What component is used to secure cables at corners?

The correct choice indicates that corner or pull components are specifically designed to manage and secure cables at corners, ensuring they are properly held in place without undue stress. When cables make directional changes, such as at corners, it is essential to use devices that allow for flexibility while also preventing damage to the cables. Corner or pull components provide this solution by enabling a smoother transition for the cables, thereby maintaining their integrity and functionality.

In the context of cable management, these components not only secure the cables but also facilitate easier access for maintenance and installation. This is crucial in outside plant environments where durability and reliability are paramount.

While other options mention different components commonly found in cable management systems, they do not serve the specific purpose of managing cables at corners in the same effective way.
