Worked perfectly. Took a little working out how best to fit them but once sorted proved very easy to fit and are working as supposed. Many thanks. Donald Stewart

I'm so glad I bought this item - I wish I had done it years ago ;-)The Bayliss product appears a bit flimsy, although they do a more robust high-wind version, but it seems to be doing the job well and was easy to fit once I had read the instructions.It vents the glasshouse well before I manage to get out there!
