Abstract: A corner bracket assembly for use in an associated movable frame assembly is provided. The corner bracket assembly includes a first housing piece having upstanding coupling pins. A second housing piece has receiving pockets for connecting engagement with the coupling pins and defining a cavity therebetween. A roller assembly is received within the cavity. The roller assembly includes a roller housing, a threaded engaging portion defined in the roller housing, and a roller rotatably mounted within the roller housing. A threaded fastener is rotatably mounted between the first and second housing pieces and is in threaded engagement with the roller assembly. A track is defined between the first and second housing pieces and the roller assembly for linearly adjusting a position of the roller assembly in relation to the first and second housing pieces.

Abstract: A corner bracket assembly for use in an associated frame assembly is provided. The corner bracket assembly comprises a body, a first leg and second leg. The first leg extends from the body and is adapted to be connected to a first frame member of the associated frame assembly. The second leg extends from the body in a direction approximately normal to the first leg and is adapted to be connected to a second frame member of the associate frame assembly. The corner bracket assembly further comprises a roller element rotatably mounted within one of at least two axially spaced positions in at least one of the body, the first leg, and the second leg. The roller element protrudes outward a selected distance relative to at least one of the body, the first leg, and the second leg.
