High-Resiliency Spider Bracket Helps You Create Custom Cable Management Schemes The SmartRack® SRWBSPDRBRKT is a black powder-coated metal bracket for easy installation of your wire mesh cable tray. This bracket allows you to mount straight sections of cable tray to the wall or floor of your data center, network closet or industrial space and extend your cable management application. It mounts to the wall or floor with user-supplied hardware and then effortlessly snaps into the wire mesh. For best practice when wall mounting, additional support on the other side of the tray section is recommended.
