Got 2 of these for my greenhouse vents. Easy to install and have been quite reliable.

I have a palram greenhouse and needed a way to auto vent when it gets to hot inside. My husband installed this for me. He said the instructions were not great but he's an ME so he could modify as needed to get it installed. It works great.Be patient with the install - it's not user friendly but can be done. Once it's installed - it has worked with no issues.

Ordered and received. Now I need a ladder climber to mount.. I will say I do not like the instructions… bigger print might help!

Was exactly as described, I love how it opens and closes the window in my greenhouse. I no longer have to worry about opening the window before it gets to hot.

They do work. The pin used for assembly is drilled in the worst spot possible but is workable. I will say the threads will strip out during high winds but being aluminum it is expected

These were a perfect fit for our 16x8 greenhouse. The installation instructions weren't much help, but this isn't rocket science. They are a little flimsy and light weight for the price, but they work great on our aluminum frame windows. I can't see them lasting very long on a wood framed window the way the joints are made.

They work! It's great not having to remember to run out and open the vents on your greenhouse manually.
