This Firestop for Straight-Up Chimneys is one of the best, since it's manufactured by Majestic. Its heavy-duty design is made to be used with a triple-wall flue that is 8" in diameter. This firestop is also designed to be used only with flues that are straight up and down. A firestop is required at each floor level and/or attic of a multi-story chimney, and this is a great option if you have a triple-wall venting system.
