Screwed these onto my shelving poles in about ten minutes flat, and the locking mechanism actually holds firm on my garage floor. The polyurethane rolls smooth over uneven concrete without that cheap plastic rattle. Solid upgrade for the price.

I was worried the polyurethane might leave marks on my garage floor, but they roll clean and the two locking wheels hold the shelf steady when I'm loading heavy bins. Screwing them onto the 1" poles took maybe five minutes total.

The locking mechanism on two of these is a lifesaver on my uneven garage floor, and the polyurethane wheels roll silently even under a loaded shelf. Screw-in installation onto my existing poles was straightforward, and the 1" thickness feels solid enough for daily abuse.
