For sale I have a ClaviMover, which is a very nice moving dolly for Yamaha Clavinova digital pianos. These are made by a company called Noteworthy Promotions in California. The dolly fits most models of the Yamaha Clavinova, and may fit other similar 88-key piano models, depending on the width and depth of the legs and footings. To determine the fit, measure the inside dimension (width, or spread) between the footings. Also the overall length (front to back) of the footings.
Dimensions of this model are 50" x 17.5". This means that the inside dimension of the footings is 50". If your footings are closer than 50", it will not fit. Maximum length of the footings is 17.5", meaning if your footings are longer than 17.5", it will not fit.
