Works perfect to adjust the temp in the greehouse. I don't know what the magic is behind the mechanism, but it was able to help keep the temp stable through the summerRead More
great and work well
Mine didn't really come with anything to speak of making adjustments according to temperature and width of opening, so I just experimented until I got what I wanted. They do work very well to open the windows without being one more thing for me to have to attend to, so well worth the cost. Do be very careful and attentive during installation though, as during assembly, one snapped shut while I was holding it and nearly guillotined my finger tip off, which was quite painful and quite messy and put me out of working on my greenhouse until it healed.Read More

"Why did you choose this product?"
I've been researching greenhouses and had planned to purchase it from Greenhouse Megastore but decided to check out your site prior to placing the purchase. So glad I did as I was able to purchase the anchor kit, window auto vents, and shelves for only slightly more than the greenhouse itself from the Greenhouse Megastore. Thank you so much.
NEEDED FOR MY GREENHOUSE
I've had a greenhouse in another state and had no vent on it, this is needed to let some of the heat out.
"Do you get the arm and the piston? What does the kit include? Is it a wax piston? What is the lifting capability?"
Hello my1screenname, yes this comes with a wax piston that can lift 2 pounds. Have a great day!
