Cablofil wire mesh tray and sup-ports are designed to support any cable load allowed by the NEC when supports are spaced on 8'' spans. Only the hea-viest cables (750 kcmil mulitconductor power or
9.3 Tray Rigidity: For pipe racks, building steel, or tee-structure mountings for which support spacing is determined by others, tray rigidity shall be selected from the manufacturer''s data based on the
The length between support positions will change depending on the cable design, size, materials and weight. For example, an MDPE sheathed cable will be stiffer and therefore require a greater distance
A key factor for the load capacity of the cable trays is (in addition to the support spacing and slant height) the material thickness, which varies ac-cording to type.
