Cable tray accessory number

Cable tray accessories are identified by specific part or catalog numbers corresponding to their type, size, and function, such as couplers, tees, crosses, brackets, and hangers.

Overview of Cable Tray Accessories

Cable tray accessories are fittings, add-ons, and supporting components used to complete a cable tray system. They ensure proper cable support, facilitate directional changes, and maintain structural integrity and safety. Common accessories include:

• Couplers and Splice Kits: Used to join two sections of cable tray. Example: CE40 and EZBN14EZ for a complete splice (Rexel USA)
• Tees and Crosses: Allow branching of cable trays in multiple directions
• Brackets and Supports: Wall-mounted or ceiling-mounted supports to hold trays in place
• Hangers: Trapeze or center support hangers for overhead runs
• Covers: Solid or ventilated covers to protect cables from dust, water, or falling objects
• Clamps, Nuts, and Bolts: Plastic or metal fasteners to secure cables and fittings

Types of Cable Tray Systems and Corresponding Accessories

• Solid-Bottom Trays: Provide maximum cable protection; require cutting or drilling for cable entry/exit
• Ventilated Trays: Have openings for airflow; may need additional slots for smaller cables
• Ladder Trays: Support cables on traverse bars; often require solid covers for protection

Accessory Numbering and Selection

Each accessory is assigned a catalog or part number by the manufacturer, which specifies its type, size, material, and finish. For example:

• Rexel USA: CE40 and EZBN14EZ (0445225) for splice kits
• RS Components: Accessories from brands like Legrand, Cablofil, and Schneider Electric have unique part numbers for couplers, brackets, and hangers
• ABB T&B Cabletray: Offers CAD and BIM files with part numbers for fittings, covers, and accessories for easy specification in engineering projects When selecting an accessory, consider:

1. Tray type and size (solid, ventilated, ladder)
2. Load capacity (light, medium, heavy-duty)
3. Installation location (wall, ceiling, floor)
4. Environmental conditions (indoor, outdoor, corrosive)

Summary

Cable tray accessory numbers are manufacturer-specific identifiers used to order and specify the correct fittings, supports, and add-ons for a cable tray system. They ensure compatibility with the tray type, load requirements, and installation environment, and are essential for proper cable management and safety compliance in commercial and industrial installations .
