Block Triple w/Cam & Becket 29mm

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; soft and hard attach. Perfect for main, jib and spinnaker sheets on dinghies and sportboats; control lines on boats of all sizes. 

  Lightweight, strong and reliable fiber-reinforced composite construction. Companions to the popular Harken Black Magic block line, these small, compact blocks have very high working loads for safe, easy trimming. Ball bearings, sheave, and sideplates are UV-stabilized. 

  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.
