Stovax 4" 100mm Stove Flue Damper Butterfly

Well pleased with the product

really good quality

This was exactly what I expected, however it was not obvious how to fit it in a pipe. I rang the supplier and they did not know, but gave me the phone number of Stovex's tech support department. Unfortunately they did not know how to fit it either. So I had to work it out for myself.
