29mm Carbo Clew Block Assembly from HARKEN
29mm Carbo Clew Block Assembly from HARKEN
From the folks who invented ball bearing blocks, this line of blocks boasts an excellent strength-to-weight ratio. 29mm doubles and triples feature a U-lock to hold the swivel in the front or side position, or allow it to spin freely. Use the 40mm blocks for jib and mainsheet systems on high-performance dinghies, and for high-load control lines on small keelboats. The 57mm blocks have an enormous working range that makes them ideal for main and jib sheets, spinnaker halyards and control lines.
