64 mm Series 40 Stainless Fiddle Block - Swivel

Eliminating screws and rivets, these unibody blocks are precision machined from a solid piece of stainless, folded in half and then assembled using non-conductive Delrin on all mating surfaces. Every block now has built-in adjustment that allows the shackle to swivel or lock with a simple set screw. Fiddle blocks are often used with mainsheets or for rope boom vangs.
