Harken 57mm T2 Soft-Attach Double Block
T2 blocks come in single and double configurations and can be tied, spliced, or lashed to almost anything. T2 doubles feature composite line guides that are integrated into the block head. They prevent the block from capsizing by pushing the lashing line to the outer edges of the sideplates. The 29, 40, and 57 mm blocks feature composite sheaves that spin freely on Delrin ball bearings with curved bearing races. They have no metal shackles or rivets, making them the lightest soft-attach blocks Harken has ever designed. All T2 blocks route the attachment line through the block head and sheave, decreasing the loads on the sideplates and acting as a safety backup for the system. Use for traveler controls, mainsheets and vangs, cascades, bridles, and other systems where small lightweight blocks are called for. A length of Spectra line is included.
