GK-Vent, Automatic Vent Operator
Automatic vent operators on the roof and base vents require no electricity or batteries. The vent operator contains a paraffin (wax) that expands when the temperature reaches about 65 deg.F. As it cools and the paraffin contracts, the operator's springs draw each vent closed. It is adjustable within approximately 5 deg.F and easily detachable for manual operation.
The Automatic Vent Opener will open and close frame lids and top-hinged greenhouse vents up to 15 lbs. It is fully adjustable to open from 60 deg.F to 77 deg.F and the maximum opening height of 18 inches is reached at 86 deg.F.
$44.50.
