The tee has an oval shaped body and is attached to the bottom of a chimney pipe / liner. The horizontal snout of the tee is round and 10" long female and fits into the thimble of your chimney wall. Note: Slight expansion on the end of the tee snout portion makes overall snout diameter 3/8" larger. Watch our video How to Install a Shaped Liner Tee Connection.

Note: Oval chimney liner components are custom made to your specifications and are not refundable. Please contact us if you have any questions.
