Smart Cart is a strong, high-capacity cart designed to stand up to rough abuse for many years. The cart features an interchangeable, durable plastic pan that can be snapped out with ease. The frame is satin etched, anodized tubular aluminum alloy, making it both lightweight and extremely strong. Comes in your choice of either a 7- or 12-cubic foot pan, and 20” heavy-duty spoke flat free wheels or wide-tread 16” flat free tires. Comes in green, blue, or black.
