The safety cable is a crucial part of the fan and must be installed correctly. If you have any questions, call Customer
Service at 1-877-BIG-FANS 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.

possible. If possible, the shackle should
be on the topside of the I-beam. Securely
tighten the shackle.
