Drawer Track Backplate

A quick learner from Phoenix says:
I am searching for what I believe to be a drawer track back plate. The one in the picture was manufactured by Ronthor NYC. The square is 15/16" to the exterior edge of the square. I suspect the top which screws or staples into the back of the cabinet is another inch but as you can see the plastic broke. Let me know if you can help me identify this part and if you have them. Thanks!

Hi there!

Thank you for reaching out to us. We don't sell this exact socket, I'm afraid. Our 32-001 is similar in design and may be worth considering though. This socket is 11/16" deep and the inside measures 7/8" x 7/8". Take a look at the specifications and see how they compare with yours.
