Hey bud.. sorry to just getting back to you.
Yep the guys below your post and above this one are correct. There is an aluminum "H" that has pipe insulation on it to protect the top. The "H" is connected to the winch ($50 Harbor Freight) that is in the attic. The "hangers" are bicycle hooks from Home Depot w/ rubber hose on them (placed w/ warm soapy water). I'll try to dig up a few more close ups.. and there's a few thread here on hoists.
I like the setup and one person can do it. I think I may have paid $75 total w/ chain, hoist, s-hooks, bicycle hooks, insulation, recessed lighting fixture for hole in ceiling (for the ). The chain is for the joices to take the constant weight off of the winch and to store it.
Good luck and PM me if I can help.
