Fiberglass Cable Tray & Channel Structural Designs Fiberglass Cable Tray Styles
All fiberglass cable trays have a 1.5 safety factor that meets the NEMA FG 1 safety factor requirement of 1.5 times the allowable working load. Fiberglass cable tray is also available with a solid bottom upon request. Solid bottom tray consists of a standard ladder tray with a flat fiberglass cover material bonded to the bottom of the tray.
Fiberglass cable tray systems are available in flange-out and flange-in styles. Type CZD deep tray is a flange-out design. Type LC Low Profile tray and standard tray types BE and CE are flange-in designs. The "Z" siderail profiles allow for easier cable loading and cover attachment or removal. Fiberglass "Deep Z" profile tray, Type CZD, provides six inches of cable fill depth and is only available in NEMA load class C+. Fiberglass "E" Style siderail profiles are flange- in designs that are especially useful when space is a consideration, such as on closely spaced parallel runs or flush wall mountings. "E" rail profile provides four inches of cable fill depth and is available in NEMA load classes C as BE and C+ as CE. Five inch load depth is available in NEMA load class C+ as FE. The Low Profile cable tray, type LC, is an "E" siderail profile that has a three inch cable loading depth. Type LC cable tray is ideal for control wiring and lighter cable runs that do not require numerous circuits.
