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 surfac

The present invention is directed toward a track assembly comprising 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. The system may further comprise a strap or series of engaging surfaces on the inner and outer tracks that generally restrain the inner track relative to the outer track.

What is claimed is: 1. A two-piece header track system for use in a stud wall assembly, the stud wall assembly extending in a vertical direction between a lower horizontal support element and an upper horizontal support element, upper ends of a plurality of studs being received by the two-piece hea

What is claimed is: 1. A two-piece header track system for use in a stud wall assembly, the stud wall assembly extending in a vertical direction between a lower horizontal support element and an upper horizontal support element, upper ends of a plurality of studs being received by the two-piece header track system, the two-piece header track system comprising: an elongate inner track comprising a first web and two first flanges, the inner track configured to receive the wall studs therein, the inner track comprising a first width and a second width greater than the first width; an elongate outer track comprising a second web and two second flanges, the outer track configured to receive the inner track in a nested arrangement therewithin so as to generally restrain side-to-side movement of the inner track but permit relative movement of the inner track along the along the length of the outer track, the outer track having an overall width substantially equal to or less than the second width of the inner track; further comprising a removable setting strap wrapped at least partially around the tracks for restraining the tracks from being pulled apart in a generally vertical direction when the tracks are in a nested arrangement. 2. The two-piece header track system of claim 1, wherein the first and second flanges comprise a plurality of angled surfaces working in conjunction to restrain the tracks from being pulled apart in a generally vertical direction when the tracks are in a nested arrangement. 3. The two-piece header track system of claim 1, wherein at least one first flange is positioned substantially flush with a corresponding second flange when the tracks are in a nested arrangement. 4. The two-piece header track system of claim 1 further comprising intumescent material applied along at least a portion of the length of the outer track. 5. The two-piece header track system of claim 1, further comprising at least one opening in the first web extending substantially entirely across the first web. 6. The two-piece header track system of claim 1, wherein the inner track comprises an upper portion nested within the outer track and a lower portion for receiving the upper ends of the studs. 7. The two-piece header track system of claim 1, wherein each of the inner and outer tracks is roll-formed from a single piece of material. 8. A two-piece header track system for use in a stud wall assembly, the stud wall assembly extending in a vertical direction between a lower horizontal support element and an upper horizontal support element, upper ends of a plurality of studs being received by the two-piece header track system, the two-piece header track system comprising: an inner track comprising: an inner elongate top web portion; a first inner elongate side flange portion; a second inner elongate side flange portion, the first and second inner elongate side flange portions extending downward from opposite sides of the inner elongate top web portion, the inner elongate top web portion and first and second inner elongate side flange portions defining a space for receiving the upper ends of the studs, the width of the inner top web portion being less than the greatest width between the first and second inner elongate side flange portions; an outer track comprising: an outer elongate top web portion; a first outer elongate side flange portion; a second outer elongate side flange portion; wherein the inner track is at least partially nested in the outer track such that outer surfaces of the first and second inner elongate side flange portions are substantially aligned with outer surfaces of the first and second outer elongate side flange portions; wherein the inner track comprises an upper portion nested within the outer track and a lower portion for receiving the upper ends of the studs; wherein the upper portion comprises a first surface and two second surfaces extending from opposite ends of the first surface inwardly towards one another at an acute angle relative to the first surface. 9. The two-piece header track system of claim 8, wherein the first and second inner and outer elongate side flange portions comprise a plurality of angled surfaces working in conjunction to restrain the inner and outer tracks from being pulled apart in a generally vertical direction when the tracks are in a nested arrangement. 10. The two-piece header track system of claim 8, wherein the first and second outer elongate side flange portions of the outer track comprise ends which are curved inwardly towards one another so as to cooperate with the upper portion of the inner track to restrain the inner and outer tracks from being pulled apart in a generally vertical direction when the tracks are in a nested arrangement. 11. The two-piece header track system of claim 10, further comprising intumescent material applied along at least a portion of the length of the outer track. 12. A two-piece header track system for use in a stud wall assembly, the stud wall assembly extending in a vertical direction between a lower horizontal support element and an upper horizontal support element, upper ends of a plurality of studs being received by the two-piece header track system, the two-piece header track system comprising: an outer track comprising an elongate top web portion and first and second elongate side flange portions extending from opposite sides of the top web portion, the first and second elongate side flange portions each having a bent profile such that the first and second elongate side flange portions generally define inwardly angled surfaces; an inner track comprising an elongate top web portion nested within the outer track, the inner track further comprising first and second elongate side flange portions extending from opposite sides of the top web portion, the first and second elongate side flange portions each having a bent profile such that the first and second elongate side flange portions generally define inwardly angled surfaces; wherein the bent profiles of the first and second elongate side flange portions of the outer and inner tracks cooperate to inhibit the inner track from moving relative to the outer track in a side-to-side direction, but permit relative movement of the inner track along the length of the outer track; wherein the first and second elongate side flange portions comprise a plurality of angled surfaces working in conjunction to restrain the inner and outer tracks from being pulled apart in a generally vertical direction when the tracks are in a nested arrangement; wherein the upper portion comprises a first, horizontal surface and two second surfaces extending from opposite ends of the first surface inwardly towards one another at an acute angle relative to the first surface. 13. The two-piece header track system of claim 12, wherein the inner track comprises an upper portion nested within the outer track and a lower portion for receiving the upper ends of the studs. 14. The two-piece header track system of claim 12, wherein each of the inner and outer tracks is roll-formed from a single piece of material.
