Features & Specifications
Automatically opens and closes Roof Vent when temperature changes. The opener has a metal cylinder containing a mineral which expands when heated. This pushes a piston that opens the vent. As the temperature cools, the mineral shrinks and a spring closes the vent and resets the piston. The opening and closing of the vent is gradual, allowing just the right amount of air flow for cooling.
(please note, $9.99 shipping will be added to this item if not purchases with a Rion greenhouse)
