Abstract
A fire-protection apparatus contains a housing with a passage, and an insert containing a plurality of sections made of a flexible material.
Claims19
A fire-protection apparatus, comprising:
- a hollow housing comprising a passage;
- at least one bracket having at least one opening, configured for receiving a fastener to fasten the apparatus to a wall, floor, or ceiling;
- and
- an insert in or coupled to the hollow housing and comprising:
- a plurality of sections,
- wherein the plurality of sections are tapered and are separated from one another by a plurality of slits arranged in a radial pattern in a 360° arrangement around a hole in the insert in an installed state, and configured to move flexibly to accommodate one or more lines extending through the hole and the passage of the housing, the plurality of sections comprising a fire-resistant material configured to provide an air seal, an acoustic seal, a smoke seal, and/or a fire seal,
- wherein the at least one bracket is configured so that the housing and the insert extend at least in part past the bracket and outside the surface of the wall, floor, or ceiling in the installed state,
- wherein the fire-protection apparatus does not comprise a gasket outside of the hollow housing for sealing a wall penetration,
- wherein the plurality of sections comprises a plurality of elevations and a plurality of valleys, and
- wherein the elevations and the valleys extend along a longitudinal axis from a front to a back of each section, and along a radial axis from an outer portion toward a central portion of each section.
