Product review (5 stars): Fits with original shelf support
I bought this to replace the same part that had cracked and broken on my LG refrigerator, model #LFC20760S. It fits perfectly and works the same.  I did NOT buy the shelf support, despite reading on other websites that it was required for this item since the original wouldn't fit.  It didn't make sense, since if this item would have to fit my refrigerator then it would also have to fit with the existing shelf support.  I was right, and both fit together and support the crisper drawers just fine.  The only problem was in the packaging.  The cover arrived in a huge LG box that was barely taped shut.  The cover was barely wrapped in flimsy plastic and there was no other packing material in the box for protection.  Luckily, the cover was not damaged or broken, but that seems to be in spite of the packaging and not because of it.
