Abstract
Fire rated cleanout covers that restore and maintain a fire-rating of a constructed wall assembly. The fire rated cleanout covers are attached directly to cleanout tees to eliminate the need to secure a separate base component to a wall. Intumescent material is pre-incorporated with the fire rated cleanout covers prior to installation of the fire rated cleanout covers. As such, the intumescent material is carried with the fire rated cleanout cover when the fire rated cleanout cover is in use. The fire rated cleanout covers allow an installer to reuse the fire rated cleanout covers after maintenance or cleaning without reapplying the intumescent material to restore the fire rating of the wall.
