Right angle of cable tray cover
Cable tray covers for right-angle sections are available in flat, flanged, and hat-shaped designs, fabricated from metal or composite materials to fit angled trays and protect cables from environmental hazards.
Types of Covers Suitable for Right-Angle Trays
Flat and Flanged Covers: These are the most common for straight and angled sections. Flat covers can be used without flanges, while flanged covers provide additional support and secure attachment, especially for 3", 4", and 6" wide channels. They are suitable for indoor and outdoor applications and can be fabricated to fit right-angle bends in the tray system . Hat-Shaped (Dome) Covers: Ideal for installations where cables extend above the tray edges, hat-shaped covers can be flat or corrugated and are available in 2" or 4" heights. They can be adapted to angled sections to maintain protection and airflow . Louvered or Ventilated Covers: These covers allow airflow while protecting cables from debris and environmental exposure. They can be supplied in flat, flanged, or hat-shaped designs, making them compatible with right-angle fittings .
Materials and Finishes
- Aluminum and Stainless Steel (304/316): Corrosion-resistant, suitable for harsh environments and outdoor use .
- Galvanized Steel (Mill or Hot-Dip): Economical and durable for industrial applications .
- Composite or PVC: Lightweight, corrosion-resistant, and suitable for specialized applications like telecom tunnels or chemical plants .
Installation Considerations
- Ensure the cover matches the tray width and angle to maintain proper protection.
- Use appropriate clamps and fasteners; some systems include 5–6 fixing clamps for angled sections .
- Verify compliance with standards such as NEMA, NEC, IEC, or UL ratings for safety and environmental protection .
- For outdoor or corrosive environments, select stainless steel or coated finishes to prevent degradation.
Summary
For right-angle cable tray sections, flat flanged, hat-shaped, and ventilated covers are commonly used. They can be fabricated from metal, stainless steel, or composite materials and are designed to protect cables from environmental hazards while fitting the tray geometry. Proper selection ensures compliance with safety standards and durability in both indoor and outdoor installations .
