2 inch bolt on hard rubber casters (set of 4) with small top plate, fits Wurlitzer 1050 and Sonata. Does not fit Rock-Ola 1000.  Our normal bolt on casters have a much larger top plate, this plate specifically designed to fit these boxes.

Part Number 66-7107

Unlike the casters found at local home improvement stores or online discount sites, Victory Glass casters have the correct weight ratings to prevent the wheels from developing flat spots. Our casters are also MADE IN THE USA!
