[SML] Unistrut safety factor specs?

[Phil Haney]

Page 24 and 25 in the catalog list beam and column loading data for P1000

As presented in Jay Glerum's book and class (Stage Rigging Fundamentals), I
thought safety factor was something you multiplied your load by to arrive
at the minimum rating for your hardware.

For example, if you have to lift a 500 lb load and you want a safety factor
of 10, you would use hardware rated at a minimum of 5,000 lbs.

Is that it, or am I missing something? And does this help?
