The manufacturer specifies a black finish and identifies the kit separately from DIN-rail and panel mounting accessories. EtherWAN also lists KR-BK7800040 among the mounting options for selected EX73900E and EX78900R devices. It is a passive mechanical accessory and does not include an Ethernet switch, network interfaces, or electronic components. Exact bracket quantity, dimensions, material composition, mounting screw sizes, and maximum supported load are not confirmed in the available manufacturer specifications. Compatibility with individual switch variants and hardware revisions should be verified before installation.
