Abstract
Abstract A canted wheel carrier for supporting operable wall panels from upper and/or lower supporting surfaces to enable multi-directional movement of the panels and facilitate negotiation of angle turns and intersections without switches or curves in the supporting surfaces with a minimum of frictional resistance thereby reducing the force which must be applied to the panels to move them to a desired location and reducing frictional wear. The invention includes a top or bottom canted wheel carrier with or without a guide member or with a single or multiple canted wheels which engage a top or bottom supporting surface.
