Product Description

This is a kit to replace worn out power tubes in Bayliss Mk.7 Autovents, (except Mk.7 Super units). To replace one star washer (retainer) needs to be removed from one end only of the pin to allow the pin to be removed from the unit and allow the old cylinder to be removed. A replacement star washer is included as these are not reuseable, please retain all other washers removed. The power tube supplied in the kit is the original cylinder supplied by Bayliss and will get your Mk.7 Autovent up and running as good as new.

Arrived in good order and works a treat. These cylinders do wear out in time. One of mine (I have 4 units) packed up after 10 years of use so I have no complaints . It is good to know parts are still available .The Bayliss vent openers are of a very strong and simple design which works.

Great item if your window openers fail. they work out at about half the price of a whole new unit, and are easy to fit.

Great value, although in my case it took a bit of time to fit, my greenhouse vents are about 9 feet off the ground, and my stepladder is wider then the path so i spent more time playing with the stepladder than fitting the vent, will buy again though if i have to.

Worked fine! A little fiddly to install in our greenhouse.

Good replacement as the wax had gone on our others (10 years old) but could have really done with better fitting instructions.
