5. Install the threaded rods as follows:
a. Install two spring nuts in both 14”
unistruts mounted on the RFT.
Note: Ensure the spring nuts are
positioned over the outer holes in the
14” unistruts, as illustrated.
b. To install each spring nut:
(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 5.b.(1) through 5.b.(3) for each spring nut.
c. Thread a 5/16-20 nut approximately 1-1/2” onto each threaded rod. (This
will ensure that the threaded rods will extend beyond the spring nuts when
installed.)
d. Place a 5/16” split lockwasher, 5/16” flat washer, and flat fitting plate over
each threaded rod.
