Claim 15:
16. A fire-rated head-of-wall assembly that allows dynamic movement, comprising:
a header track coupled to an upper surface, the header track having a web and first and second flanges extending from the web in a same direction away from the upper surface, wherein each of the first and second flanges is substantially planar such that the header track defines an interior space;
a stud coupled to the header track, an upper end of the stud located between the first and second flanges;
a wall board coupled to the stud;
a deflection gap formed between an upper end of the wall board and the upper surface, the deflection gap being variable between a closed position and an open position relative to one another;
a head-of-wall sealing device, the head-of-wall sealing device comprising:
a profile comprising an upper free end and a lower free end;
wherein an interior space of the head-of-wall sealing device is at least partially defined and enclosed by the profile;
a gasket that projects from the profile;
a fire-blocking material disposed within the interior space of the head-of-wall sealing device;
wherein the profile contacts an associated one of the first or second flanges of the header track and cooperates with the header track to surround the fire-blocking material; and
wherein the gasket contacts the upper surface, and the wall board at least partially overlaps the head-of-wall sealing device in the open position and the closed position of the deflection gap.
