7. Follow the same steps as in #1 through #6 to the second RK-UNIV
receiver shelf, but start on the opposite side of the shelf as shown.
This is so when the shelf is turned upside-down during mounting the
divider spacing will line up properly.
Rear Retaining Bracket Placement
This step can be done after the rack has been mounted, but there will
be situations that may require this step to be done before mounting.
1. When installing the Rear retaining bracket, line up the mounting
studs on the bracket to the elongated holes that are located on the
rear half of the shelf.
2. Place the bracket so the 90º bend in the bracket is closest to the
rear of the unit being racked.
3. Keep in mind the front of the receiver should not extend passed
the mounting tabs on the front of the shelf, as this is critical for
proper mounting in the Head-End rack.
4. Slide the bracket up to the rear of the receiver. Make sure the
bracket is properly aligned and press in the snap pins.
