Specifications of vertical brackets for cable trays

Vertical brackets are designed to support cable trays securely, accommodate various tray widths, and allow fast, hardware-free installation.

Design and Compatibility

Vertical brackets are used to support cable trays in vertical orientations, such as wall-mounted or floor-to-ceiling installations. They are compatible with wire mesh trays 6 inches and wider, and for tray widths of 18 inches or more, two supports are recommended to ensure stability and load distribution . The brackets feature fold-over tabs that secure the tray without requiring additional hardware, simplifying installation and reducing assembly time .

Material and Standards

Vertical brackets are typically made from high-strength steel or other durable metals, often finished with powder coating or black paint for corrosion resistance and aesthetic integration with equipment . They comply with RoHS Directive 2011/65/EU and its amendments, ensuring material safety and environmental compliance . Depending on the manufacturer, brackets may also meet UL or CE standards for mechanical and electrical safety .

Installation and Support Considerations

• Mounting: Brackets can be attached to walls, ceilings, floors, or structural beams using appropriate fasteners. They serve as support elements connecting cable trays to the building structure .
• Support spacing: The distance between adjacent brackets should be calculated based on tray width, load, and cable weight. Proper spacing ensures mechanical stability and prevents sagging .
• Load capacity: Brackets are designed to handle the weight of the cable tray plus cables, with larger trays requiring multiple supports for even load distribution .
• Flexibility: Vertical brackets allow for height adjustments and can accommodate changes in routing direction, including vertical bends or T-pieces .

Practical Notes

Vertical brackets are part of a modular cable management system, allowing installers to adapt to complex configurations while maintaining safety and structural integrity. They are particularly useful in data centers, industrial facilities, and commercial buildings where vertical cable routing is required .

By selecting the correct bracket size, material, and support spacing, vertical brackets ensure secure, compliant, and efficient cable tray installations.
