Abstract: A wall mount assembly is provided for attaching an electronic device to a slat wall. The wall mount assembly includes a main body, a mount and a pair of clip assemblies to connect to the slat wall. The mount has a central opening to receive a support arm that holds the electronic device. The clip assemblies may be spaced apart on arms attached to the main body. The arms and main body are dimensioned so that electrical cables connected to the electronic device can be passed between the main body and the slat wall, providing cable management. Furthermore, a wall mount assembly kit may include assorted clips or brackets for attaching to different slat wall configurations.
