Harken 40mm Double Carbo T2 Block40 mm 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.
