e.

One threaded rod at a time, hold the
washers and plate in place on the rod,
and screw the rod into a spring nut, as
illustrated.

Notes:

1. Be sure to position the flanges

of the flat fitting plates in the
grooves of the unistruts.

2. Before tightening the nuts on

the threaded rods, ensure that
the end of each rod is screwed
in until it is flush with the
backside of the unistruts. This
ensures the rods are threaded
completely through the spring
nuts.

Tighten each nut firmly.

f.

Thread a 5/16-18 nut about 2” onto the
end of each threaded rod.

g. Slip a 5/16” split lockwasher, 5/16” flat

washer, and flat fitting plate (in that
order) onto each threaded rod.

5.

Mount the TWTA as follows:

a. Lift the TWTA into position on the

vertical pole.

b. Slip a 14” unistrut over each of pair of

threaded rods (upper and lower).

Note: Install the 14” unistruts with the open face toward the pole, as
illustrated below.
