Seville ClassicsSteel Wire Shelving System Casters, 3" Diameter, Set of 4, Black

We bought several new shelf systems to add to our collection as part of a move. All of the shelves were put in the moving truck and then loaded, but kept under 500 pounds. After driving across country I found that many of the wheels were bent (lots of truck bouncing).Surprisingly, our older Seville shelf systems only had one or two bent wheels, but I had to throw away (and buy these replacements) for eight of the newer wheels.

Super easy to screw in. High quality wheels. Very smooth and quiet. My shelving unit rolls great now.

good quality
