HARKEN 57MM #2600 CARBO SINGLE BLOCK

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.

Blocks feature Cam-Lock or U-Lock locking systems to lock the shackle in front or side positions, or swivel to keep line from twisting.

The high-load 57 mm Carbo has a broad working range. Use for main and jib sheets on centerboard and keelboats like Lightnings, Dragons, Solings, J/24s and for mainsheet systems on catamarans.

Use for: Main/jib sheets, Mainsheet fine-tune, Control lines, Vangs Cunninghams, Outhauls
