Mounting Rail
IMPORTANT The mounting rails that run vertically along the inside edges of the front
opening of an EIA-rack cabinet can be of two types:
• Wide rails have holes spaced 12.7 mm (0.5 in.) and 31.8 mm (1.25 in.) on
centers, in a repeating pattern. Wide rails are prevalent in Europe.
• Universal rails have holes spaced 12.7 mm (0.5 in.), 15.9 mm (0.625 in.),
and 31.8 mm (1.25 in.) on centers, in a repeating pattern. The universal
rails have a hole pattern that contains the wide pattern but provides an
additional hole at the midpoint of the pattern. Universal rails are most
prevalent in the United States.
