Wax filled vent openers?

Lewiston, CA(Zone 7b)

Well, I have a new GH going up. It's down at the bottom of our property where there is no power (yet)
I have been looking for the auto (Temp controlled) arm to open the vents. I'm having a heck of a time locating any. I thought this would be the place to ask.
I have tried most of the places you find in the backs of the Mags.
Here's what it looks like now.
Thanks for any leads. Bj

If you don't find what you are looking for , I bought some from a place in England. and I[ may] be able to find the name and address for you, [if you dont find what you are looking for].

About 2 years ago, I was at this great garage sale & there were 2 of them laying there, I didn't know what they were, they were $5, still packaged!!!!
I was not into GHs then, darn! I did get heating cables & some other garden related stuff.
I think both of those sites have what I'm looking for. Thankyou, though.

You can also buy them from riongreenhouse.com I do not know if they are different in any way.

I have two from Lee Valley installed two years. They are adjustable and work perfectly. Both open together on the temperature rise. These were made in England. Al

You can get vents that open and close automatically with the temperature.
Check out Charley's Grenhouse on line. They have loads of supplies for
greenhouses-hence the name
