Crossbeam, lower it into the tops of the
Columns. If not, the Columns will have to be
placed horizontally, in order to install the
Crossbeams into the Columns. Then, the entire
end structure (two columns and crossbeam) will
need to be stood up as one.
11. Unpack the Lock Ladders (#11) (Fig. 5) from the
package and slide them into the precut slot on
the Rub Blocks (#67) inside each column. After
removing the top Nut from the Lock Ladder, you
are ready to install the Top Caps A&B (#10 &
#65) on the columns.

’s Top
Caps. Arrange Top Caps so that the cable
mounting holes are closest to the runways. Use
provided Bolts, Nuts, Washers and Lock
Washers to install Top Caps, as shown in Fig.5
& 5b.
