Voyager Easytrack 4 Wall Mount SystemThis is actually a Voyager Easytrack 4 Post system and we include 4 wall mounts to eliminate the posts.
The 4-corner Wall-Mount Track System mounts directly to wall-studs. Offers the same coverage area as the 4-Post configuration, but without the Posts. Full coverage anywhere within the 4 corners.
The 4-Post system acts like an x-y system for greater coverage.
