To convert Safe Load/Cable Load Only to reflect a safety factor of 2.0, multiply the safe loads shown by 0.75. n2 SAFE LOAD / CABLE LOAD +200 LBS: Allowable uniformlydistributed cable load expressed in lbs/linear foot of tray length, based on the load carrying capability of the rung with a 200 lb. concentrated static load applied at the center of the rung, without collapse. n3 Will not support a 200 lb. concentrated static load applied at the center of the rung. [XX] Two digit code in the safe load limit tables indicates recommended rung option for specified width. * Single rung load capacity: The data shown for 12 " rung spacing is equivalent to the load capacity of the single rung.
