** Clear Span of Support: Load—lbs per foot. Published load chart has not been tested with Flexmate. Please consult the factory for load information when using the Flexmate splice option. GS Metals recommends that splice/supports comply with NEMA VE-2 installation requirements.
*** FillRates: Cables used for fill rate testing are 0.1852" in diameter. FLEXTRAY fill capacity is based on NEC allowable fill of 50%. This rule requires that the cable cross-sectional areas together may not exceed 50% of the tray area (width x depth = fill). Fill capacities stated are based on typical Category 5 diameters (0.1852" dia.) in real-world tray installations. Cables will nearly completely fill the cable tray when reaching the 50% cable fill (see illustration below). When the tray is full, the total of the cable area is only 50% of the tray; this is due to empty space between the surface of the cable. TIA recommends 40% fill ratio. FLEXTRAY loads, as shown in the chart, will not be exceeded before fill capacity—see illustration.
