A top guide for mounting an upper portion of a door panel assembly with respect to a track providing vertically disposed opposing parallel track surface includes an integrally molded plastic mounting structure. The mounting structure includes connectin g portions constructed and arranged to enable the mounting structure to be connected to a door panel assembly. The mounting structure further comprises first and second roller mounting portions. First and second rollers are mounted for rotation on the first and second roller mounting portions, respectively. The first roller mounting portion is formed on a portion of the integrally molded plastic mounting structure which is resiliently biased to enable the first roller mounted thereon to be in biased engagement with one of the track surfaces when the top guide is mounted with respect to the track. The resiliently biased porti on of the integrally molded plastic mounting structure is resiliently biased from the resiliency of the plastic material from which the mounting structure is molded. |
