Product review (5 stars): Works Great in our Side by Side Fridge's Freezer
I actually use these in the freezer section of our (full-sized) side by side refrigerator to keep heavy frozen things from falling off the (poorly designed) freezer shelving and onto the tops of our feet/toes. I've had these in the freezer for almost 2 weeks so far, and have not had any trouble with these slipping due to freezer moisture yet, which I was initially concerned about prior to using these. I have them no more than 1 inch above each shelf, just enough to give us a bit of a ledge, but still enough room to reach in and pull out what we need.

The sizing of these is accurate, and the spring in these is very strong while the outer portion is very sturdy when in place and finished with nice, thick end caps. I am so glad I took a chance on these, they are well-made and have been such a helper in the freezer. Thanks for reading!
