The 40 mm fiddle is an excellent choice for 3:1 and 4:1 tackles on dinghy vangs and mainsheets, as well as for controls such as cunninghams and internal boom outhauls on larger boats. The 57 mm fiddle features the Cam-Lock locking system. The switch allows the shackle to lock at 90-degree intervals or to swivel freely. Ratchet Blocks The 57 and 75 mm switchable ratchet blocks provide precise on/off control with accessible, easy-to-operate on/off switches on both sides of the block.
