Cable tray supports come in various models including hanging clamps, hanging bars, and wire mesh clips, with prices ranging from $10 to over $100 depending on type, material, and load capacity.

Types of Cable Tray Supports

1. Hanging Bars
   • Suspended from threaded rods, these bars support cable trays along their length.
   • Typically made of zinc-plated steel for corrosion resistance.
   • Can support up to 280 lbs per foot when spaced every 8 feet.
   • Threaded rods and nuts are usually sold separately (McMaster-Carr)
2. Hanging Clamps
   • Attach to the sides of a tray section and suspend it from threaded rods.
   • Provide secure support for straight or curved tray sections.
   • Ideal for wire mesh or solid trays, allowing easy adjustment and alignment.
3. Hanging Clips
   • Smaller clips attach to the tray sides and suspend it from 1/4", 3/8", or 1/2" threaded rods.
   • Lightweight and suitable for wire mesh trays or cable baskets.
4. Under-Desk or Office Wire Tray Supports
   • Designed for home or office cable management.
   • Usually metal or plastic, priced lower ($10–$30 per unit on Amazon).

Materials

• Zinc-Plated Steel: Good corrosion resistance, suitable for indoor and light industrial use.
• Stainless Steel (304/316): High corrosion resistance, ideal for outdoor or harsh environments.
• Plastic or PVC: Lightweight, halogen-free, and fire-resistant options for low-load applications.

Price Range

• Industrial Supports (Hanging Bars/Clamps): $50–$120 per support depending on size, material, and load capacity (McMaster-Carr).
• Wire Mesh Clips and Small Supports: $10–$40 per piece (Amazon).
• Custom or Heavy-Duty Stainless Steel Supports: Can exceed $150 per unit for high-load or specialized applications (Ekabel24, RS Components).

Considerations for Selection

• Load Capacity: Ensure the support can handle the weight of the cable tray and cables.
• Tray Type Compatibility: Ladder, wire mesh, basket, or single rail trays may require specific support types.
• Environment: Corrosion resistance is critical for outdoor or chemical-exposed installations.
• Installation Flexibility: Adjustable supports allow easier alignment and future expansion. For purchasing, suppliers like McMaster-Carr offer a wide range of industrial supports with same-day shipping, while Amazon provides smaller-scale or office solutions. Specialized vendors like Ekabel24 and RS Components provide high-quality, standards-compliant supports suitable for industrial and commercial installations .
