Cable tray elbows are essential fittings that allow directional changes in cable tray systems, available in various materials, angles, and sizes, with prices ranging from $0.65 to $3.17 per unit depending on type and bulk quantity.

Specifications

Cable tray elbows are designed to match the main tray in width, depth, and load capacity. Key specifications include:

• Material: Galvanized steel, stainless steel (304/316), aluminum alloy, and FRP/GRP for corrosion resistance and fire safety .
• Dimensions: Widths typically range from 6" to 36", rail heights from 4" to 7", and bend radii from 12" to 36" .
• Angles: Common angles include 45° and 90° elbows, with horizontal and vertical configurations .
• Load Ratings: Must support the expected cable weight, including uniform, concentrated, and dynamic loads .
• Standards Compliance: NEMA VE 1, IEC 61537, BS EN 61537, UL Classified for fire resistance, and ASTM A123 for galvanizing .

Types

Cable tray elbows are categorized based on tray type and orientation:

• Horizontal Elbows: Change direction along the same plane; available for ladder, perforated, and solid bottom trays .
• Vertical Elbows: Allow elevation changes; inside and outside vertical bends are available .
• Material-Specific Types:
  • Galvanized Steel: Durable, corrosion-resistant, suitable for industrial environments .
  • Stainless Steel (304/316): High corrosion resistance, ideal for harsh or outdoor conditions .
  • Aluminum: Lightweight, suitable for telecom and data centers .
  • FRP/GRP: Flame retardant and UV-stable, used in outdoor or chemical environments .

Prices

Cable tray elbow prices vary by material, size, and quantity:

• Aluminum elbows: $0.65 per unit in bulk (10,000+ units) for ladder-type trays .
• Galvanized steel elbows: $1.08–$1.50 per unit depending on bulk quantity and supplier .
• FRP/GRP elbows: $3.17 per unit for large orders (1,500+ units), .
• Alibaba bulk pricing: Around $1.30 per elbow for galvanized or stainless steel . When selecting elbows, consider total installed cost, including shipping, labor, and long-term maintenance, not just unit price .

Summary

Choosing the right cable tray elbow requires matching material, dimensions, load rating, and compliance standards to your project needs. Horizontal and vertical elbows are available in multiple materials, with bulk pricing offering significant cost savings for large installations. Always verify compatibility with the main tray type and environmental requirements to ensure safety and durability.
