4. Install the shelf (C in Figure 6 on page 19), using these steps:
a. The shelf can be adjusted to a length of between 27 and 31 inches (68.58
and 78.74 cm) to match the cabinet size. To lengthen or shorten the shelf,
loosen by approximately 1/2 turn the four 6-32 screws in the four slots on
the shelf (I-4 through I-7 Figure 6 on page 19) and adjust the shelf to the
desired length.
Note: We recommend two people for the installation of the shelf, one at
either end of the cabinet to support and align it correctly while
attaching it to the cabinet.
b. Tilt the shelf at an angle to fit it between the rails, and then position it
horizontally and level with the shelf mounting tabs on the outside of the
cabinet vertical rails, and aligned with the clip nuts you installed earlier.
c. Secure the shelf to the cabinet with eight 10-32 screws with washers (E in
Figure 6 on page 19), two screws in each corner of the shelf (see Figure 8 on
page 22). Tighten screws according to specifications under “Torque
requirements” on page 20.
