Key Selling Points & Advantages
High-Density Pure Lead, Fast Sinking
· Pure lead material: Made from high-purity lead ingots for dense ballast and minimal water resistance, sinking faster than iron or plastic substitutes.

· Corrosion resistant: Lead naturally resists rust and saltwater corrosion,ensuring long service life in both freshwater and marine environments.

· Tool-free fitting: Simply press the rope into the slot and squeeze — the lead body closes firmly around the line in seconds,greatly reducing rigging time.
