Wall-Mount Bracket Allows Installation of a Rack-Mount Device Without a Rack. This SmartRack® 4U rack bracket is recommended for home offices and small businesses with a need for rack-mount equipment, but no available space on the premises for a standard wall-mount rack. The SRWALLBRKT4UKD provides open and unrestricted access to equipment and cabling, and hangs flush against the wall for unrestricted out-of-the-way access. It ships in an unassembled “knock down” version. Attaches to the Wall with User-Supplied Hardware. Made from heavy-duty cold-rolled steel with a durable black powder-coated finish, the SRWALLBRKT4UKD easily mounts to the wall of your back office or closet with user-supplied hardware. Wall-mounting holes are spaced 16 inches part to match standard wall-stud placement. You can also install the bracket horizontally beneath a desk or workbench for instant access. Compatible with Standard 19 in. 2-Post Rack Equipment. Hardware is included for mounting 4U rack equipment. The bracket’s horizontal mounting rails support square-hole mounting. The maximum load capacity is 175 pounds (79.4 kilograms).
