Harken Carbo Fiddle Blocks

The Carbo fiddle line features high-load ball bearings with fitted races for low-friction operation. 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 patented switch allows the jaw to lock at 90-degree intervals, or to swivel freely.

Ratchets
The 57 mm and 75 mm switchable ratchets provide precise on/off control with accessible, easy-to-operate on/off switches on both sides of the block.
