Collars for Wall-Mount Exhaust Fans
Connect your wall-mount exhaust fan to a louver. One side of the collar fits around your exhaust fan and the other includes a flange for mounting a louver. Overall height and width include the mounting flange.
Note: To be compatible with the fan, the collar must be larger than the overall fan dimensions. To be compatible with the louver, the collar's For Louvers That Fit Opening Height and Width must match the louver's For Opening Width and Height.

Wind-Driven Roof-Mount Exhaust Fans
Designed to spin freely with the slightest breeze, these fans create a vacuum that draws air out from buildings and ventilation systems—no electricity required. They are also known as turbine ventilators. Mount fans on your roof away from wind obstructions.
Optional mounting bases are sold separately.
All bases have a square bottom, round top, and flashing to simplify installation.
To Order: For slope bases, please specify pitch: 1/12-11/12 in increments of 1/12. To determine pitch, use an angle indicator or divide rise by run (see illustration). For instance, if your roof rises 5" in 12" of horizontal space, your pitch is 5/12.
