Figure 15. Using Template to Mark Vertical Rails
3. At the front of the rack cabinet, position one of the slide assemblies so that its
mounting-bracket flange fits between the marks or tape you placed on the rack,
marking the upper and lower edges of the template (see Figure16). The hooks
on the bottom of the mounting bracket should enter the holes beside the lower
marks you made in the vertical rails.
4. Secure the front of the mounting-bracket flange with a 10-32 x 0.5-inch pan-head
Phillips screw in the front vertical rail (see Figure16).
5. Push back on the back mounting-bracket flange until the mounting hook locks into
the matching square hole on the back vertical rail.
6. Repeat steps 3 through 5 for the remaining slide assembly on the other side of
the rack.
