Abstract: An adjustable roller assembly for sliding doors including a housing adapted to be snap-fit into a recess provided in the upper or lower surface of a door frame, the housing defining a cavity which is open at the lower end. A roller carrier is mounted in the housing cavity and is vertically adjustable with respect to the housing. The lower end of the roller carrier defines circular flanges in which is rotatably mounted a roller having an integral hub. A camming arrangement associated with the roller carrier is accessible for adjustment from the side of the door frame and is operable to adjust the vertical position of the roller carrier and roller to adjust the slack between the door and the track upon which the roller is adapted to ride.

Abstract: A square butt hollow door frame including upper and lower rail members, and a pair of stile members wherein the inner walls of the stile members are provided at each end with a recess defining inwardly laterally extending flanges adapted to be received in corresponding slots defined through each end of the upper and lower rail members, such that when the respective flanges are received in the respective slots, a locking mechanism is positioned, thereby securing the side members and rail members together to form a door frame.

Abstract: A metal tine assembly interchangeable with plastic tines on a transverse tubular bat having a teardrop cross-sectional configuration.
