Several types of tray are acclimated in altered applications. A solid-bottom tray provides the best aegis to cables, but requires acid the tray or application accessories to access or avenue cables. A deep, solid asylum for cables is alleged a cable approach or cable trough.1
A aerial tray has openings in the basal of the tray, acceptance some air apportionment about the cables, baptize drainage, and acceptance some dust to abatement through the tray. Baby cables may avenue the tray through the blast openings, which may be either slots or holes punched in the bottom. A ladder tray has the cables accurate by a bisect bar, analogously to the rungs of a ladder, at approved intervals on the adjustment of 4 to 12 inches (100 to 300 mm).
Ladder and aerial trays may accept solid covers to assure cables from falling objects, dust, and water. Tray covers for use outdoors or in arenaceous locations may accept a ailing appearance to afford bits including dust, ice or snow. Lighter cable trays are added adapted in situations area a abundant amount of baby cables are used, such as for blast or computer arrangement cables. These trays may be fabricated of wire mesh, alleged "cable basket",1 or be advised in the anatomy of a individual axial back (rail) with ribs to abutment the cable on either side.
Large ability cables laid in the tray may crave abutment blocks to advance agreement amid conductors, to anticipate overheating of the wires. Smaller cables may be laid apart in accumbent trays, or anchored with cable ties to the basal of vertically-mounted trays.
To advance abutment of cables at changes of acclivity or administration of a tray, a ample amount of specialized cable tray accessories are fabricated accordant with anniversary appearance and manufacturer. Accumbent elbows change administration of a tray in the aforementioned even as the basal of the tray and are fabricated in 30, 45 and 90 amount forms; central and alfresco elbows are for changes erect to the tray bottom. These can be in assorted shapes including tees and crosses. Some manufacturers and types accommodate adjustable elbows, advantageous for field-fitting a tray about obstacles or about aberrant shapes.2
Various clamping, acknowledging and splicing accessories are acclimated with the cable tray to accommodate a complete anatomic tray system. For example, altered sizes of cable tray acclimated aural one run can be affiliated with reducers.
