This is an F-tab patio door roller assembly with a 1 inch concave steel ball bearing roller. When the corner screw passes through the F-tab the assembly is then captured by the side stile and bottom rail as the screw draws the two sides together. The housing is 11/16 inch wide and 1-3/16 inch tall with a 7/8 inch dimple width. Used by Lupton and a variety of other sliding patio door manufacturers.
