Rock-Vent Insulated Tee and Tee Cap

The Rock-Vent Insulated Tee and Tee Cap will be located at the base of the chimney in your installation. The Tee can be installed on the interior or the exterior of a structure. The included tee cover is now easier to remove by means of a one nut driver connection; it's easy to remove, yet childproof. Install with a wall support or a tee support assembly. The Standard Tee features a deep bottom reservoir, extending 8.75" below the snout, which means you do not need an extra section of pipe when using a tee support assembly to attach the tee cover. The tee snout length measure 3" in length. No more screws stripping out on the tee cover, making cleaning and inspection a breeze! We offer two steel options for the Insulated Tee: 304L Stainless Steel Inner/430 Stainless Steel Outer or 316L Stainless Steel Inner/430 Stainless Steel Outer.
