Harken 29mm Carbo Air Block

The Harken 29mm Carbo Air Block is a lightweight rigging component designed for sailors, rope-access technicians, and automotive enthusiasts who utilize pulley systems or cable-driven applications. This compact air block serves as a redirect in sailing rigging, towing systems, and custom vehicle modifications where precise rope or cable routing is essential.

Constructed with a carbon composite shell, the 29mm Carbo Air Block weighs just 0.1 lbs while maintaining structural integrity under load. The 29mm dimension refers to the sheave diameter, which accommodates standard marine and rigging-grade rope, minimizing bending stresses that could degrade line strength. Harken's engineering focuses on low friction at the sheave bearing, enhancing the efficiency of the system.

This air block is particularly beneficial for mechanics and fabricators installing custom winch systems, cable hoists, or rope-tensioning mechanisms on trucks and off-road vehicles. Its lightweight design is crucial for applications where every ounce matters, ensuring reliability in demanding environments.
