    • A little difficult to install but works great
      Verified Purchase

      We installed this in my Palram 8x8 Snap and Grow greenhouse. I had read some reviews that stated that it did not fit correctly when trying to install it. Most people used a Dremel to shave down part of the opener to make it fit. We had to do the same and I was worried that it might not open the window now. The first day that the sun came out, I looked outside and the window was open. That evening I watched as it went back down. Love this thing!

    • Q:

      "Why did you choose this product?"

      • A:

        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.

      • A:

        I've had a greenhouse in another state and had no vent on it, this is needed to let some of the heat out.
