Okay, rack hole spacing can look a bit odd. Obviously, each rack unit
is approximately 1.75". within each rack unit, you will have either 2
or 3 screw holes (top, bottom, and optionally middle). The gap between
the bottom hole and the top of the next rack unit will be a small gap.
The middle hole will be equidistant between the top and bottom holes
within a rack unit.
Lets see if a diagram makes it more obvious
o
^ o <- top hole
|
1.75" o <- optional middle hole
|
v o <- bottom hole
o
Hope that makes some sense,
Simon
