Abstract
A fire stop system with a pass through device is installed in a structural opening. The fire stop system includes a split pipe, a foam wall gasket and an annulus plate. The split pipe includes a first end and a second end. The first end and the second end have an intumescent material installed thereon to seal the split pipe when the split pipe is exposed to elevated temperatures. The foam wall gasket is installed around the split pipe adjacent the structural opening. The foam wall gasket forms a contour to the structural opening blocking air flow between the split pipe and the opening. The annulus plate covers the foam wall gasket and is installed around the split pipe at the structural opening.
