Sked Basic Rescue SystemFEATURES Compact storage, ease of use, and flexibility in transport have made Skedco's Sked stretcher popular with fire departments, rescue squads, the military, and ski patrols. Made from a heavy sheet of plastic, the stretcher becomes rigid when folded around your patient. A variety of handles and straps allows the stretcher to be transported by carrying, lifting (vertically or horizontally) by rope systems or helicopter, or towed with the stretcher
