drawer duides
Thanks for reaching out to us. This looks like it may be an old Ronthor track that isn't made anymore. The best option in our inventory is the 32-053 drawer track kit. Take a look and see if you think you can adapt this to your drawer.
No, this is the best and only match we have for your hardware but the track can be cut to the desired size. Starting at the 1:02 mark in the video above, you can see how we cut it down in cases like this.
The two corner guides go at the front of the cabinet on the cross member. They are attached at the corners of the cross member so the bottom sides of the drawer can ride on them. I hope this helps.
