Prime-Line D 1988 1-1/2 in Tandem Steel Roller with Ball Bearing for Plain Back (Single Pack)

This steel construction forms the basis of a simple tandem roller assembly, equipped with two 1-1/2 inch concave or grooved steel ball bearing rollers. The hallmark of this design is its stamped steel housing, which boasts adjustability for versatility. Primarily employed in vinyl patio doors, it has been recognized by manufacturers like Keller and others in the industry. Measuring 11/16 inch in width, 1 inch in height, and 3-1/8 inches in length, the housing houses a 1/4-20 threaded mounting hole at its rear end. Notably, a stabilizing tab is strategically placed on the top of the housing to ensure stability during operation.

Designed specifically for sliding doors, this tandem roller assembly incorporates a ball bearing roller that is securely affixed to an adjustable steel frame. Its primary application lies in vinyl patio doors, catering to the requirements of both Keller and a diverse range of metal sliding patio door manufacturers. The combination of a concave roller, plain back configuration, and the adjustable housing makes it a reliable choice for these types of doors.
