Low-friction Carbo Air blocks are lightweight, strong, reliable, and affordable. Companions to our popular Harken Big Boat blocks, these small, compact blocks have very high working loads for safe, easy trimming.
These smooth-running powerful performers make trimming easy, no matter how hard the wind blows. Carbo Air blocks are made of tough reinforced composite in size and style to fit any system: singles, doubles, triples, quads, and quints; ratchets and fiddles; soft and hard attach; 18 - 75 mm. Perfect for main, jib, and spinnaker sheets on dinghies and sport boats; control lines on boats of all sizes.
