Looking for replacement

Thanks for posting. We cannot offer an exact replacement for the track, roller, and socket you have pictured, unfortunately. We sold the roller guide at one time, but it was discontinued back around 2015 and there was no alternative was made, that we know of. 

Our 32-053 Drawer Track Kit may work as a replacement. You'll need to carefully compare the measurements from the socket and take a look at the other details of the part to confirm if it would be the right fit.
