This Butler ridge vent package is used on the Butlerib II roof.
Each ventilator is 10 feet long and can be installed in a stand-alone or continuous fashion.
Butler ridge vents are available with optional operator packages that allow the ridge vents to be easily opened or closed manually from ground level inside the building.
Ridge vents are a great way to promote airflow in unconditioned buildings during the warmer summer months or to change out warm, humid air from manufacturing processes with cooler, dryer air from outside the building.
