Ronstan's range of continuous line furling systems puts great performance and reliability within the reach of cruising and racing sailors alike. The top swivel is the upper half of the system and the fork is designed for use with Ronstan's dedicated torsion line thimble. Ronstan swivel bodies are made from hard anodised grade 6061 T6 aluminium for durability and corrosion protection. Grade 2205 stainless steel is used for the load bearing shaft for optimum strength to weight ratio. This swivel features a fork/fork configuration for direct halyard soft eye attachment, retained pins and a fast pin to facilitate easy changeover of sails sharing a common furler set. Specified weight excludes shackle. Designed to work with standard furler RS280000, it is rated to 16,000kg NBL.
