Two-piece track system

A fire-rated wall deflection joint comprising:

• an inner track extending in a lengthwise direction of the deflection joint, the inner track comprising a web, a first flange and a second flange, the first and second flanges extending from the web in first direction, wherein each of the first flange and the second flange includes a free end extending in the first direction;
• an outer member comprising intumescent material and extending in a length direction, the outer member further comprising:
• a first peripheral portion;
• a second peripheral portion;
• a central portion;
• a first elongate member coupled with the central portion;
• a second elongate member coupled with the central portion, the first and the second elongate members separated by a distance along a second direction, wherein
• the first direction is perpendicular to the second direction;
• a plurality of studs coupled with the inner track and at least one piece of wallboard attached to the plurality of studs;
• wherein the outer member is disposed over the inner track such that the central portion overlays at least a portion of the web of the inner track, the first peripheral portion overlays the first flange and the second peripheral portion overlays the second flange;
• and
• wherein the inner track and the outer member are coupled to an adjacent structure and the first and second elongate members contact the adjacent structure to seal therewith.
