Raccoon Screens
This heavy-duty animal control screen is built to prevent access to the chimney from even the most bothersome animal pests such as raccoons or opossums. Its tamper-proof bolt-on attachment method makes it impossible for pests to remove and gain access.
Adapter Plate
The plate is made from 18ga 304 stainless steel and is designed to adapt our National Chimney skirt style Co-Linear cap to a flat surface. If you need a Co-Linear cap but you do not have a ceramic flue tile to connect it to, this plate is the answer. The plate will sit nicely onto a flat crown surface or a flat top plate. The plate has a 2" high collar that slips inside the Co-Linear cap. The angle flanges on the plate have slotted holes that line-up with the cone point screws on the Co-Linear cap for easy connection. The plate has a 2" border on all four sides for either mortaring into the crown or for screwing down to a top plate.
