Harken 45mm Double Element Block w/Swivel

The 45mm Double Element Block with Swivel is an essential component for marine and boating applications, designed to provide exceptional strength and durability in demanding environments. Crafted with precision, this block ensures reliable performance whether you're sailing, anchoring, or handling heavy loads on your vessel.

Robust Construction for Marine Use

The Element Block features sideplates that intricately combine forged aluminum with compound curves, delivering unparalleled strength while maintaining a sleek, contemporary design. This robust construction not only ensures longevity but also withstands harsh marine conditions, including exposure to saltwater and extreme weather.

Advanced Swivel Mechanism

Equipped with a precision-engineered swivel, the block allows seamless rotation of lines, reducing chafing and extending the life of your ropes. The design minimizes the amount of metal used to protect the sheave, ensuring optimal performance without unnecessary bulk. Additionally, the proven journal bearing enhances smooth operation and load distribution.

Corrosion-Resistant Features

To combat the corrosive effects of the marine environment, the sideplates are treated with a hardcoat anodizing process. This finish not only provides a robust protective layer but also maintains the block's aesthetic appeal over time. The composite bearing sheave is specifically designed to resist corrosion, ensuring a long service life even in the most corrosive marine conditions.
