Replacement Spacer Kit for the Bayliss MK7 automatic vent openers.
Bayliss Spacer Set Includes
You can buy these direct from the factory in England, but they take forever to be delivered and when you include shipping it costs 40% more. Faster, less expensive, doing business in the USA; what part of that is there not to like. Combined with a new Power Tube this replaces every non-metal part of your Bayliss MK7 vent opener/closer and makes it brand-new again, just like when you first got it.
The Bayliss MK7 Replacement Spacer Set is required if you are replacing the Power Tube. I am glad I had these on hand because when I removed my old power tubes the spacers just fell apart. Everything went very smoothly on the rebuild and is a quick project. So pleased and they work great.
