Cable tray accessories specifications and models

Cable tray accessories include fittings, covers, supports, and mounting hardware designed to meet international standards and accommodate various cable management needs.

Overview of Cable Tray Accessories

Cable tray systems are modular solutions for routing and supporting electrical and data cables. Accessories are essential for installation, structural support, and cable protection, and they include:

• Fittings: Elbows, tees, crosses, reducers, and offsets to change direction or width of the tray.
• Covers and Lids: Solid or ventilated covers to protect cables from dust, debris, or mechanical damage.
• Supports and Hangers: Brackets, clamps, and suspension systems for mounting trays to walls, ceilings, or equipment racks.
• Splice Plates and Connectors: For joining straight sections or securing tray segments.
• Cable Management Accessories: Dividers, clamps, and grounding kits to organize and secure cables within the tray.

Materials and Finishes

Cable tray accessories are manufactured from steel, stainless steel, aluminum, or pre-galvanized steel, with finishes such as hot-dip galvanization, powder coating, or anodization to enhance durability and corrosion resistance . Material selection depends on environmental conditions, load requirements, and compliance standards. Typical sheet thicknesses range from 1.0 mm to 2.0 mm .

Standards and Compliance

Accessories are designed to comply with international standards including:

• BS EN 61537:2023 – Cable tray systems and accessories
• NEMA VE 1-2017 – Metal cable tray systems
• CENELEC EN 50173-1, EIA/ITA 568 A, ISO/IEC 11801-1:2017 – Cabling standards
• UL Certification – Ensures safety and performance for electrical installations
