ABSTRACT:
A sliding closure panel assembly which is movable along a horizontal track comprises a horizontal bottom member having a plurality of open areas extending laterally therethrough and spaced along the length thereof. A plurality of roller assemblies are mounted in a respective one of the open areas. Each of the roller assemblies includes a hollow frame rotatably carrying a roller and having a pair of opposed side walls and a pair of end walls interconnecting the side walls at their respective opposite ends. Each of the end walls has a notch of U-shaped contour in one edge. The periphery of the roller extends outwardly beyond one edge of each of the opposed side walls remote from the notches in the end walls for rolling engagement with a horizontal flat track surface. When the roller assembly is inverted, the roller is engageable with a horizontal vertical flange or rail with the pair of notches loosely receiving the flange or rail for positively guiding the sliding movement of the closure panel assembly therealong.
