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 defining an adjustment slot extending longitudinally along said access corridor which is in fluid flow communication therewith, said sleeve including: B. a first firestopping pad means located within said access corridor and extending at least partially therealong; C. a second firestopping pad means located within said access corridor and extending at least partially along said access corridor to define a confinement area between said first firestopping pad means and said second firestopping pad means within said access corridor for sealing around a penetrating member passing through the confinement area in response to exposure to heat, at least one of said firestopping pads having at least a portion thereof that is movable toward the other of said firestopping pads to facilitating firestop sealing therebetween; and D. a supplemental constriction means extending around first firestopping pad means and said second firestopping pad means for biasing thereof together toward a penetrating member extending through said confinement area to facilitate firestopping sealing therearound, said supplemental constriction means comprising a banding member which is flexibly resilient and is positioned encircling said first firestopping pad means and said second firestopping pad means for urging same together, said banding member including an adjustment portion positioned extending outwardly through said adjustment slot to facilitate adjusting of the magnitude of biasing exerted between said first firestopping pad means and said second firestopping pad means by varying the positioning of said adjustment portion within said adjustment slot.
