CPI recommends supporting cable runway runs every 5 feet.
To calculate deflection for loads lighter than maximum loads listed in table, .multiply load
for which deflection is desired by K factor listed in table for cable runway support span utilized.
Example: To calculate maximum deflection using a safety factor of 1.5 for a length of cable
runway supported every 5' and loaded with 80 pounds per foot:
Defection = (80) (0.005) = 0.40"
NOTE: CPI 10250, 11252, 11275 and 14300 cable runway systems
are listed under UL E138966 and tested to the requirements in the
Standard for Safety for Metal Cable Tray Systems, NEMA VE 1-2017
and ANSI/NFPA 70.
