Harken 45mm Double Element Block w/Swivel

The Harken 45mm Double Element Block with Swivel (MPN 6238) is a precision rigging pulley system engineered for demanding marine, offshore, and tactical load-handling applications. The Element design combines forged aluminum sideplates with compound curves that deliver exceptional strength-to-weight efficiency, making it the optimal choice for operators who require reliable mechanical advantage without unnecessary bulk or premium pricing.

The double-element configuration delivers 2:1 mechanical advantage, allowing users to manage heavier loads with reduced physical effort—critical for tactical rescue, equipment deployment, and field rigging where efficiency directly impacts mission success. The 45mm width accommodates standard rope diameters while the proven journal bearing provides smooth, consistent rotation under load. Hardcoat anodizing on all aluminum surfaces resists corrosion from saltwater, humidity, and harsh environmental exposure, ensuring sustained performance in coastal, maritime, and high-moisture operational environments. The integrated swivel prevents rope twist and tangling during dynamic load shifts, a practical feature that reduces operator fatigue during extended operations.

This block suits tactical teams conducting vertical insertion, maritime salvage, offshore rigging, and expeditionary load management. Its compact footprint (3 x 2 x 5 inches) and minimal weight (0.4 lbs) make it pack-efficient for rapid deployment and VBSS (Visit, Board, Search, Seizure) operations. The Element block represents Harken's market positioning for operators demanding production-grade reliability at accessible cost, without compromise on load capacity or corrosion resistance.
