Great question! A "K" stem has a height of 1" and a width of 3/8" while a "B" stem has a height of 7/8" and a width of 7/16". Based on the specs you have provided you would need a "B" stem caster. Here is a link to our Chair Caster Guide which provides instructions on measuring your casters and replacing them.
