The Patterson High-5 sports a newly redesigned 43" frame, suited for buildings with lower ceiling heights. It includes an updated clamping mechanism which facilitates easier and quicker installation; place the clamp over the beam and adjust the bolts. The High-5 generates a breeze during the warmer months, producing a 6-8 degree cooling effect, and promotes de-stratification through the colder months, making it a great solution for saving energy on utilities. Available accessories include 2-10' drop rods and purlin kits for easy suspension. 15-Year limited warranty: your choice of the installer still maintains the warranty.
