Easy to use, easy to install
Small but durable item that is easy to install, good to adjust and controls the airflow in your flue pipe very well.

Close but no cigar.
The damper is fitted and working well. However , not until I put it in a vice and adjusted the angle of the handle, this was needed to prevent the spring from slipping off of the shank and rendering the whole thing useless.

A must have for long flues
Fitted this in 10 minutes and the extra control on flue draw is brilliant, would definitely recommend

Great product
Great product, make sure you get the holes level when installing. Bit of a pain to remove once it's in and you need to sweep the flue. Gives an extra level of fire damp if you have a burner that won't fully shut down or live in a windy area.
