Harken Carbo AirBlocks
 Harken's long glass fiber injection molding techniques have produced an incredible strength-to weight ratio in a compact block. This is the most significant breakthrough in block design since the ball bearing block was introduced in 1967.
1. Patented Cam-Lock Three-way head locks shackle in front or side positions, or swivels freely to keep line from twisting.
2. High-Load Ball Bearings Low-friction, high-strength ball bearings allow powerful multiple purchase systems.
3. Smooth-Rolling Curved Bearing Races Curved bearing surface fits ball for more ball-to-race contact. Disperses load for higher strength, smaller block.
4. Lightweight, Strong Sideplates Nylon resin sideplates densely packed with long glass fibers replace stainless steel side straps. Blocks 30% lighter with a 60% higher working load than classic.
Glass fiber align with the contours of the block to reinforce sideplate strength. ...more |

Harken Big Boat Blocks
 Black Magic® blocks evolved from the first AirBlocks® developed in 1992 for top level syndicate racers. Using Finite Element Analysis to remove excess material, our engineers produced a block optimized for maximum strength-to-weight. Today these low-friction, efficient, and easily-maintained blocks are used on boats from club racers to the most elite racing machines.
1. Isolated Metals Plastic isolators between dissimilar metals prevent corrosion.
2. Protective Finish Black Hardkote anodizing for scratch-resistant UV protection. Three times tougher than gray. Strong, Lightweight Aluminum sideplates are sculpted for superior strength-to-weight ratio. Edges are radiused to protect line.
3. Caged Rollers Torlon® roller bearings are separated to prevent racking and reduce friction.
