Product review (5 stars): Great Fix for Falling Freezer Shelves
After researching online about why my freezer shelves were falling off the shelf guides, I discovered that it is a common problem for the inside walls in GE fridge/freezer side-by-sides to warp in to the center over time.  The freezer shelf guides/holders are pulled along with that wall until they are just out of reach of the freezer shelves.  So I bought 4 of these spacers for each shelf and snapped them onto the sides of the shelves to make the shelves wide enough to sit on the shelf holders again.  Cheap, functional solution.
