Harken T2 Soft-Attach Ratchamatic Block - 40 mm (1 9/16") - 2159

The Harken 2159 40 mm T2 Ratchamatic Block features T2 Series styling and a soft-attachment system. The weight of this high-strength block is only a few ounces and is used for mainsheet and spinnaker systems on beachcats, dinghies, and sportboats.

Features:

• 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
• A length of Spectra® line with a polyester cover is included
