Product review (3 stars): Yes these will work after you do some DIY to them.
Previous posters are correct in that if you have one track or rail break, you can swap and rotate them around with the other non broken one. We did this last year and saved us money initially. But because the design is awful, these rails/tracks are only as good as the plastic they are made from and the weight load they are forced to carry. This will break at some time because we all cram a lot of stuff in the deli drawer, so if you are ordering them, I'd order an extra one just to have stored away and after you rotate the first time. Once you rotate them after they break, you can't rotate them anymore. I gave a 3 star review because the parts are fine for what they are but the design of the whole thing needs to go back to the drawing board. Also, as other people have pointed out, these don't fit properly out of the bag. Thank you to the previous users who said they used a Dremel to shear down the 3 circle/knob things that prevent the tracks from sliding into place. Once I used my Dremel, it worked fine. You can risk trying to bang them into place but you may break the plastic doing so.
