Abstract: A firestopping apparatus including a housing defined by first and second housing members. Each housing member includes a width direction wall panel and a height direction wall panel. The width direction wall panel of the first housing member is configured to connect with the height direction wall panel of the second housing member and the width direction wall panel of the second housing member is configured to connect with the height direction wall panel of the first housing member to define an assembled housing with a through passage. Intumescent material is positioned along an inner surface of each wall panel. A compressible foam is positioned within the intumescent material and substantially closes off the through passage.

Abstract: A firestopping apparatus including a housing having a wall surface extending between opposed front and rear panels with an inner chamber defined therein. The front panel defines a front opening therethrough and the rear panel defines a rear opening therethrough. The housing includes first and second housing members which are moveable relative to one another between an assembled condition wherein the first and second housing members are interconnected and the wall surface is substantially continuous about the internal chamber, and an open condition wherein at least a portion of the first and second housing members are spaced from one another such that at least a portion of the wall surface is non-contiguous to define an opening into the internal chamber. An intumescent material is positioned within the internal chamber.
