The R16 Ground Glider instantly transforms into any of 8 configurations. Super wide R-Trac 6"x3" front casters with brakes and 8"x3" rear wheels easily roll heavy loads over grass, dirt, and soft carpet. The custom-designed R-Trac Wide wheels feature low profile no-flat tires, lightweight but strong polymer hubs, low rolling resistance, pneumatic-like cushioning, vastly wider load dispersion over soft terrain, and look like racing wheels. 6"x3" brake casters are 50% wider than typical casters and R-Trac 8"x3" rear wheels are 33% wider to glide over soft terrain but keep the cart lower to the ground for better loading ergonomics and smaller storage size. 25% larger tubing on the frame bed and foldable handles is stronger for even bigger loads. Extremely tough textured powder coat finish survives thousands of gigs. Non-skid frame bed surface resists load slippage. Now you can easily roll your gear over the grass at a backyard wedding, an outdoor festival, or sporting event.
