Based on the same design as our excellent hardware cases. The sizes shown above are the EXACT internal dimensions of the hardware case. Works on a very simple but effective internal dividing system that is totally adjustable to meet your requirements. The "snaking" divider is attached to the inside of the case via velcro and can create up to 10 compartments. Please note a separate hardware case will be required to transport the rack. Like acoustic drums, we thinks it"s a good idea to separate your drums from your hardware. This case will transport Roland TD3/6"s & Yamaha DTXpress II & III & IV Xplorer
