6.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 Figure 1-17).
The hooks on the bottom of the mounting bracket should enter the holes beside the lower marks you made in the vertical rails.
7.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 Figure 1-17).
8.Push back on the back mounting-bracket flange until the mounting hook locks into the matching square hole on the back vertical rail.
9.Repeat steps 6 through 8 for the remaining slide assembly on the other side of the rack.
