The material for a given application is chosen based on where it will be used.

For example, different sizes of cable tray used within one run can be connected with reducers.Д¬ommon cable trays are made of galvanized steel, stainless steel, aluminum, or glass-fiber reinforced plastic. Various clamping, supporting and splicing accessories are used with the cable tray to provide a complete functional tray system. Some manufacturers and types provide adjustable elbows, useful for field-fitting a tray around obstacles or around irregular shapes. These can be in various shapes including tees and crosses. Horizontal elbows change direction of a tray in the same plane as the bottom of the tray and are made in 30, 45 and 90 degree forms inside and outside elbows are for changes perpendicular to the tray bottom. To maintain support of cables at changes of elevation or direction of a tray, a large number of specialized cable tray fittings are made compatible with each style and manufacturer. Smaller cables may be laid unsecured in horizontal trays, or secured with cable ties to the bottom of vertically mounted trays. Large power cables laid in the tray may require support blocks to maintain spacing between conductors, to prevent overheating of the wires. Channel cable tray is used for installations with limited numbers of tray cable when conduit is undesirable. These trays may be made of wire mesh, called 'cable basket', or be designed in the form of a single central spine (rail) with ribs to support the cable on either side.Д¬hannel Tray provides an economical support for cable drops and branch cable runs from the backbone cable tray system. Lighter cable trays are more appropriate in situations where a great number of small cables are used, such as for telephone or computer network cables. Tray covers for use outdoors or in dusty locations may have a peaked shape to shed debris including dust, ice or snow. Ladder and ventilated trays may have solid covers to protect cables from falling objects, dust, and water. A ladder tray has the cables supported by a traverse bar, similarly to the rungs of a ladder, at regular intervals on the order of 4 to 12В inches (100 to 300В mm). Small cables may exit the tray through the ventilation openings, which may be either slots or holes punched in the bottom. ДЄ ventilated tray has openings in the bottom of the tray, allowing some air circulation around the cables, water drainage, and allowing some dust to fall through the tray. A deep, solid enclosure for cables is called a cable channel or cable trough. A solid-bottom tray provides the maximum protection to cables, but requires cutting the tray or using fittings to enter or exit cables. Several types of tray are used in different applications.
