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 fiber-reinforced composite construction sideplates replace stainless steel straps found in Classic blocks. These densely packed glass fibers reinforce the resin for strength.
These smooth-running powerful performers make trimming easy, no matter how hard the wind blows.
40 mm Carbo Air blocks come in styles to fit any system: singles, doubles, triples, quads; ratchets and fiddles; soft and hard attach.
Perfect for main, jib and spinnaker sheets on dinghies and sportboats; and control lines on boats of all sizes.
