Completely Different Q

[Sonor]

Casters - if they say they are rated for 300 lbs  but you need four of them, is that a max load of 1200 lbs when using all four?  Or is there some equation of what the load should be?  Or reverse it, lets say you have a cabinet that with full load weighs 1000 lbs. will four 300 lb load casters be sufficient?

Short answer is yes, 4 would be sufficient.

You could also do it with one 1000lb caster, but you might notice some stability issues
