The Carbo fiddle block 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 switch allows the shackle to lock at 90-degree intervals or to swivel freely.
