HARKEN 57mm Carbo Double Ratchet Block

Carbo ratchet blocks allow sailors to hand-hold loaded lines and offer balance between holding power and controlled easing. Machined aluminum sheaves are Hard Lube-anodized for strength and corrosion resistance. Eight facets hold line securely.

Switchable ratchets provide precise control with an accessible on/off switch that is easy-to-operate from both sides of the block.
