Automatic Greenhouse Side Louvre Opener

As the title. Well built, simpler to fit than I expected and works well. Only thing I changed was the plastic 'pin' which connects the vent arm to the push rod - I was finding when it was 25 degrees + the plastic pin was bending and the securing cap came off which the stopped the louvres closing. Replacing the pin with a thin bolt and nut kept operation the same and overcame this problem

Purchased 2 openers...very pleased with 1st opener, had to drill out 2 rivets from existing handle, & drill a couple of small holes for new opener. Working perfectly! Couldn't fit 2nd opener as tomatoes were in the way...have to wait till autumn...lack of planning!

Have fitted two to a Vitavia Phoenix greenhouse - easy to fit - working very well. Only issue is that the lever falls off the pin occasionally, possibly because of some alignment issue. However, this is easy to fix with a small bolt or split pin. update Easter 2020 - still working perfectly

Doesn't fit my greenhouse uprights

Easy to fit. Only complaint is that the plastic "glass" is a bit too flimsy. I live in a very windy place so I think I might get some glass cut. Mechanism works very well. I did have to make a small adaptation for my polytunnel.

Fitted this automatic louvre opener, to my Halls greenhouse louvre windows, some weeks ago and it is working well. The biggest problem was removing the old seized screws that held the original manual leaver to the actuator mechanism. I had to drill them out. Once done the fitting was easy enough and so was adjustment. I would buy this product again and from the supplier.

This is great value for money and fairly simple to install, saves having to rush to open windows/vents as once set these are very reliable.

Fast service & excellent, well made opener. Working well.

Put this on the window this spring.It works great already.This should help with a summer cross breeze to cool off our greenhouse.

Does not attach very well, there are much better ones avaiable.
