Internal fixing brackets for vertical cable trays

Internal fixing brackets are designed to securely mount vertical cable trays to walls or structures, providing stability, corrosion resistance, and compatibility with standard tray systems.

Overview

Internal fixing brackets are essential components in cable support systems, particularly for vertical installations. They mechanically support cable trays, ensuring that cables are safely routed and organized while maintaining compliance with standards such as DIN EN 61537 . These brackets are typically used in industrial, commercial, and internal electrical installations.

Types and Features

• Wall and Support Brackets: Designed to attach vertical cable trays directly to walls or structural surfaces. They can be single or paired for additional stability .
• Suspended Brackets: Used when vertical trays need to be supported from ceilings or beams, often with threaded rods or RSJs .
• Mounting Plates: Allow attachment of junction boxes or electrical devices to the cable tray system .
• Electro Zinc (EZ) Coated Brackets: Provide excellent corrosion resistance for internal environments, suitable for wire basket trays or solid walls .

Materials

Internal fixing brackets are commonly made from steel or stainless steel, with galvanization or electro zinc coatings to enhance corrosion protection . Stainless steel grades like AISI 316L are used in environments requiring higher durability and resistance to chemical exposure .

Installation Considerations

• Support Distance: The spacing between brackets should be calculated based on the tray load and cable weight .
• Compatibility: Brackets must match the cable tray type (solid, ventilated, or wire mesh) and size.
• Load Capacity: Ensure brackets can support the combined weight of the tray and cables, including any dynamic loads.
• Internal Environment: For indoor installations, electro zinc or galvanized finishes are sufficient, while outdoor or harsh environments may require additional protection .

Suppliers and Customization

Manufacturers like Haley Products Ltd offer a wide range of internal fixing brackets for vertical cable trays, including standard and custom designs to simplify installation and reduce downtime . Orders can be tailored for specific wall, ceiling, or beam mounting requirements.

Summary

Internal fixing brackets for vertical cable trays are critical for safe, organized, and durable cable management. Selecting the right bracket involves considering material, coating, load capacity, compatibility with the tray system, and installation environment. Properly installed brackets ensure compliance with standards and long-term reliability of the cable support system .
