You can just hang the feeders from the rafters. That's how I have my hanging feeder, but in the coop instead of the run. I drilled a long screw in one of the rafters, sticking out about an inch or two, and hung the feeder on it from a thick piece of wire. Somewhere on here I read a smart tip to grease the wire so that rodents can't climb down to get at the feed. At the rafter end of the wire, I attached it to a piece of chain, and hooked one of the chain's loops through the screw in the rafter. That way I can adjust the height of the feeder easily as my chickens grow (or as the bedding accumulates and gets higher). On the feeder end, the wire ends in a carabiner clip, so I can remove the feeder easily for cleaning.
I would not hang the waterers though. Water is heavy, and it would be an unnecessary strain on your rafters (or whatever you hang it from). Put the waterer up on a couple of bricks or a cinder block instead.
