ECN Forum Forums Code Related Discussion NEC & other Code issues Cable Chase Code Requirement

Spec on the Rack-A-Tiers Cable Chase - Wire Bracket says "Maximum distance between each CC under floor joists is 16″ (when using under floor joists, the maximum distance, on one side from any wall, joist, pipe or ductwork is 12″)". For the application in the attached image, does this mean that the bracket must be within 12" of the center beam? Thanks!
