Abstract
Presealed System device for walls, floors and roofs. The Presealed System device forms pre-selected openings in floors and walls and roofs in buildings and/or houses and/or during remodeling projects for allowing plumbing pipes and/or electrical conduits to pass therethrough. The devices include stacked or side by side PVC type sleeves with an inwardly protruding portion of a resilient member such as a t cross-sectional shaped washer separating the sleeves from one another. The resilient member also includes a rearwardly extending portion which extends into the walls and floors that can have ridges thereon, and additional portions which are adjacent to exterior sides of the sleeves. Pipes and conduits placed into the openings through the devices are sealed by the inwardly protruding portions of the resilient members and the seal is maintained during expansion and contraction of the boundary layer that occurs during daytime and nighttime temperature changes and heating and cooling conditions. A fire stop can be additionally added onto one exterior end of the sleeves to help prevent fire from spreading through the pre-formed opening between the boundary. Methods of installing the device prior to pouring the floor and/or forming the wall allow for caps to be placed on exterior open end(s) of at least one of the sleeves, where the cap(s) is removed prior to installing the plumbing pipe and/or electrical conduit through the device.
