18” x 18” Flat Bottom Plate with an oval collar to accept the oval chimney liner at the bottom. The 18” x 18” flat plate can be trimmed down with a pair of good tin snips. With this oval quick connect bottom plate all you need to do is insert the liner inside the bottom plate and tighten down the screw on the outside of the collar, and your liner is clamped in place at the bottom of your chimney flue. We will match the oval bottom plate to the oval liner selected in step one.
