2.With the rail “channel” facing the center of the rack, connect the rail to the front facing column using a 10- 32 flathead screw (item 4) and the center clip- on nut on the front- facing column. Repeat for the rail on the opposite column. Ensure the rail channel faces the center of the rack.

If the rack has center- facing columns (Figure 1- 3), insert a 10- 32 pan head screw through the rail opening and clip nut (perpendicular to the front- facing column). Repeat for the rail on the opposite column.

3.On the rack’s rear- facing columns, insert clip- on nuts on the first and third holes between the EIA unit indicators that are at the same vertical position as the indicators on the front- facing columns.

4.Attach the rear brackets to the rail ends using two 10- 32 pan head screws (item 3) and two 10- 32 nuts with lockwashers (item 6) per rail. Adjust the bracket along the rail until the bracket end aligns with (covers) the rack’s rear- facing columns. Tighten the 10- 32 pan head screws to firmly connect the bracket to the rail and maintain the rail length.

Connect the rail brackets to the rear- facing columns using two 10- 32 pan head screws per column.
