I ordered these (3" model) hoping to replace the 3" casters that came with the kitchen cart. However, the wagon's own wheels were black rubber and gave off a lingering, overpowering odor. Since Bayite casters have polyurethane wheels that are virtually odorless, I wanted to replace those smelly ones. Advertised wheel, plate and axle sizes seem to fit. When the Bayite rollers arrived (quickly and well packaged) I found that they were in fact virtually odorless and looked very well made. However, I had to return them as the (very strong) brake levers are much longer than I expected and they will not work in my application. (Dimensions with brake lever weren't listed in the product description I believe.) Otherwise they seem excellent and should work well anywhere brake lever size isn't a concern.
