Hi Discover, these are 75lbs per caster. If there is 4 casters per chair that is a total of 300lbs.
Sal, Thank you for your question. The stem on this caster, in fact, is not removable.
No such socket for that type of caster with stem.
I can pull them out and I guess I should bring one to the store.
no just now submitting
I'm sorry but we do not have this product in a 1-inch version.
