High-Resiliency Wall Bracket Helps You Create Custom Cable Management Schemes The SmartRack® SRWBWALLBRKTLD is a black powder-coated metal bracket for easy installation with your wire mesh cable tray. This light-duty horn bracket allows you to mount sections of cable tray along the wall of your data center, network closet or industrial space to complete your cable management application. It mounts to the wall with user-supplied hardware and then easily snaps into the wire mesh. It is compliant with small, lighter-load cable tray sections, such as Tripp Lite's SRWB6210STR. For best practice, tray support is recommended approximately every five feet.
