The HDG Rope K3 Thimble with Master Link is a heavy-duty, integrated connection assembly designed for fiber rope mooring systems. It combines a hot-dip galvanized (HDG) rope thimble with a permanently attached master link, providing a secure, ready-to-use connection point for aquaculture cages, mooring buoys, and marine rigging.
The thimble features side ears that perfectly guide and cradle the fiber rope eye, preventing abrasion and deformation under high tension. The integrated master link eliminates the need for an additional shackle, simplifying installation and reducing the number of connection points—which ultimately enhances the safety and efficiency of the entire mooring system.
