  • quick connect rain cap Square Quick Connect Flue Cap with mesh screen. Fasten down the quick connect clamp to the collar of the Top Plate and you're done! A sharp looking cap that installs in a snap. The chimney cap reduces the risk of animals, debris, and weather entering the home.

It's your choice; simply select your preference at the top of this listing.
  • Complete 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.

  • Stainless Steel Retractable Mesh - Keeps the insulation from being damaged during install and holds the insulation in place over time.
