This Harken 75 mm Carbo Ratchet block with swivel is developed for controlled handling of lines under high loads, where grip, control, and efficient power transfer are essential.
The ratchet function helps the sailor hold loaded lines more securely, while the 8-sided Hardkote-anodized and Teflon®-impregnated sheave provides effective friction braking at 180 degrees.
The block is suitable for sheeting and line handling on board, where low weight, high holding power, and precise control are important features.
