Wall brackets of cable tray are essential components in cable management systems. They are used to support cable trays on walls, ensuring that cables are organized and protected from damage. In this article, we will discuss the different types of wall brackets available in the market, their features, and how they are used.
Types of Wall Brackets
There are several types of wall brackets available for cable trays, including:
1. Standard Wall Brackets: These brackets are the most commonly used and are designed to support cable trays at a fixed distance from the wall. They are available in different sizes and materials, including galvanized steel, stainless steel, and aluminum.
2. Adjustable Wall Brackets: These brackets are designed to provide flexibility in the installation of cable trays. They can be adjusted to different angles, allowing for the installation of cable trays on uneven surfaces.
3. Ladder Rack Wall Brackets: These brackets are designed for use with ladder-style cable trays. They are available in different sizes and can be used to support cable trays at different heights.
Features of Wall Brackets
Wall brackets of cable tray come with several features that make them suitable for different applications. Some of the features to consider when choosing wall brackets include:
1. Material: Wall brackets are available in different materials, including galvanized steel, stainless steel, and aluminum. The choice of material will depend on the application and the environment in which the cable tray will be installed.
2. Load Capacity: Wall brackets come with different load capacities. It is important to choose a bracket with a load capacity that is suitable for the weight of the cable tray and the cables it will support.
3. Adjustability: Adjustable wall brackets provide flexibility in the installation of cable trays. They can be adjusted to different angles, allowing for the installation of cable trays on uneven surfaces.
4. Corrosion Resistance: Wall brackets made of galvanized steel or stainless steel are resistant to corrosion and are suitable for use in harsh environments.
