Harken 2146 T2 Soft Attach Block, 29mm
Harken 2146 T2 Soft Attach Block, 29mm
Our Price: $27.99

T2™ Soft-Attach Carbo, 29mm

The high-strength composite T2™ is the first block with no metal shackles or rivets and is the lightest soft-attach block Harken has ever designed. T2 blocks come in two styles. One uses a loop, the other a length of line. Both methods route the attachment line through the block head and sheave, decreasing the load on the sideplates and acting as a backup for the system. Soft attachments articulate to align with the load for a fair lead, reducing friction. The composite sheave spins on ball bearings with curved bearing races for low-friction rolling. Composite sideplates are fiber-reinforced, high-strength nylon resin. Ball bearings, sheave, and sideplates are UV-stabilized for maximum lifespan. T2 Loop No knots, splices, or tools are needed. Just slide the loop through the block head and over the anchor post for a secure connection. T2 Loops come in 40 mm and 57 mm single sizes. A SK75 Dyneema® loop is included. Replacement loops available. T2 The T2 can be tied, spliced, or lashed to almost anything. Use for traveler controls, mainsheet and vang systems, cascades, bridles, and more. The T2 comes in 29, 40, and 57 mm sizes. A length of line is included. Suitable for Force 5 Vang applications Alternate w/ SS shackle HAR340 more info
