Grandio Greenhouse - Automatic Vent - Window Opener


* Free Shipping * One Year Warranty *

Automatically opens the roof vent and louver window when the temperature reaches 70F. 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.

Opens and closes windows easily! Made of steel and aluminum, no electricity needed.
Automatically activates at 70°F.
The opening and closing of the vent is gradual allowing just the right amount of air flow for cooling. Shipping Weight: 1 lbs

Winter Storage: Store it in a dry place and do not forget to lubricate particularly the piston rod before remounting in the spring. Check that the piston rod moves smoothly.
Do not allow the cylinder to freeze as it may cause damage.
