Note: The mounting rails that run vertically along the inside
edges of the front and rear openings of EIA rack
cabinets can be of two types:
•
“Wide” rails have holes spaced 0.5 in. (12.7mm)
and 1.25 in. (31.8mm) on centers, in a repeating
pattern. These rails are prevalent in Europe.
•
“Universal” rails have holes spaced 0.5 in.
(12.7mm), 0.625 in. (15.9mm), and 0.625 in.
(15.9mm) on centers, in a repeating pattern. Thus,
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 US.
ATTENTION: Failure to follow these warnings may
result in personal injury or damage to the panel
components.
