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
