Unfortunately GRK has discontinued these square grand piano leg dollies, and they are no longer available for purchase. The American company Paul Jansen (famous for their artist benches), manufactures square leg dollies (which are a higher quality and heavier duty than these GRK dollies). You can view them on our website by clikcing the following link:
Jansen Square Grand Piano Leg Dollies
Set of 3 cast iron Piano Leg Dollies with four ball bearing 2" rubber wheel casters on each dolly. The casters are designed for pianos with square legs, to make moving easy. When not in use, they require minimal storage area.
These piano leg dollies are very functional, especially for moving your piano in the home or studio, when you only need to move the piano a short distance. To use, remove the original piano leg casters, and replace them with these. Note designed to be used in place of a grnad piano truck.
