    He said the safe working load (SWL) was 1400  pounds. Based on ultimate 
breaking strength (UBS), the SWL is from 20% to 30%  but it's not specified. 
20% gives you a UBS of 7000 pounds, about right for  1/4" but not 3/16".

HD, just go to McMaster-Carr,  call them and place your order.  You'll have 
it at your door in 48  hours and for less $$$


    Always good advice to someone to buy from  someone who knows what they're 
selling. OTOH I don't think there would be  a problem with using the Home 
Depot stuff. The loads exerted by a 54' tower  are pretty reasonable. 
 
    In any case, observation of the LXC Prime  Directive to "DO what the 
manufacturer says" trumps just about everything  else.
