Manual Vent Control

Do you live where it’s windy every day?  Or do you happen to be in the path of possible hurricane force gales? The Manual Vent Control is not only designed to lift the heaviest vents or skylights, it’s also the best insurance for your greenhouse in the high wind areas.  This Manual Vent Control makes it easy to adjust ventilation with precision, letting you quickly open or close vents as needed to keep plants comfortable. With a smooth-turning linear gear drive, you’ll have full control over airflow.  
Order these in conjunction with one of our two sized Extension Handle to suit your greenhouse and avoid any straining or stretching. See C3537 - choose 5 ft or 10 ft.
