I need to build a few things with wheels on them, and I'd like nice casters. I know Colson has some good options, but am dizzy from looking in their catalog. What are some good choices for caster boards that will hold loads of maybe 400lbs max? Seems like 4" is pretty standard, and I definitely want easy rolling, which I assume means some kind of ball or roller bearing rather than bushings.
Thanks!
Thanks!
