To attach the mounting brackets to the front vertical rail:
1. Remove a long mounting bracket, two screws, and a bar nut from the kit. See the
following figure for a view of how to place the bar nut in relation to the mounting
bracket and vertical rail.
2. While facing the front of the rack, orient the mounting bracket so that the short side
with the four mounting holes is facing toward the outside edge of the vertical rail and
the bracket extends to the back of the rack.
3. Place the bracket on the mounting holes in the vertical rail.
4. Insert a screw through the marked top hole in the vertical rail and through the top hole
in the mounting bracket. Place a bar nut on the screw, and loosely tighten it. Repeat for
the marked bottom hole.
5. Install the other front mounting bracket in the same manner.
