Drive Medical's Lightweight Expedition Transport Wheelchair weighs an impressively low 19lbs, yet it is expertly designed to safely and effectively support up to 300lbs. Featuring 12" rear flat tires that can navigate both indoor and outdoor terrain, the aluminum Expedition is versatile and reliable. Easy to use companion activated wheel locks and seatbelt ensure safety, while a simple lever on the chair back allows for quick, flat transport and storage. Adjust the length of the footrests, loosen the bolt (or knob) on the telescoping tube shaft. Tighten securely after adjustment. The lowest part of the footrest should not be less than 2 1/2 inches from the ground to permit proper clearance
