a couple notes...

the "black iron pipe" is all 1/2" thick tubing. the pulleys are heavy duty and rated at 420lbs. The cable (called "wire rope" or "aircraft cable") is 3/16" vinyl coated (for smooth pulling) and rated at (I think) about 800lbs. You'll need pro'bly about 15' of cable and 4 clips to secure the loops for the handle and the weight plate T unit.
