Product review (2 stars): The item I received was not usable without a part form the old piece.
The support uses an expansion fitting with a pin you drive into the expansion fitting to secure  it to the inside of the refrigerator wall. When I attempted to install the replacement part, the extra material  on the pin (see picture)  made it impossible to drive into the expansion fitting, and almost broke the new support. Thankfully, I salvaged the pin from the old failed support, and used that to secure it to the wall.

Some people might lose their old pin inside the wall of the refrigerator, so I would recommend a different slightly more expensive version with better quality control.

Update: Added a picture of the pin that keeps this piece from functioning at all. The pin should be smooth from the shaft to the point, but this one had a bunch of chaff and extra material that would require nipping or grinding/shaving off to use. It isn't just a little piece, either, but thick, as though it were cast that way.
