Harken T2 soft attach blocks are made from a high strength composite material. The Harken T2 blocks were the first blocks on the sailing market with no metal shackles or rivets. These versatile blocks can be used for traveler controls, mainsheets, kickers, vangs, cascades, bridles, and many other sailing systems where small, lightweight blocks are needed. T2 blocks can be tied, spliced or lashed to almost anything on your sailing dinghy. A length of dyneema rope is included with each block.
