Product review (2 stars): Doesn't fit applicable refrigerator.
This track did not fit my Whirlpool refrigerator even though the ordering data provided by amazon said it would fit.  The problem is with the three mounting tabs on this track that were thicker than those on the original track which prevents the track from being inserted into the three mounting slots on metal bracket which supports the glass shelf.
I had to use a box cutter to trim the plastic tabs so they could fit into the supporting metal bracket. No problems after that modification.
