Rockford Chimney Supply RockFlex Stainless Steel Smooth Wall Chimney Liner Tee Kit, 6 Inch x 25 Feet

Had two separate chimney sweeps tell me the liner I bought was the same one they install with the same warranty.

No instructions included.

This was a lot of work to install by myself, but once in the chimney has proven the best upgrade I could have made to an aging heating system. Used a different topper for windy conditions. The liner is stiff, yet flexible enough you can feed it into the chimney from the top down with a little bit of back and arm muscling. Once in place, strapping the cap and topper was very simple and made for quick work of the project. Down below connecting the T to the flex tube was simple as well, with a long screw operated retention band. This system has sealed a once very leaky and drafty 100 year old chimney, making for a very inexpensive solution to what was a health and fire hazard before. Highly recommended.

I was told by a chimney installer to make sure that I got this liner it is the best on the market

Strong construction, loved the quick delivery and response from seller when I reached out to them..
