The MRD175 throw bag is designed for water rescue professionals to allow for maximum throwing efficiency and ease of re-loading even with a gloved hand. The 75' rope is 3/8" in diameter, floats, and has a minimum 2000 lb. breaking strength with a nylon core and polypropylene, yellow and orange weave sheath. The MRD175 is a true 75' from knot end to knot end, making distance measuring much easier.
