It has become very expensive to ship the 8 foot tall roof towers! If you can buy the 8 foot tower legs locally and drill the holes, I can cut, drill and ship you the shorter parts at a reasonable cost. 6061-T6 aluminum angle can be purchasedthrough  OnlineMetals.  They have warehouse locations in Toledo, OH; Wallingford, CT; Atlanta, GA; Dallas, TX; Los Angeles, CA and Seattle, WA. Speedy Metals has warehouse locations in Milwaukee, WI; Appleton, WI; Rockford, IL; Fraser, MI.  Zoro has 6061 aluminum angles and orders over $50 ship free!

If you have the ability and equipment to cut and drill aluminum, I highly recommend that you consider downloading the DIY instructions for the IO-810 roof tower here. PDF or 7-Zip
