A cable tray including a pair of generally parallel or concentric spaced-apart metal side rails and a plurality of spaced apart rungs secured to and extending between the rails at intervals spaced along the rails. The rails and rungs define a cable fill area therebetween. The spacing of the rungs is set according to a pi spacing factor. The rails can have laterally projecting top flange members that extend outwardly in a direction away from the cable fill area and can have lower flange members that extend inwardly in a direction into the cable fill area. The top flanges have a plurality of spaced apart apertures therethrough.
