Why does CIT recommend a solid cable tray in ceilings, not “J” hooks or open tray systems?
There are two primary advantages to using solid cable tray over open tray and hook systems: 1) Solid cable tray provides a continuous and level support for the cables. This improves the chances that a Category 6 cable will perform as it was designed to (e.g., for data copper cable, the wiring can support the 1 Gigabit speeds for which it is rated at). 2) Solid tray significantly improves the ability to maintain the cable plant after the initial installation. The tray provides the means to use a “fish tape” or rod to get past congested areas in the ceiling space that are difficult to access reduce the possibility of damaging existing cables.
