Fiberglass Cable Tray & Channel
Installation Procedures
Trapeze Hanging Systems The fiberglass trapeze hanging system pictured below may be used to support tray in areas where tray cannot be placed on I-Beams or other existing structures. Trapeze hangers are assembled in the field using components from this catalog. Care should be taken to configure the hanger as shown. When properly assembled, the hanger, pictured below, can support 1000 lbs. with a safety factor of 4 (assuming a balanced load). For NEMA Class C Tray rated at 100 lbs./ft.,we recommend a minimum of one hanger for every 10' of tray (1000 lbs. divided by 100 lbs./ft. = 10'). As with the fiberglass wall bracket, HD-4 clamps and associated hardware may be used with these Trapeze Systems. When trapeze hangers are suspended from I-Beams using polyurethane beam clamps, it is imperative that the fiberglass all-thread rod be screwed completely into the clamp until it bottoms out. Achieving full pull out strength requires total thread engagement. Care should be taken not to over torque the rod.

Fiberglass Cover Installation Procedure Nylon Drive Rivets (Part #NDR1) are the most economical method to fasten cable tray covers, but they require 1⁄4 " field drilled holes on 24" centers along both siderails.

If cover removal or high winds are a concern, either the CC1 or CCE cover clamp may be desired. The CC1 clamp is designed for use on "Z" Style siderail tray and fittings. This PVC coated steel cover clamp requires no field drilling and is easily removed to allow ready access to the inside tray and cables. Six CC1 clamps are recommended for each ten foot length of cable tray cover. The CCE clamp is designed for use with flat cover on Low Profile and "E" Style siderail trays and fittings. The CCE clamp is constructed entirely of fiberglass components and is available in either polyester or vinyl ester resin. Two CCE clamps are recommended for each ten foot length of cable tray cover.
