I had no idea how hard it would be to find simple European style drawer slides to replace the ones that broke in my dresser. I ordered these because they looked the part and were cheap, but they were perfect. 3 of the 4 screw holes were in the same places as the old rails I was replacing and it was the best I could find. Once installed, the drawers would slide in and out much more smoothly than the old ones did when they were new. They seem to be more durable than the ones that came with my dresser. Note that they do not have ball bearings and are not fancy rails. They're just basic drawer slides, but they're good at that (at least for now). I actually bought two more to replace the other drawers in the dresser because they work so much better.
