Just some random info. This is based on physics, not specific types of webbing or rope. We used to use these charts at work, and I haven't really seen them up yet. http://www.iandisling.com/pdf/tags/s...structions.pdf

This company gave me a coffee mug once, wish I still had it. We ordered thousands of dollars of slings, and to differentiate ours from other contractors on the site, I asked a guy to paint the CHOKERS. (meaning steel, wire rope) He painted the nylon slings as well, and we could no longer use them. oops.
