Transport patients faster and with fewer rescuers. Attaches to almost any rigid litter with a top rail in less than 30 seconds and rolls easily over trails and moderate terrain. Because it clamps to the top rail, the Russ Anderson Universal Litter Wheel will fit a wide variety of litters including the plastic litters and the metal litters that have the flat metal straps for bottom rails. The wheel uses an all-terrain tire that provides comfort and stability. Unique locking device "clamps" the frame to the litter.
