I used inch and a half x 1/8" wall square aluminum tube 7' long. I used square tubing because it made it easier to bolt the eye straps and the legs to slide the pivot bolt through on the tabernacle. The legs are made of inch and half x 1/8" aluminum with 3/8th hole drilled for the pivot bolt. If you have a metal supermarket somewhere there you can get the material for $23.
