What's in the box

If you ordered multiple fans, be sure to keep the components of each fan together. The fans each have differently rated
components that are not interchangeable.
The fan is shipped in multiple boxes. The large box contains the main fan unit, upper yoke (with beam clips and spacers), lower yoke,
extension tube (if 3 ft or shorter) with attached safety cable, winglets, controller, and mounting hardware. The long box contains the
airfoils. If the extension tube is 4 ft or longer, it will also be shipped in a separate box.
Note: Dashed lines indicate internal boxes. Drawings below are not to scale.
