The order came very quickly and was exactly what I needed.

The people at ACF were very helpful and reliable. I would highly recommend the Bayliss MK7 vent opener for a greenhouse. Easy to install. Set it and forget it!

Well made! The holes did not align with the old ones so new ones had to be drilled to fit the new vent openers, but this is to be expected. The vents work great and if the quality is the same as the old ones that I replaced, then it will be another twenty years before I have to do it again!!! Very satisfied!!!

Quick delivery, and easy to fit with clear instructions. Does exactly the job I need it to do: it works perfectly and has proved to be very stable in strong winds.

I was happy to find this greenhouse automatic vent opener at ACF. I had looked before without luck. They were a perfect replacement and work just great. Delivery was quick and nicely boxed. Will definitely use ACF again.
