Vertical bends in cable trays are typically available in 45° and 90° angles, with dimensions and materials varying by manufacturer and tray width, designed to maintain cable integrity and comply with standards.

Common Angles and Types

Vertical bends are used to change the elevation of cable trays while maintaining smooth cable routing. The most common angles are 45° and 90°, available as inside or outside bends depending on the direction of the turn. Some systems also provide vertical up bends for transitions between levels.

Dimensions

Width: Typically matches the tray width, commonly ranging from 50 mm to 750 mm for industrial trays. Standard widths for ladder-type trays include 12", 18", and 24".

Depth/

Height: Varies with tray type; for example, a 90° vertical outside bend may have a depth of 2" to 12. 5" depending on the tray system. Bend Radius: Radius is designed to prevent cable damage.

For ladder trays, the radius at the center of the tray width is often 9 inches for smooth cable transition.

Materials and Finishes

Vertical bends are manufactured from: Pre-galvanized steelHot-dip galvanized steelStainless steel (AISI 304, 316, 316L)Alu-zinc or powder-coated steel for corrosion resistance Standards and ComplianceCable tray vertical bends are designed according to: NEMA VE 1IEC 61537UL Classified (cULus)NFPA 70 compliance for metallic trays Accessories and InstallationVertical bends often come as kits including hardware for installation, such as bolts and splice plates. They are compatible with ladder, perforated, and solid-bottom trays. Proper installation ensures strain relief and smooth cable routing, preventing sharp bends that could damage cables.

Summary

When selecting vertical bends for cable trays, consider: Angle (45° or 90°)Tray width and depthBend radius for cable protectionMaterial and finish for environmental conditionsCompliance with standards (NEMA, IEC, UL)Installation hardware and compatibility with the tray system These specifications ensure safe, efficient, and code-compliant cable routing in industrial, commercial, and data center environments.
