A fire-rated angle piece and wall assemblies or other assemblies that incorporate the fire-rated angle piece, in which the angle piece includes an intumescent or other fire-resistant material strip. The angle can be attached adjacent to a corner of a framing member, such as metal tracks, headers, header tracks, sill plates, bottom tracks, metal studs, wood studs or wall partitions, and placed between the framing member and a wall board member at a perimeter of a wall assembly to create a fire block arrangement.

1. A fire-rated assembly for a linear wall gap, comprising: a track that has a web, a first flange and a second flange, wherein the web is substantially planar and has a first side edge and a second side edge, the first flange and the second flange extend in the same direction from the first and sec
1. A fire-rated assembly for a linear wall gap, comprising: a track that has a web, a first flange and a second flange, wherein the web is substantially planar and has a first side edge and a second side edge, the first flange and the second flange extend in the same direction from the first and second side edges, respectively, wherein each of the first and second flanges is substantially planar such that the track defines a substantially U-shaped cross section;an angle that has a first flange and a second flange, wherein each of the first flange and the second flange is substantially planar such that the angle defines a substantially L-shaped cross section, each of the first and second flanges has a free end opposite a corner of the angle;a heat-expandable intumescent strip attached to the angle and extending lengthwise along an outer surface of the second flange, the intumescent strip comprising a portion that extends past an outer surface of the first flange of the angle;wherein the first flange of the angle is positioned between the web of the track and an overhead structure with the second flange of the angle being positioned adjacent one of the first or second flanges of the track with at least a portion of the second flange contacting the one of the first or second flanges of the track. 2. The assembly of claim 1, wherein the free end of the second flange defines a kick-out portion that extends in a direction opposite the first flange. 3. The assembly of claim 2, wherein the free end of the first flange defines a locking hem configured to inhibit or prevent removal of the angle from an installed position between the track and the overhead structure. 4. The assembly of claim 1, wherein the free end of the first flange defines a locking hem configured to inhibit or prevent removal of the angle from an installed position between the track and the overhead structure. 5. The assembly of claim 1, wherein an angle defined between the first flange and the second flange of the angle is less than 90 degrees such that a gap is created between an upper end of the second flange of the angle and an upper end of the one of the first and second flanges of the track. 6. The assembly of claim 5, wherein the angle is approximately 87 degrees. 7. The assembly of claim 1, wherein the first flange of the angle defines a plurality of V-shaped cut-outs extending from the free edge toward the corner. 8. The assembly of claim 1, wherein the intumescent strip extends along and is attached to a portion of the first flange of the angle such than the portion contacts the overhead structure when the fire-rated assembly is assembled to the overhead structure. 9. The assembly of claim 8, wherein the intumescent strip defines a total length in a cross-sectional direction, wherein a portion of the total length located on the second flange is at least three times greater than a portion of the total length on the first flange. 10. The assembly of claim 8, wherein the intumescent strip covers a substantial entirety of the outer surface of the second flange. 11. The assembly of claim 1, wherein the one of the first and second flange of the track is longer than the second flanges of the angle. 12. The assembly of claim 11, wherein one of the first and second flange of the track is at least about twice as long as the second flange of the angle. 13. The assembly of claim 1, further comprising a plurality of slots on the first and second flanges of the track, wherein the slots extend in a direction perpendicular to a length of the first track. 14. The assembly of claim 1, wherein the track is a footer or header track. 15. The assembly of claim 1, wherein the track is a stud framing member made from wood or metal. 16. The assembly of claim 1, further comprising a plurality of studs and a wall board, wherein an upper end of each of the studs is received within and secured to the track and the wall board is secured to the plurality of studs, wherein the second flange of the angle is positioned between the wall board and the one of the first and second flanges of the track. 17. A method of assembling a fire-rated wall joint, comprising: securing a header track to a ceiling;positioning a horizontal leg of an elongated, generally L-shaped fire-rated angle piece between the header track and the ceiling such that at least a portion of an intumescent material strip located on a vertical leg of the angle piece faces away from the header track;positioning upper ends of a plurality of studs into the header track;securing at least one wall board member to the plurality of studs such that the vertical leg of the angle piece is positioned between the at least one wall board member and the header track. 18. The method of claim 17, wherein the positioning of the horizontal leg between the header track and the ceiling is done after the securing of the header track to the ceiling.
