    • The Harken 2159 T2 Ratchamatic features T2 Series styling and soft-attachment system
    • The weight of this high-strength block is only a few ounces
    • This is thanks to composite fiber-reinforced sideplates, hardcoat-anodized aluminum sheave, a lightweight soft-attach, and a minimum of moving parts in the ratcheting mechanism
    • All T2 blocks are lashed or spliced through the load-bearing center of the block, decreasing the loads on the sideplates and acting as a safety backup for the system
    • Lashing allows ratchet adjustment close to the deck
    • Lashing or splicing provides a variety of options for securing the block at exactly the right height to maintain a fair lead
    • Pressure on the line engages the ratchet mechanism, which switches seamlessly from free-running to ratchet mode
    • Unloaded main and jib sheets run out freely during mark roundings, and asymmetrical spinnaker sheets free instantly during jibes
    • T2 Ratchamatic blocks are clearly labeled with high-contrast directional markers for correct reeving and trimming direction
    • Use for mainsheet and spinnaker systems on beachcats, dinghies, and sportboats
    • A length of Spectra® line with a polyester cover is included.
