A fire-rated angle piece and wall assemblies or other assemblies that incorporate the fire-rated angle piece, in which the angle piece can include 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. A fire spray material can be applied over a portion of the angle piece.

A fire-rated wall joint product, comprising: an elongated, generally L-shaped angle piece comprising a first flange, a second flange oriented at a first angle relative to the first flange, the second flange having a width greater than the first flange, and a flap oriented at a second angle to the first flange and extending toward the second flange, the second flange and the flap each having a free edge, the first flange and the second flange connected to each other along an edge thereby defining a first corner, the first flange and the flap connected to one another along an edge thereby defining a second corner, the first flange and the flap having planar portions, the first and second flanges and the flap being formed from a single piece of material; andan intumescent material strip applied to an exterior surface of the first flange, wherein a width of the intumescent material strip is equal to or less than about one-half a width of the first flange. 3. The fire-rated wall joint product of claim 2, further comprising a second intumescent material applied to an exterior surface of the second flange. 4. The fire-rated wall joint product of claim 2, wherein the second flange further comprises a kickout portion such that a lower portion of the second flange is parallel to the upper portion of the second flange. 5. The fire-rated wall joint product of claim 2, wherein the flap further comprises a second intumescent strip applied to an interior surface of the flap. 6. A fire-rated wall joint product, comprising: an elongated, generally L-shaped angle piece comprising a first flange, a second flange oriented at a first angle relative to the first flange, and a flap oriented at a second angle to the first flange, the second flange and the flap each having a free edge, the first flange and the second flange connected to each other along an edge thereby defining a first corner, the first flange and the flap connected to one another along an edge thereby defining a second corner, the first flange and the flap having planar portions, the first and second flanges and the flap being formed from a single piece of material; andan intumescent material strip applied to an exterior surface of the first flange, wherein a width of the intumescent material strip is equal to or less than about one-half a width of the first flange, wherein the flap further comprises a first section and a second section oriented at an angle relative to the first section, the first section and the second section being connected to one another along an edge defining a corner, the second section substantially parallel to the first flange. 7. The fire-rated wall joint product of claim 2, wherein the intumescent material strip wraps the first corner between the first flange and the second flange. 8. A fire-rated wall joint product, comprising: an elongated piece comprising a strap having a free edge and a hem having an outwardly curved portion that folds over and overlaps a lower portion of the strap, the strap and the hem being formed from a single piece of material; andan intumescent material strip applied to an exterior surface of the strap and extending beyond the free edge of the strap. 9. A fire-rated wall joint product, comprising: an elongated piece comprising a strap having a free edge and a hem having an outwardly curved portion, the strap and the hem being formed from a single piece of material; andan intumescent material strip applied to an exterior surface of the strap and extending beyond the free edge of the strap,wherein the strap further comprises a kickout portion such that a lower portion of the strap is parallel to the upper portion of the strap. 10. The fire-rated wall joint product of claim 9, wherein the strap has a two-ply section having a first layer and a second layer such that the free edge of the strap is adjacent the kickout portion of the strap, the two-ply section forming a gap between the first layer and the second layer. 11. The fire-rated wall joint product of claim 10, wherein an intumescent material is applied within the gap. 12.
