Extra fast and accurate mounting of video rows. Using one long mounting rail rather than several small ones allows you to mount SMS Multi Display Wall modules faster, and perfectly aligned. The long rail has an additional advantage where it is necessary to fix mounting screws in wall beams, since it will cover more beams. This makes it easier to find the locations of a sufficient number of beams for safe mounting. The product consists of either one rail of length 2000 mm, or two rails of length 2000 mm, on which Multi Display Wall modules are mounted as required. The rails are made of aluminium and can be cut and combined freely.
