Magnetic cable tray brackets are becoming increasingly popular due to their ease of installation and ability to eliminate the need for drilling. These brackets utilize strong magnets to secure the cable tray to metal surfaces, such as beams or walls. When it comes to installing cable tray brackets, drilling holes is the traditional and most commonly used method. They come in various forms, including ladder trays, solid-bottom trays and wire mesh trays such as stainless steel wire cable trays.
