Caster features rolls easily over concrete walltowall carpet or even throw rugs the plasticmetal locking mechanism is quite clever

Once the casters are mounted youll need access to an air compressor and tire gage if a tire ever loses air

I just got two of these and mounted them btw they do not come with mounting bolts so you will have to go get your own

I found that the tire that would not lock at all was actually a little low just barely pressurewise and once that was remedied does indeed work

If you are having a hard time getting the tirerolling part check the pressure apparently they arent necessarily at the proper pressure from the company

I then figured out that the act of pulling the air valve out to measure was releasing air pressure because when i didnt touch it then it would be ok
