Having to be very portable this is what I use for bags. Made of 2-10 ft. 1/2” conduit 2 -5/16 x 3” bolts 8 flat warshers 2- 3” s hooks. Toltal width is approx. 32” & center of bend is aprox. 44 1/2”. I did not make these so I don’t know what radius of bend is.
Mine is a little big and not that portable so I built a top out of some scraps I had. The top is easy to take off if I want to move it. The frame is made out of some scrap steel I had. My daughter made the sign for me
