Cable tray hangers are essential components for supporting cable trays, and their specifications include material types, load capacities, and installation guidelines.

Key Specifications for Cable Tray Hangers

1. Material:
   • Cable tray hangers are typically made from materials such as steel, aluminum, or plastic. Steel hangers are often galvanized for corrosion resistance, while aluminum offers lightweight and corrosion-resistant properties .
2. Load Capacity:
   • The load capacity of cable tray hangers varies based on design and material. It's crucial to select hangers that can support the total weight of the cables and the tray itself. Specifications often include load classes, such as 50 lbs/ft, 75 lbs/ft, or 100 lbs/ft, which indicate the maximum load the tray can support over a specific span .
3. Dimensions:
   • Hanger dimensions should match the cable tray width and height. Common dimensions include 2 inches by 4 inches for wire basket trays, but this can vary based on the specific tray type and application .
4. Installation Guidelines:
   • Proper installation is critical for safety and functionality. Hangers should be installed at regular intervals, typically every 10 feet for ladder trays, and should be secured to structural supports like walls or ceilings .
5. Compliance Standards:
   • Cable tray systems, including hangers, must comply with industry standards such as NEMA VE 1 for metallic cable tray systems and NEC (National Electrical Code) for electrical installations. Compliance ensures safety and reliability in installations .

Additional Considerations

• Types of Hangers: There are various types of hangers, including J-bolts, strut channels, and brackets, each suited for different installation scenarios and cable tray types .
• Environmental Factors: Consider the environment where the cable tray will be installed. For outdoor or corrosive environments, select hangers with appropriate coatings or materials to prevent degradation . By adhering to these specifications and guidelines, you can ensure that your cable tray systems are safely and effectively supported, facilitating efficient cable management in your installations.
