I just bought a different work truck. It belonged to a company that installs sprinkler systems. Attached to the rack is a PVC tube. Inside the tube is a bunch of all thread. 8' or 10' lengths,I haven't bothered to pull any out and measure. Its the size they use to hang the water pipes with, so its pretty stout. Anyone want or need it, just come get it. There is probably 40 or 50 feet of it.
