The "Mother Of All Dollies" is the first true piano moving dolly. With the finest German casters and a 2640 lb capacity, it is designed and built with the heaviest pianos in mind.  An Upright Piano Brace folds neatly into the base and provides great stability with support under the key-bed. E track fittings ensures your piano is secure. Easily lock two of the castering wheels to provide a straight-line path while maintaining steerability maneuvering down hallways or on a sloping sidewalk. The Holzter "Sure Grip" caps provide an unparalleled non slip platform.
