Letter are mounted as individual words on flat aluminum rails. They are attached with threaded aluminum bolts into in-line stud bosses. The rail can be painted or anodized. The backs of the letters can be unfinished (standard) or finished for an additional cost. This option is only suitable for letters up to 8" tall. Two rails are attached when letters are between 8 and 24 inches tall. See the Technical Drawing for more details.

The mounting option does not come with a mounting template. The customer must drill their own mounting holes in the rail and supply their own hardware to attach the rail to the mounting surface.
