The height-adjustable Yamaha Tough Terrain Frame is built to support Yamaha's YX-500F Xylophone on and off the field. The Tough-Terrain Frame has welded steel construction and the carrier's 10" pneumatic tires protect your marimba from the rigors of transport. The wheeled xylophone frame's minimal number of adjustments eliminates loosening and subsequent loss of parts. The Yamaha carrier frame has 2 lower crossbars that protect your xylophone's resonators from damage, and a removable accessory bar that accommodates all parallel multi-clamps on the market, as well as all Yamaha rack clamps. The Yamaha Tough-Terrain Xylophone Frame promotes proper playing technique and comfort, due to its adjustable height, and sturdy design.
