Abstract:
1. A self-adjusting firestopping sleeve apparatus with a flexibly resilient supplemental constriction means for receiving penetrating members such as wires and cables extending therethrough for firestopping therearound comprising: A. a sleeve adapted to be positioned passing through a construction barrier wherein said sleeve defines an access corridor extending longitudinally therethrough for providing access through the construction barrier for positioning penetrating members, said sleeve including: B. a firestopping pad means located within said access corridor and extending at least partially therealong and defining a confinement area extending longitudinally therethrough along said access corridor for receiving and extending around a penetrating member passing through the confinement area and being responsive to exposure to fire conditions thereadjacent to seal therearound to minimize flow of fire, smoke and heat through said access corridor adjacent the penetrating members, said firestopping pad means being generally circular in cross-section with said confinement area being defined extending axially and longitudinally therethrough, said firestopping pad means includes a plurality of belting loops positioned externally thereon and projecting outwardly therefrom; and C. a supplemental constriction means positioned extending around said firestopping pad means for enhancing constriction thereof around the penetrating member extending through said confinement area thereof to facilitate firestopping sealing therearound, said supplemental constriction means comprising a banding member which is longitudinally resiliently flexible, said banding member being positionable extending through said belting loops to facilitate urging of said firestopping pad means inwardly toward said confinement area to enhance firestopping around penetrating members positioned extending axially therethrough.
