Product review (5 stars): Works Perfectly!
We have a LG LFX28977ST that had a cracked tray.  I tried gluing it several times but it kept getting worse.  I bought this and it fits perfectly and holds my gallon milk jugs with no problem.

My only negative comment is my original had a genuine simulated aluminum plastic edge and this one is clear across the top.  It's hard to tell from the picture.  Guess they changed them on the newer models.  If you're OCD, then you might want to keep looking or order enough to replace all the bins.  I'm just glad I have a sturdy shelf again.
