Types of 45-degree bends in cable trays

Yes, 45-degree bends for cable trays are readily available in multiple sizes, materials, and configurations for light, medium, and heavy duty systems.

Availability and Types

45-degree bends are commonly offered as flat bends, horizontal elbows, and vertical inside bends. They are designed to provide smooth directional changes while maintaining continuous cable support and proper routing through the turn . Adjustable bends are also available, allowing configurations of 30°, 45°, 60°, 75°, and 90° for medium and heavy duty trays up to 300mm wide .

Materials and Finishes

These bends are manufactured in a variety of materials to suit different environments:

• Mild steel pre-galvanized (PG)
• Mild steel hot-dip galvanized (HDG)
• Stainless steel grade 1.4404 (316L) for corrosion resistance . Some products, like the CleanTray 45-degree elbows, are made from SS304 stainless steel with a brushed finish, suitable for applications requiring frequent washdown .

Sizes and Standards

Standard widths range from 50mm to 900mm, with common manufactured radii of 12", 24", or 36" depending on the tray system . These bends comply with NEC, IEC, and NEMA standards for safe cable routing, and calculators are available to determine proper bend dimensions, centerline arc lengths, and offset distances for specific installations .

Additional Features

• Ventilated or closed covers are available for 45-degree bends .
• Ladder rack curved sections provide vertical plane changes in addition to horizontal bends .
• Pre-galvanized steel vertical inside bends are also offered with specific side rail heights and widths for larger cable trays . In summary, 45-degree cable tray bends are widely available in multiple configurations, materials, and sizes, making them suitable for a variety of industrial, commercial, and specialized applications. Proper selection should consider tray width, material, bend radius, and compliance with relevant electrical standards.
