Abstract: A roller bracket apparatus includes a roller assembly which includes a carriage portion and a link portion projecting from the carriage portion. A push/pull assembly is provided, and a pivot assembly is connected between the link portion of the roller assembly and the push/pull assembly. The carriage portion includes a wheel-support portion and a plurality of axle/wheel assemblies supported by the wheel-support portion. Each of the axle/wheel assemblies includes an axle and a roller wheel connected to the axle. The link portion extends from the carriage portion at an acute angle with respect to a plane common to the top surface of the carriage portion. In an alternatively preferred embodiment of the invention, the push/pull assembly includes a first side portion connected to the article being moved (e.g. an overhead door panel) and an integrated gusset plate portion orthogonally connected between the first side portion and the pivot assembly.
