2. Mark the position on the rack for installing the slide rail.
a. Make sure the bottom edge of the slide rail aligns with the middle of the narrower metal area
between holes, as shown in Figure 5.
b. Ea
ch rack post requires six screws to fix the slide rail. You only need to mark the uppermost
square hole and lowermost square hole for installation.
c. Mark the square holes at the same height on the other three rack posts.
One rack unit has three holes, the middle of which is an auxiliary installation hole, and the
other two are standard installation holes. You can distinguish them by the space between each
two holes. The space between a standard installation hole and an auxiliary installation hole is
larger than that between two adjacent standard installation holes.
