Questions

Caster capacity or wheel capacity?

Complete caster titles top out about 450 lb each. Bare wheels can list much higher with no yoke rating. Use the number on the listing you buy.

4 x 1-1/4 or 4 x 2?

4 x 2 is wider and usually carries more on the same diameter. 4 x 1-1/4 fits tighter carts, racks, and stem mounts where the 2 in tread will not clear.
