3. Position the rotary latches (3) over the rear docking points (6). Check to be sure the rotary latches fit into the neck of the rear docking points as shown in Figure 3. This may require some gentle squeezing or spreading of the side plates.
You must hear a click to verify that the rotary latch is completely engaged.
4. Push the rear of the side plates downward and close the rotary latches by pressing the latch lever as far forward as it will go. You will hear a click when the latch is in place. If the latch does not easily close, do not force. Check the alignment again.
The docking points must be fully engaged. See Figure 2 and Figure 3 for correct engagement. If docking points are not fully engaged the rack could shift position or come loose during operation.
See Figure 4. If installing an optional Rack Light Kit (3), route wiring (2) as shown. Mount two clips (1, from that kit) in positions shown.
