Harken has updated its patent-pending T2™ Blocks with double versions of the 18, 29, 40, and 57 mm sizes, giving sailors the ability to build an even greater array of systems. T2 Doubles share the same styling and all-composite construction as other blocks in the line. The 29, 40, and 57 have no rivets, fasteners, metal parts, or shackles, making them some of the lightest blocks on the market.

"We're working hard to grow the T2 line with the lightest blocks possible without compromising the strength and reliability we're known for," says Harken engineer Matt Schmidt. "With these new T2 Doubles and Ratchamatics, you can build complete systems for your boat that can take the load without the weight of metal shackles."

T2 Blocks have received rave reviews from Olympic and world-class sailors for their reliability and smooth operation. Single and double configurations can be tied, spliced, or lashed to almost anything. Double blocks feature composite line guides in the block head to prevent capsizing. Composite sheaves spin freely on Delrin® ball bearings with curved bearing races for low-friction rolling under high loads. All T2 Blocks are lashed or spliced through the load-bearing center of the block, decreasing sideplate loads and providing extra security. T2 Blocks range from 18 to 57 mm and are ideal for traveler controls, mainsheets, vangs, cascades, and other applications that require small and extremely lightweight blocks.
