Cable Basket Trays get their name from the fact that they look like long baskets made of wire. Basket trays can be mounted along walls, suspended from the ceiling, and even run below raised flooring that’s often found in data centers and other facilities. Their “open” structure allow air to easily flow through and ensures that cables stay well-ventilated and cool, preventing heat related malfunction. Typically, they’re made of steel, and come in different finishes, including powder coat and zinc plating.
