Plastic drawer slide rear mount/backing plate

Thanks for writing in. I am afraid we do not sell drawer sockets with bases that 'plug' into the back of the cabinet like this. Instead, consider the 32-119 Bracket Pair as a substitute. You would need to fasten these to the back of the cabinet with screws, but compare the dimensions, particularly the size of the gap that accepts the track, with your old sockets. If that gap size is comparable, then I think this pair could work as a substitute. See what you think.
