1-1/4 in., Nylon Ball Bearing, Sliding Door Roller Set (2-pack)

This is a combination of a 1-1/4 in. diameter nylon concave ball bearing roller that is 5/16 in. thick with a 1/4 in. axle hole and a combination of five different axle choices. Depending on the situation, you can choose to rivet the roller into place or use a roll pin, drive pin, binder post and screw or bolt and nut. Regardless of how you need to install the new roller into your existing roller housing, in most cases, one of the five choices will work.
