Telect offers two different wall mount brackets for the 3 module ELF chassis (ELF-0000-2400).  The ELF-0000-0900 supports both vertical and horizontal mounting of the ELF chassis, but provides limited rear access to the ELF modules.  The 130084-1 wall mount bracket supports only a vertical mounting of the ELF chassis, but allows for complete rear access to the ELF modules.
