Butch D: What is the second 10' dimension for? What is the distance between the vertical sides of the U? If the bottom bar of the U is 1220 mm long, it currently looks like the bottom bar itself could carry a load of 6500 N. However, we do not know how much load this hanger can carry, because we do not know what the vertical sides of the U, and all of the connections, are made of.

Grade A500 2X2X1/4 tubing weighs 5.41 pounds per foot, so 24 feet of it would weigh 129.84 pounds.

The hanging structure is in the shape of a U two 10 foot drops and a four foot piece across the bottom. Attached to the bottom is a connection for a lanyard for fall protection.

Butch D: In post 2, I was assuming you have a static loading. But now we see in post 4, you have a very different application than what I assumed in post 2. For your application, your square tube needs to be able to support a higher load than what is listed in post 2.

Therefore, if never more than one person is attached to your square tube, then it appears you would need to either decrease the length of your current horizontal square tube to 1090 mm long, or if you cannot shorten it, then it appears you would need to increase the horizontal square tube cross section size to, e.g., 57.15 x 57.15 x 6.35 mm.
