Review on Enhance Mobility with POWERTEC 17053 Industrial Caster - 8 Inch by Chris Burks

I use these for our high school marching band wagon. I have four of these in the corners and two pneumatic ones in the middle. You have to carry 500 pounds. everyone, and I don't get close to giving them that much importance. I was fortunate to get a season with them before they wore out completely and needed replacing. So I end up doing a few sets a year.
