Carbo Air Blocks - 40mm
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 a 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 sportboats; control lines on boats of all sizes.
High-strength pivoting lead blocks with cams are used for halyard controls on larger keelboats and as “headknockers” on dinghies and beachcats for sheeting directly from the boom. Hole spacing and rivet size are the same as Classic models, making upgrades easy. Cam reverses for either up or down cleating.
