Introducing the Harken 2621-2624 3pc Set of AirBlock 57mm Fiddle Line Cam Locks by Harken, a leading manufacturer of innovative sailing hardware. This set includes three individual cam locks, specifically modeled as the 2621 and 2624 AirBlocks.

The Harken AirBlock system is renowned for its sleek design and exceptional performance. These cam locks feature a self-contained, low-profile design that minimizes windage and reduces drag, making them an ideal choice for competitive sailors and those seeking optimal boat speed.

Each cam lock in this set is 57mm in length and is designed to accommodate fiddle lines with a diameter of up to 12mm. The cam locks are made of high-quality marine-grade aluminum and are anodized for superior durability and corrosion resistance.

The 2621 and 2624 AirBlocks are engineered with Harken's patented cam design, which delivers smooth and positive line release. The cams are adjustable, allowing you to fine-tune the tension to suit your preferences and sailing conditions.

This set also includes Harken's signature cam locks with the QuickRelease feature, allowing for easy line release in a hurry. The QuickRelease mechanism is activated by a simple turn of the cam handle, which then releases the line without the need for additional tools or manual tension adjustments.

The Harken 2621-2624 3pc Set of AirBlock 57mm Fiddle Line Cam Locks is the perfect addition to any sailboat looking to enhance its performance and efficiency on the water. Their sleek design, durable construction, and adjustable tension make them a must-have for sailors seeking the competitive edge.
