This metal channel runs the length of the map and serves two purposes. First, It
is a firm and solid mounting for the roller brackets. Second, the metal channel has a groove that
slides over the round "buttons" you can see on the
map rack below. The result is a
rack system that lets you mount 2 rollers for maps of different widths. This is
a truly versatile system and using solid steel construction, built for years of
heavy classroom use. See a close-up of the rack See the 4 map Rack Return to the wall map page
