Rockford Chimney Supply 316 Stainless Steel Flexible Chimney Liner Insert Kit, 6 Inch x 30 Feet

very affordable and fast shippping

Worked perfectly. Slid it down my 7” square flue. I had to tie a rope onto the end so I could push and pull to get it the whole way down. Stood up to the abuse.

I loved the quality of the liner and I also purchased the insulation kit. My only thing that kept this from 5 starts is the chimney cap. When I slid it over the liner and silicone it to the top of the Terra cotta it wouldn't sit flat. I had to put a pile of bricks on it and then strap them down to hold it in place until the silicone cured. That's not a very solid connection. I decided I needed to find a way to keep it in place when high winds come. I cut off the bottom of the old chimney cap and clamped it down on top. It's been a few days and we had 35mph winds and it seems to be working so far. In my opinion the cap needs a better design. Or scrap this and send a better one in the kit. Something that can be secured by means other than just a bead of silicone.
