3 1/2" Heavy Duty Rubber Donut Bumper for Carts and Mobile Shelving Units

Useful because it can be used in a variety of helpful ways. In our case, it was useful to protect our cabinets from the shelving. You can use it for more than just wall protection!

These work wonderfully in keeping my mobile shelving carts from banging against each other. You kind of have to squeeze the poles in the holes, but I like that because you can put them anywhere up and down the posts, unlike ones that are too big for the posts and have to be supported by a shelf or the wheels. Very happy I invested in these.

We've purchased a ton of these... and after a recent upgrade of shelving systems, these were downgraded. BUT not for low quality, it was simply the smarter decision in a super tight cooler where every inch counts. If you have the space (whether in a cooler, utility room, or storage, these are awesome hands down). But you really need to figure out your space situation if (like us, and many others) space is an issue where every inch counts. I've managed to add just the right amount of space by removing these in my cooler, but am using these in my utility room where I have more space. The are great additions to all your shelving systems.
