The 1R4417W for 61-note keyboards is designed for keyboard players who are looking for the best protection for their delicate musical instruments. It is rotationally molded from Linear Low Density Polyethylene (LLDPE), offering high durability and strength and features SKB's proprietary glass reinforced nylon trigger latches with TSA locks, enabling musicians to safely lock the case and still have it inspected by airline security personnel. SKB is the only case manufacturer to utilize this technology. The 1R4417W features a combination foam/cleat interior, which holds the instrument securely during transport. Adhesive backed foam for the interior lid is provided loose, so the musician can customize the fit of the case to match the keyboard. Special, reinforced bridging in the lid gives this case the strength to withstand the most demanding tours. This 61-note size case case is designed for keyboards such as the Korg TR61, Roland Fantom G6, and Yamaha MOTIF XS6. This case features built-in wheels, offering tilt-and-go transport, and is water resistant making it excellent for inclement weather.
