Since casualties vary in size, so do North American Rescue’s litters. Designed to safely evacuate larger patients with both comfort and ease, The OSL™ OverSized Litter has an increased patient surface area, extra padded carrying handles, flame-retardant cover, and additional stirrups offering firmer patient support as well as better weight distribution on the floor. Like the Raven®90C, the OSL™ has a bi-fold configuration. The cover material is a very durable Nomex/Kevlar blend.
