Harken 2168.HTE 57mm Carbo Ratchamatic Block - High Tension - 2 x Grip

Harken 57mm Ratchamatic® HTE Block — Swivel, 2x Grip is a high-performance, load-sensing ratchet block designed for maximum control in heavy-air sailing conditions. Featuring the HTE (High Threshold Engage) system and Power3 2x grip, this block delivers powerful holding capability while maintaining smooth, efficient operation.

Under low loads, the block spins freely in both directions for minimal friction and easy trimming. As load increases beyond the higher engagement threshold, the ratchet engages automatically, providing 20:1 holding power. This delayed engagement allows lines to run free longer, making it ideal for spinnaker systems where fast, clean gybes are essential.

The swivel head ensures optimal alignment under changing loads, while the lightweight Carbo construction provides strength and durability without unnecessary weight. The 2x grip version is designed for big breeze and steady conditions, offering maximum control and reduced load on the sailor.
