I believe you might be referring to old old 'tank tread' rollers, which are no longer made. However, we've had people successfully use the 81-279 as a replacement. Please note that the adjustment screw sits a little higher than on your old roller, but the wheel runs nicer than the noisy treads. Let me know what you think.
