Harken's Carbo fiddle block features high-load ball bearings with fitted races for low-friction operation. The 40 mm fiddle is an excellent choice for a Hobie® 20 barber hauler block, 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.

Carbo AirBlocks® are 60% stronger and 30% lighter than Harken's classic blocks. The nylon-resin sideplates are densely packed with long-glass fibers for a compact block with a high strength-to-weight ratio. Sheaves spin on high-load ball bearings with fitted races for low-friction operation. UV stabilized with black additive for maximum protection.
