Inquiry (采购产品): ball casters Do you make a ball caster that has a rubberized ball as opposed to a steel ball? We are trying to find the type of design that you ball casters have but we are using them for something that will roll on concrete or sidewalks and would like for the ball to be rubberized. **** Hidden Message ***** Donna Caldwell VA 24153 USA Company: personal E-mail: donnacdac@adelphia.net **** Hidden Message ***** donnacdac@adelphia.net
