c. With the RFTs side by side,
position a 20” unistrut
(open side facing up) in
place over one pair of 8”
unistruts.
Ensure the long unistrut is
centered over the RFT.
d. Using two or three 5/16-18
bolts, 5/16” split
lockwashers, and 5/16” flat
washers, attach the 20”
unistrut to the 8” unistruts.
Tighten the bolts firmly.
e. Attach the second 20” unistrut to the second set of 8” unistruts by repeating
Steps 3.a. through 3.d.
4. Install the pipe blocks as follows:
a. Install two spring nuts in each of the two 20” long unistruts and two 14” long
unistruts (centered in the unistruts, and wide enough apart so the pipe blocks
will clear the pole when the unit is installed).
b. Install each spring nut as follows:
(1) Place the spring nut in the unistrut channel, spring side down, with its
wide side parallel with the unistrut channel.
(2) Press down on the spring nut to compress the spring, and rotate the nut
90
°
(i.e., perpendicular to the unistrut).
(3) Release pressure on the spring nut.
(4) Repeat Steps 4.b.(1) through 4.b.(3) for each spring nut.
