Claim 10

A device for enabling cables to be pulled therethrough and through a concrete slab floor in which the device is adapted to be mounted, for connection of the cables from under the floor, to an outlet therefor in a service fitting for the cables, to which the device is adapted to be connected, to activate the service fitting, which device is adapted to be inserted into a hole to be formed through the floor after setting of the concrete in the floor, and to be engagable with the wall of the hole in the floor, and further adapted to prevent heat transmission through the device or through the hole to be formed in the floor, so as to restore the fire rating of the floor with the hole formed therein to substantially the fire rating of the floor without the hole formed therein, to enable the device to be fire-rated, comprising: (a) an elongated hollow housing, generally tubular shaped, the outside diameter of which is less than the diameter of the hole to be formed through the floor, the hollow portion of which is adapted to enable the cables to be pulled therethrough, which housing further includes first and second opposed ends, and first and second opposed end sections; (b) first hollow means connected to the first end of the hollow housing for preventing transmission of heat through the device or through the hole to be formed in the floor, so as to restore the fire rating of the floor with the hole formed therein to substantially the fire rating of the floor without the hole formed therein, adapted to enable the cables to be pulled therethrough; (c) means for connecting the first hollow means to the first end of the housing; (d) means for extending the length of the housing beyond the first end of the housing, adapted to be connectable to the service fitting, including means for enabling the housing means to be connected to the service fitting; and (e) means for engaging the wall of the hole to be formed through the floor, adapted to be connectable to the extending means and engagable by the connection enabling means so as to be movable generally radially outwardly into engagement with the wall of the hole to be formed in the floor.

Claim 11
