Carbo Air Blocks are 60% stronger and 30% lighter than our classic blocks. Use the Harken 2636 Carbo Single Block With Swivel 40mm for jib and mainsheet systems on high-performance dinghies and for loaded control lines on small keelboats. 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. Ball bearings, sheave and sideplates UV stabilized with black additive for maximum protection. This Harken block is great for main and jib sheets, mainsheet fine-tune, control lines, vangs, cunninghams and outhauls.
