These Harken soft-attach blocks are engineered for high performance and minimal weight. The 18 mm model utilizes stainless steel components for durability, while the 40 mm model employs composite materials to achieve the lightest design in its category. Both variants are optimized for strength-to-weight ratios, ensuring efficient operation on deck.
18 mm Construction: Features stainless steel ball bearings and an integrated stainless inner race and rivet for optimal strength-to-weight.
40 mm Sheaves: Composite sheaves spin freely on Delrin ball bearings with curved bearing races.
Weight Optimization: The 40 mm blocks have no metal shackles or rivets, making them the lightest soft-attach blocks Harken has ever designed.
