PROTON®-8

Proton-8 is a high-strength, and low-weight line that has excellent heat resistance and the grip necessary for use on bitts and capstans. Its firm, flexible, torque-free construction performs well on both single- and split-drum winches. Proton-8 provides substantially better service life, is almost neutrally buoyant, and has low water absorption for ease and speed of handling during deployment and retrieval. The yellow Samthane coating ensures maximum wear resistance and service life while making Proton-8 highly visible. Proton-8 is designed for use on H-bitts and capstans under surging and rendering conditions.
