I tried to make this Fancemot Greenhouse Vent Automatic Opener work in my greenhouse. My greenhouse has glass windows with aluminum frames. The glass is too close to the opening, for these to be mounted, as per the included instructions. I tried several different things to use these, but the only way I will be able to use them is to replace the glass in two windows, with plexiglass, wood, or some thin polycarbonate. This is my fault, not the fault of the auto openers. They are well built. They come with all the needed hardware, and they do work. Each opener has one powerful spring. I thought the instructions were a little confusing, for how to put them together.
