Mirror ganging kit is needed to ensure flush alignment. It is only used when you wish to gang a Profiles Mirror between cabinets and/or lights, creating the proper spacing and depth for the mirror.
When ganging Profiles Lighting solely with a Profiles Wall Mirror, the mounting blocks on the Profiles Light must be removed and the mirror ganging kit will need to be installed. Ganging Kit can be used in recessed or surface mounted installations.
Allows for clever grouping when storage is not needed and to achieve a certain visual effect.
