Safe Load/Cable Load Only: Allowable uniformly-distributed cable load expressed in lbs/linear foot of tray length, based on the load carrying capability of the rung with a safety factor of 1.5. To convert Safe Load/Cable Load Only to reflect a safety factor of 2.0, multiply the safe loads shown by 0.75.
Safe Load / Cable Load +200 lbs: Allowable uniformly-distributed 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.
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.
