Harken 40mm Carbo Air Block w/Cam Cleat

The Harken 40mm Carbo Air Block w/Cam Cleat is a precision mechanical control component engineered for applications demanding reliable line tension and cleat functionality. Originally designed for marine rigging systems, this lightweight block has also proven useful among powersports enthusiasts and custom vehicle builders who prioritize weight reduction and mechanical efficiency in their suspension or control systems.

Constructed from reinforced carbon composite (Carbo) material, this block delivers an exceptional strength-to-weight ratio, making it ideal for weight-conscious builds without sacrificing durability. The integrated cam cleat mechanism provides positive line lock and release control, allowing single-handed operation that's critical for systems requiring quick adjustment under load. The precision-machined design ensures smooth bearing action and repeatable engagement.

Automotive enthusiasts leveraging block-and-tackle or mechanical advantage systems will appreciate this component's reliability and minimal footprint in custom suspension, cable management, or winch applications. The compact 40mm form factor makes it ideal for space-constrained installations where traditional larger blocks would compromise clearance or add unnecessary mass to critical areas.
