* CAT5e 4 pair PL approximated at .19 in2 in diameter, CAT 6 4 pair PL cable approximated at .25 in2 in diameter and CAT 6A 4 pair PL approximated at .30 in2
** Allowable fill ratios are based on the NEC rule that the cross sectional area of all the cable installed in the cable tray not exceed 50% of the cross
sectional area of the cable tray (width x depth). TIA suggests a 40% fill ratio.
*** Snake Tray series 201, 401 and 501 are recommended to be supported every four (4) feet. However larger spans can be accommodated.
