Product review (5 stars): It fits my Frigidaire model FFTR2021TW and works great
As soon as my new refrigerator was delivered I followed the advice of an earlier reviewer and bought this item to replace the middle door shelf rack. The rack the middle door shelf came with stuck out too far and let small jars fall through between the shelf and rack, but this one prevents that problem. Also, I think it's less likely to get broken since it doesn't stick out as far.

As others have mentioned, ignore the size that is listed on the Amazon page for this item. It is not that long.
