Review on Pneumatic Swivel Plate Casters for Efficient Material Handling by Adam Rogers

I couldn't believe how cheap it was. I was afraid it wouldn't work for what we use them for. We have a cart that we put track mats on that has a broken caster. I installed two to make sure they were the same height and easy to move. The mats weigh several hundred pounds and the casters work perfectly. Would definitely recommend and buy again and might need it at some point lol.
