These Yamaha grand piano casters are made of solid brass, and sold in a set of 3. The brass socket is built into the wheel, and attaches to your piano via four screw holes. These high quality piano wheels would make great replacement casters for your Yamaha piano--adding a fresh new look and touch of elegance (the thick stem base is very sharp on grand pianos). They would also look great on other brands of pianos as well, as they are not exclusively a Yamaha product.
