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.
