The Harken 2151 T2 is constructed with durable composite material, eliminating the need for metal components or fasteners. Its versatility enables it to be used in various configurations such as traveler controls, mainsheets, vangs, cascades, bridles, and other systems that require compact and lightweight blocks. The T2 Loops feature a convenient on/off loop system that smoothly glides through the block head and around the anchor post for a secure attachment. It comes equipped with a SK75 Dyneema loop, and additional loops are also available for purchase. With its high-strength composite design, the T2™ is the first block to completely eliminate metal shackles or rivets, making it the perfect choice for traveler controls, mainsheets, vangs, cascades, bridles, and other systems that require compact and lightweight blocks. The T2 can be easily tied, spliced, or lashed to almost anything and includes a length of Spectra® line.
