The 3 x 19 (3 strands, 19 wires per strand) galvanized jacketed wire rope construction with swaged socket terminations is the accepted standard for underwater mooring installations.

Developed at the Woods Hole Oceanographic Institution, this high performance rope is torque resistant to prevent rotation and unwinding, and provides superior handling control.

A durable plastic jacket protects against corrosion for increased mooring longevity.

Reduce Drag & Improve Depth Control

Mooring performance is also improved as the wire rope's low drag coefficient allows better depth control of the top buoy and in-line mounted instrumentation.
