4" Wheels

The swivel action is silky smooth and the polyurethane wheels roll quietly even on my garage's rough concrete. The locking levers are easy to flip with my foot, and all four lock solidly so the shelf stays put when I'm loading heavy bins.

The locking mechanism on these wheels clicks in place with a reassuring thunk, and the polyurethane rolls so quietly over my garage floor that I keep checking to make sure they're actually moving. Swapped them onto my SHE18308 worktable in ten minutes flat, and now I can glide the whole thing around

Bolted these onto my worktable in about ten minutes and the polyurethane wheels roll smoothly even over the slight lip on my garage floor. The fact that all four lock is a huge plus, since I don't have to chase the table around when I'm working.
