MultiMix F doubler is the newly modified double blade rope whose structure is made to enhance its maximum strength.
Since this rope is a compound of polyester and polypropylene, it has not only the high resistance of water, weather and abrasion, but has excellent workability due to its lightweight and floating characteristics.
