Which of the following is not a type of cable support?

A patch panel is not a type of cable support. Patch panels are used in telecommunications and data networking to manage and organize multiple connections, allowing for easy access to connect and disconnect cables. They serve as a central point where incoming and outgoing lines can be patched through, providing functionality for the network rather than directly supporting or holding the cables in place.

In contrast, cable trays, fasteners, and anchors are specifically designed for supporting cables. Cable trays provide a structural system to hold and manage running cables, facilitating proper organization and airflow while protecting the cables. Fasteners, such as cable ties or clips, are used to bundle and secure cables to prevent movement, while anchors are used to secure cables to walls or ceilings, ensuring that the installation remains stable and organized.
