Abstract
A fire-rated receiver channel includes at least one intumescent or other fire-resistant material strip. The receiver channel can nest with a framing member, such as metal tracks, headers, header tracks, sill plates, bottom tracks, metal studs, wood studs or wall partitions, and placed at a perimeter of a wall assembly to create a fire block arrangement. In other arrangements, a track assembly includes two nested tracks, an inner track and outer track. The assembly is designed so that the outside width of the outer track is equal to or less than the outside width of the inner track to present a substantially flush external surface for attachment of exterior sheathing elements when the assembly is used in an external wall.
Claims6
A fire-rated header track cap for sealing a horizontal wall gap, the horizontal wall gap defined by a ceiling member, a U-shaped header track, and at least one wallboard, the fire-rated header track cap comprising:
- a U-shaped member configured to extend in a lengthwise direction of the header track, the U-shaped member having a channel defined by a middle portion, a first side portion and a second side portion, the first and second side portions extending substantially perpendicularly from opposing sides of the middle portion;
- and
- fire-retardant material attached to and extending lengthwise along the U-shaped member, the fire-retardant material substantially covering an entire surface of at least one of the first and second side portions;
- wherein the U-shaped member is configured to be positioned over the U-shaped header track such that the fire-retardant material is positioned between the ceiling member and a web portion of the U-shaped header track and the fire-retardant material is positioned between a flange portion of the U-shaped header track and the at least one wallboard.
