(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 inch (38 mm) onto each threaded

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

inches (5.1 cm) onto the end
of each threaded rod.
g. Slip a 5/16 inch (8 mm) split
lockwasher, 5/16 inch (8 mm)
flat washer, and flat fitting
plate (in that order) onto each
threaded rod.
