The 57 mm diameter lineup of Carbo Air blocks are low-friction, lightweight, strong, reliable and affordable.
Companions to the popular Harken Black Magic block line, these blocks have very high working loads for safe, easy trimming.
Lightweight, strong and reliable fiber-reinforced composite construction sideplates replace stainless steel straps. 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.
57 mm Carbo Air blocks are of a size and style that will fit any system: singles, doubles, triples, quads, and quints; ratchets and fiddles; soft and hard attach.
Perfect for main, jib and spinnaker sheets on dinghies, sportboats and small keelboats; and control lines on boats of all sizes.
Ball bearings, sheave, and sideplates are UV-stabilized.
