Jack. If someone has a current powder jack with a long pole could you measure the diameter for me. I am using a VW car Jack and it uses a 20 mm outside diameter pole. Thanks for your time.

I thought I was the only ones cheap enough to use an old vw Jack. My sectional poles out of pipe are heavy. I would like to try something aluminium. How heavy of gauge tubing/pipe is used?
