It"s hard to imagine an invention more ubiquitous than the wheel, and for keyboard players who need a convenient and affordable way to get their rig rolling, the Keyboard Porter from Road Runner marries the convenience of wheels to a practical and well thought out keyboard case design with the "chops" every player needs to arrive at the gig with minimal hassle. A durable luggage-grade exterior with smooth-glide in-line skate style wheels makes transporting even the bulkiest piano keyboard a breeze, while the case"s plastic wheel guards make curbs, stairs, potholes, and earthquake rubble navigable. The bottom has been reinforced internally with an additional scratch guard near the wheels, while 1" thick dual-layer padding maintains rigidity on the outer side and a comfortable cushion to protect the keyboard on the inside. The rubber comfort-grip handle allows the case to be pulled with ease, and a detachable shoulder strap and quilted grip handle offer additional transport options. Three large expandable pockets provide plenty of storage space for even the most well-provisioned player, with room for a laptop or table top synth, cables, power supplies, sustain pedals, sheet music, groupie address books, small mammals, and other accessories.Luggage grade exterior In-line skate style wheels Plastic wheel guards 1" thick dual-layer padding Rubber comfort-grip handle Detachable shoulder strap 3 expandable pockets
