The Harken 75 mm Ratchet Block Swivel 2670 is designed for high-load trimming applications where control, grip and smooth handling are essential. Built for larger mainsheets, spinnaker sheets and control lines, the oversized 75 mm sheave provides excellent rope management while reducing friction and trimming effort under load.
The integrated ratchet mechanism automatically engages as loads increase, delivering reliable holding power without sacrificing smooth release when loads ease. Combined with a swivel head, the block self-aligns with changing lead angles, improving efficiency and minimising line wear during dynamic sailing conditions.
Ideal for keelboats, sportsboats and high-performance yachts, the Harken 75 mm Ratchet Block Swivel 2670 delivers dependable load control, durability and refined trimming performance backed by Harken’s proven engineering.
