Sliders from glass doors

Question

Can't find brand name on slider or doors. These get installed at bottom of door where standard wheel based sliders would go. Instead of wheels, they have white cylindrical bearings. Asked several places and noone has seen one like these. Any help is appreciated. Thanks

Many thanks for writing in. I am afraid this old 'tank tread' roller is no longer made. However, we've had people successfully use our 81-279 as a replacement. The adjustment screw sits a little higher than on your old roller but the wheel rides better than the noisy treads. Take a look and let us know what you think.
