Harken Carbo Airblock #2624
Low-friction Carbo AirBlocks® are lightweight, strong, reliable—and affordable. These are features all sailors look for when choosing sail controls and a real breakthrough in block design. Companions to Harken’s® popular Black Magic® line, these small, compact blocks have very high working loads for safe, easy trimming no matter how hard the wind blows. The nylon-resin sideplates are densely packed with long-glass fibers for a compact block with a high strength-to-weight ratio. Sheaves spin on high-load ball bearings with fitted races for low-friction operation. Ball bearings, sheave and sideplates UV stabilized with black additive for maximum protection. Carbo blocks are perfect for the small-diameter hard lines favored by racers.
Carbo AirBlocks® are 60% stronger and 30% lighter than Harken’s classic blocks.
The Harken Carbo fiddle line features high-load ball bearings with fitted races for low-friction operation. The 57 mm fiddle features the Cam-Lock locking system. The patented switch allows the jaw to lock at 90-degree intervals, or to swivel freely.
