Harken 29mm Double Carbo Air Block

The Harken 29mm Double Carbo Air Block is a precision-engineered rigging solution designed for tactical operations, maritime applications, and high-performance lifting scenarios where load management and directional control are critical. Built by Harken, a manufacturer with decades of marine and tactical heritage, this air block serves operators and teams who demand reliable, lightweight hardware for complex rope work and load distribution.

The 29mm Double Carbo Air Block features dual sheaves with high-efficiency carbon composite construction, minimizing weight while maintaining exceptional load-bearing capacity and low friction characteristics. The "air block" design incorporates open-frame geometry that reduces swinging and maintains stable positioning under dynamic loads—a critical advantage in tactical rappelling, rope rescue, and multi-directional rigging where pivot points must remain predictable.

At just 0.2 lbs, the carbon composite and aluminum construction delivers strength-to-weight performance that meets professional standards while the compact 3 x 2 x 5 inch footprint allows integration into tight operational spaces without adding bulk to your kit. This block is essential for tactical teams, rescue personnel, and military units engaged in demanding environments.
