Abstract: The present invention provides an adjustable roller bracket for a retractable door hinge assembly. The adjustable roller bracket device comprises a mounting portion, wherein the mounting portion comprises a horizontal face having a first aperture and an upstanding plate member having a mounting section with a second aperture therein, an adjustable roller support portion, wherein the roller support portion comprises a tubular support member and at least a third aperture and wherein a fastener secures the roller support portion to the mounting section in a predetermined position. The roller support portion is adjusted relative to the hinge assembly accordingly so that the use of different sized hinges are no longer required during the installation of overhead retractable door panels.

Abstract: The present invention provides a double roller device that is adapted for use with overhead, retractable door constructions using a plurality of hingedly connected panels. The device may comprise a hinge roller assembly having a roller mounting plate with a plurality of rollers fixedly attached to a first face of the mounting plate. A U-shaped shaft of the device is secured to at least one hinge by inserting the shaft into the roller stem mounting tube associated with such hinges.
