[QUOTE="Art Welter, post: 117019, member: 52"] Re: Another case of questionable rigging? Simon, Assuming two real purple Spansets in good condition, each choked with equal load, the WLL is 4240 pounds. Spanset uses a 5/1 safety factor, minimum breaking strength should not be less than 21,200 pounds. Some portion of the truss would likely fail before the Spansets. Spansets may not be legal for support in some jurisdictions as polyester can melt and burn, if you see speakers on fire supported by Spansets, stand well clear of the fall zone ;^). Art [/QUOTE]
