4. Attach the Extension Tube
Fasten the extension tube to the upper mount with the Extension
Tube Hardware. Ensure the extension tube is hanging plumb to
the ground, and then tighten the hardware so that it is snug, but
not fully tightened.
Note: If the mounting structure requires a non-standard length
of extension tube, see “Cutting the Extension Tube.”
Extension Tube Hardware:
a. (2) 1/2-13 x 4-1/2’’ GR 8 Bolt
b. (4) 1/2’’ Flat Washer

5. Secure the Safety Cable
ATTENTION
The safety cable is a crucial part of the fan and must be installed correctly. If you have any questions, call
Customer Service for assistance.
Note: If your fan installation includes an extension tube, the safety cable is already attached to the extension
tube. If you are mounting the fan without an extension tube, the safety cable is packed separately.
I-Beam mount
Secure the safety cable by
wrapping it around the I-beam and
connecting the looped ends with
the shackle as shown. The cable
must be drawn tightly around the
I-beam, leaving as little slack as
possible. If possible, the shackle
should be on the topside of the
I-beam. Securely tighten the
shackle.
Angle iron mount
(with extension tube)
Secure the safety cable by
wrapping it around the angle
irons and connecting the looped
ends with the shackle as shown.
The cable must be drawn tightly
around the angle irons, leaving
as little slack as possible. If
possible, the shackle should be
on the topside of the angle irons.
Securely tighten the shackle.
Angle iron mount
(no extension tube)
Route the cable through the motor
frame and around the angle irons
as shown. Connect the looped
ends of the cable with the shackle.
The cable must be drawn tightly
around the angle irons, leaving as
little slack as possible. If possible,
the shackle should be on the
topside of the angle irons. Securely
tighten the shackle.
