Harken 45mm Single Element Block w/Swivel

Enhance your marine rigging with our 45mm Single Element Block with Swivel, engineered for durability and optimal performance on the water. Whether you're sailing, fishing, or enjoying recreational boating, this block ensures reliable operation in diverse marine environments.

Design & Construction

Our single element blocks feature sideplates crafted from forged aluminum combined with compound curves, providing exceptional strength and a modern, robust appearance. The innovative design utilizes the minimal amount of metal necessary to protect the sheave, paired with a proven journal bearing system. This efficient construction not only maximizes performance but also offers significant cost savings compared to our previous blocks of similar size.

Corrosion Resistance

Designed for the harsh marine environment, the sideplates undergo a hardcoat anodizing process to resist corrosion effectively. Additionally, the tough composite bearing sheave ensures long-term durability, maintaining performance and reliability even in saltwater conditions.
