CA Rung
This is the standard corrugated bottom used for all aluminum, solid-bottom tray systems up to and including NEMA Class 20C. Corrugated bottoms are not available in widths greater than 36". Corrugated bottoms are available with ventilation slots for trough type cable tray designs. For extremely heavy load applications. Ladder type tray is recommended.

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.
