Harken 45mm Double Element Block w/Swivel & Becket

The Harken 45mm Double Element Block with Swivel and Becket (MPN 6239) is a rigging component engineered for high-load applications where lightweight strength and compact size are essential. Element blocks use forged aluminum sideplates paired with compound curves to deliver maximum load-bearing capacity while minimizing weight—a critical advantage in marine, aerospace, tactical load-bearing, and field recovery operations where every pound matters.

The 45mm double element configuration incorporates a proven journal bearing system designed to handle the mechanical loads and direction changes inherent in multi-line rigging. The sideplates are hardcoat-anodized, providing corrosion resistance in saltwater, humid field conditions, and exposure to fuel and hydraulic fluids. The integrated swivel reduces torque buildup in the line while the becket attachment point allows direct anchoring without additional hardware, streamlining deployment and reducing failure points in critical systems.

Operators and riggers working in offshore, mountainous, or austere environments depend on Harken Element blocks where corrosion, vibration, and repetitive mechanical stress demand proven engineering. Military units conducting field extractions, marine personnel managing deck operations, and technical rescue teams value the 45mm configuration for its balance of load capacity and maneuverability. At 0.45 lbs with compact 3×3×6-inch dimensions, this block integrates into existing tackle systems without compromising mobility or adding unnecessary bulk to already-loaded rigs.

Harken's Element series represents a shift in block design philosophy—combining the durability of traditional forged construction with contemporary materials science to deliver strength-to-weight ratios that significantly reduce overall rig weight and cost compared to older block designs. For operators who understand that efficiency in rigging translates directly to mission success, the 45mm Double Element Block delivers measurable advantages in real-world conditions.
