Abstract
Track guided doors, such as upward acting multipanel garage doors are provided with roller guide member support brackets on opposite side edges of the panels for supporting guide rollers disposed in the opposed guide tracks. The support brackets include bearing bores formed by bore walls of the support brackets for supporting elongated stem or shaft portions of the roller guide members. The roller guide members may include leaf springs mounted in grooves on the guide member shaft portions or the support bracket may include elastically deflectable clips mounted thereon, the leaf springs and clips providing resilient members for engagement with the stem parts, respectively, to bias them into engagement with the bore walls of the support brackets to minimize noise generated by the guide members during movement of the door.
