Bayliss MK7 Replacement Power Tube

Finally, I changed the Bayliss MK7 replacement tube. Replacing was surprisingly Easy and straightforward, Working Good, just in time for our 90 degree weather.

ACF Greenhouses was the only place I could find a replacement tube. I had some MK7 Bayliss auto openers but they were stored in the heat for a long time before installation and didn't seem to work properly. I read that it might be the tube. I ordered replacements and swapped them out, and now they work! Saved $ just replacing the tube compared to the whole thing.

We live in northwest Oregon and don't get high daytime temperatures this time of year. I wanted to keep the vents closed a little longer and target a daytime high temp inside the greenhouse around 85 degrees to counteract the nighttime temps in the mid 40s. This "orchid" opener does the trick. I rated it 4 stars because there is a single use disk that you must remove to swap out the openers. I would like to see a pin that could be removed as needed.

The Bayliss MK7 power tube works great. I ordered two for my greenhouse. They are very easy to install. If you ordered these then you must order the Replacement Spacer Set. Shipping was fast too!

When my 20 year old greenhouse vents stopped opening I thought I was in for a works of hurt and expense to fix them, not only did they have the exact parts I needed, they were inexpensive, shipped quickly and I was back up and running in a half an hour. Thanks!
Instructions were spot on as well!
