About this 3D model
These are replacements for the part of the rail system on a drawer that supports the back end of the rail. I assume that these can be used on a very large majority of drawers as they all use this common rail system. The brackets are made to accomodate a 22-10mm rail and the tollerences are built in so all will fit well. The screw holes are designed to accomodate 2mm screws and there are a couple of different mounting locations to suit your needs.
