We sell and service many institutional pianos and for their needs, the grand piano stage dolly by Jansen is our first choice. A stage dolly will allow you to regularly move your piano freely, safely, and with less wear and tear. Still, a stage dolly in an investment that you will make one time and then, like most people, you will forget about it. For this reason, we recommend this piano dolly for its high-quality and low-maintenance.
These piano dollies are appropriate for nearly all concert grand pianos approximately 9' in length. The radial arms extend to get the right fit. In most cases, the stage dolly is replacing casters less than 3" in diameter. In this case, you need #6544
In rare cases, if the stage dolly is used to replace large locking brass casters then you will need #6544R. Model #6544R has arms that compensate for the height difference made by these extra-large casters (like the ones pictured).
