CMC Rescue - SRT Throwline-292957 Developed for swiftwater rescue technicians needing the versatility of a throwline with a larger diameter for a better grip, the SRT Throwline is supple enough to fit into a compact throw bag, but has extra strength and is easy to grip when setting tension diagonals or boat lines. The polypropylene core and protective nylon sheath combination produces a strong, supple, highly visible river rescue rope that floats. Rope is sold by the foot. Please contact customer support for maximum length available. Throwlines: A Safe Choice A throwline bag is the safest way to reach a subject in fast-moving or still water. It provides a downstream safety backup when rescuers must enter the water. Throwbags should be kept in patrol cars, ambulances, and other emergency response vehicles.
