Abstract: An apparatus for sealing an opening, or the like, in a fire partition through which an existing combustible conduit extends includes a first enclosure capable of being fastened to the fire partition on one side of the conduit opening and having a first recess therein. A second non-combustible enclosure capable of being fastened to the fire partition on a side of the conduit opening opposite the first enclosure, has a second recess therein and is hingedly connected to the first non-combustible enclosure. The first and second enclosures lie in a common plane and are operable, through the use of the hinged connection, to be spread apart for installation over the existing combustible conduit and can be closed together such that a recess-formed opening is defined about the conduit by the first and second recesses.

Abstract: A fire stopping apparatus includes a metal casing having two side walls with co-extensive openings and an annular outer wall extending between the side walls outwardly from the openings, forming an inwardly open, annular channel. The casing has mounts for connecting the apparatus to a building structure. There is an intumescent material within the channel. A resilient gasket extends from the casing and has an annular inner wall extending inwardly beyond the intumescent material.

Abstract: A gasket wrapping apparatus including a pair of plate members positioned on a crank member rotatably mounted on a support member. The crank member and one of the plate members include slots located therein which are aligned to receive the end of a strip of material positioned between the plate members. Rotation of the crank member coils the strip of material around a hub portion of one of the plate members. Removing the plate member with the hub portion from the crank member enables an adhesive member to be applied to the mounted coiled material facilitating the removal and storage of the coiled material.
