Measuring 3 inches by 35 feet, this liner is designed for easy DIY installation, backed by a transferable warranty, and meets stringent safety standards in both the USA and Canada. ## Description Your new stainless chimney liner kit will include: Premium Stainless Steel Flexible Chimney Liner (316). The liner is air and water tight sealed. 7 seams with 10 corrugations between each seam. These liners have the very best flexibility and strength combined on today's market. When they heat up they expand, when they cool down they contract, cutting down and fighting against creosote build up. Note: The size given is the inside diameter. Add 1/4" for the outside diameter of the liner. This kit includes a Vertical Appliance Connector where the liner fits into the female side, utilizing the quick connect band. Use the Appliance Connector when you are connecting vertically to the top of a fireplace insert or appliance. A perfect round fit every time thanks to the smooth weld technology. A 13" x 13" Top Plate with a Quick Connect Collar is also included to secure the chimney liner from the top of the chimney. You can trim it to fit with a pair of snips and it's ready for installation. If you need a larger size or different style, please contact us for details. The Quick Connect Flue Cap with mesh screen will keep animals and debris out of the chimney. Fasten down the quick connect clamp to the collar of the Top Plate and you're done! A sharp looking square chimney cap that installs in a snap. Complete do-it-yourself installation instructions (Installing a chimney liner made easy.) If you're at all handy, do this job yourself and save between $1,200 and $2,500. We will support you before and after the sale. Lifetime Warranty and it is transferable if you should ever sell your house. Note: Measure the inside of your flue and inspect for offsets or narrowing sections to be sure it can fit the chimney liner. Highly recommended to contact our Certified Technicians to review the installation before purchasing. Once the flex liner is uncoiled, we cannot accept a return on it. Review: Good quality, priced to market. - The quality of this flue is completely acceptable. The flexible liner is flexible enough to be an easy installation (for someone mechanically inclined at least) and of heavy-enough gauge to inspire confidence when used with a pellet stove. Most importantly I won't be reticent to sweep it firmly and with conviction when the time comes. The other parts of the kit are the chimney cap/rain cover which is plain, basic, and adequate. I had to extend the top capping sheet slightly to cover my opening, but my flue openings are unusually large. The rain cover cover over the opening is perfunctory but again adequate to task for most circumstances. A really dedicated small bird might conceivably be able to nest within during the summer months but it's unlikely. The bottom stove-interface piece was accurately sized and well manufactured, though inserting the recently-cut flexible liner into it was challenging and required quite a lot of cleanup with the grinder. However, this is the price of a close-fitting part and is quite acceptable. Speaking of which, I would consider an angle grinder with cut-off wheel an essential tool for installation as it cut easily through the liner without deforming it or prying the spiral joint apart. Cutting the liner with a hacksaw or powered sawzall blade seems like it could be a recipe for trouble on that front. However, I didn't try them so I may be wrong. As for value for money; these flues are all comically overpriced, based on the cost of materials and packaging. However, as products only occasionally required by the average homeowner, this is the price we pay for doing it ourselves. This was priced slightly better when I bought it than anything else I could find on the market. Review: Perfect - Great product. Works as it should. Perfect length. Very nice kit. ## Features - Complete Do It Yourself installation instructions; We will support you before and after the sale - Rockford Chimney Liner Warranty; The only warranty that is transferable to the next homeowner - UL1777 Listed in the USA and ULCS635 in Canada; Flexible liners are only to be installed inside a masonry chimney - Quick Connect System; Simply tighten the clamps and enjoy your UL listed Rockford liner - Rockford Chimney Liner; Constructed of 316 stainless steel, exceeds all chimney industry standards ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #726,889 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #65 in Fireplace Chimney Caps | | Customer Reviews | 4.6 out of 5 stars 467 Reviews | ## Images ![Rockford Chimney Supply 316 Stainless Steel Flexible Chimney Liner Insert Kit, 3 Inch x 35 Feet - Image 1](https://m.media-amazon.com/images/I/81EajfHg-gL.jpg) ![Rockford Chimney Supply 316 Stainless Steel Flexible Chimney Liner Insert Kit, 3 Inch x 35 Feet - Image 2](https://m.media-amazon.com/images/I/61RIDCgL4XL.jpg) ![Rockford Chimney Supply 316 Stainless Steel Flexible Chimney Liner Insert Kit, 3 Inch x 35 Feet - Image 3](https://m.media-amazon.com/images/I/61LUQt7-NwL.jpg) ![Rockford Chimney Supply 316 Stainless Steel Flexible Chimney Liner Insert Kit, 3 Inch x 35 Feet - Image 4](https://m.media-amazon.com/images/I/51yfHeO6brL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality, priced to market. *by L***R on January 21, 2020* The quality of this flue is completely acceptable.
