Low-friction 40 mm Carbo Air blocks are lightweight, strong, reliable and affordable.
Companions to the popular Harken Black Magic block line, these small, compact blocks have very high working loads for safe, easy trimming.
Lightweight, strong and reliable fibre-reinforced composite construction side plates replace stainless steel straps found in Classic blocks. These densely packed glass fibres reinforce the resin for strength.
These smooth-running, powerful performers make trimming easy, no matter how hard the wind blows.
40mm Carbo Air blocks come in styles to fit any system: singles, doubles, triples, quads, ratchets, and fiddles, with soft and hard attachments.
Perfect for main, jib and spinnaker sheets on dinghies and sportboats and control lines on boats of all sizes.
Cam arm locking plates allow the cam arms to be locked in more than five positions for fair leads. This is perfect for highly loaded control lines on small keelboats.
An excellent choice for 4:1 tackles on dinghy vangs and mainsheets, as well as for controls such as cunninghams and internal boom outhauls on larger boats.
