ABSTRACT:
A track assembly for a bi-fold door comprises a guide track having an elongated flat base, a pair of sides, and a pivot bracket. The outer edge of each side of the track is inwardly directed toward the base and defines a channel therein. A pair of runners extending from the pivot bracket provides means for reinforcing a portion of the guide track and reduces track vulnerability to deformation caused by lateral forces.
