Re: So where do you run them?
<font color=blue>The confusion for me occurrs with a chain. My hypothesis is that the frictionless pulley is now replaced by a very high friction grab hook from a binder or a clevice or something and in all probability acts as a stress concentrator effectively creating a "weak link" in the chain relatively speaking. Just how much weaker depends on the specific conditions</font color=blue>
Hey Gary, you can add another reason why you prefer straps to chains!
Bottom line, the strength of the chain or strap does not increase. The load capacity of the system does. It is somewhere between 1 and 2 times the single chain or strap. Too many variables to predict what the actual number is.
Should you use 1/2 strength chain or strap because you double it up? NO.
Should you feel that you are getting extra insurance by doubling it up? YES.
