This Harken Carbo Ratchamatic HTE block 57 mm is an automatic load-sensing ratchet block with a single swivel for efficient line handling while sailing.
The block runs freely in both directions under low loads and automatically engages the ratchet function under higher loads. The HTE version has a later engagement point than standard Ratchamatic blocks, allowing for longer free-running.
The load sensor can be adjusted as needed, and the block is constructed with an 8-sided Hardkote-anodized and Teflon-impregnated contact surface for strong grip and controlled line handling.
