    ..and maybe take the glass out before drilling to be on the safe side. (I'm a coward so did that)

      Generally if you have a common make of greenhouse the Agros and Homebase autovents should fit. However you might find that the holes in the greenhouse strut are not correct, at which point you would have to drill new hole. While awkward, this is not difficult, do remember to use a drill bit appropriate to the job.
      ...like a High Speed Steel (HSS) twist drill to drill through the frame (aluminium or wood, makes no difference). And do take the glass out first, it will shatter if you do try and drill it with one of these.

      "Agros" - seems a much more appropriate name than "Argos"!

        I've got two on my greenhouse roof and could'nt do without them. The sun shines on the greenhouse first thing in the morning and one of them is usually open if i am not up early.
        I also have double doors which also help the flow of air.

        And when your back stops aching,
        And your hands begin to harden.
        You will find yourself a partner,
        In the glory of the garden.

          They are fantastic, and well worth the money.

          One thing I've noticed with mine is that there is a significant delay in the speed with which they work. On a sunny morning th temperature has reached 25C before mine start to open. During the day they are fully open at anything above 22C, and in the evening, the temperature can be down at 10C before they are fully closed.

          Worth keeping an eye on when you try to get the opimum temperature to set them at...

            I suppose that would be due to the material in the piston taking time to warm up from cold and then cool down - what is in the pistons, is it oil?

              The one I have on my louvre wasn't working properly the other year and I went to buy a new one. Fortunately DIY shop didn't have any in as OH attacked the old one with a can of WD40 and it's been fine ever since so am guessing that you should service them now and again!

              Some of us live in the past, always talking about back then. Some of us live in the future, always planning what we are going to do. And, then there are those, who neither look behind or ahead, but just enjoy the moment of right now.

              Which one are you and is it how you want to be?

                  We fitted our second one last night. Fitting the first one caused enough rows that Kofi Annan had to be brought in to mediate. Eventually we got it on and it works beautifully.

                  You'd think we knew what we were doing fitting the second ! (even Kofi wasn't taking our calls).

                  I now have a strategically placed wad of bubble wrap stuck to the pane with uv/weather resistant tape to stop it banging against the pane of glass. I fully expect to come home from work tonight finding a million bits of (toughened) glass all over the toms. The weight of the first one seemed to be enough to pull it off the glass. I think the triple spring in the second is that bit stronger that it won't "drop".

                  I have a well known make of greenhouse (Hall's), and these were a well known brand of auto vents (Bayliss). I shall be writing to both manufacturers and suggesting they talk to each other about getting the damn holes to even vaguely match.

                  (note to self: must remember to loosen the net shading over the new side to allow for expansion).

                  I'm sure they are wonderful inventions but they won't get the Nobel Peace prize from me this year.

                      I would have loved to have seen that !

                      On the up side, the vent was open when the OH got home (I was up the lottie), and no broken glass ......... yet!

                        That's some tough stuff

                        OT: I have an automatic window and it really is invaluable. Not sure where it came from or how much it cost though as I was given my Greenhouse by my nextdoor neighbour.
