The new Barton Ratchet Block is designed to be used on mainsheet systems and spinnaker sheets on dinghies and keelboats, and for small yachts up to 30 feet. Combining high performance engineering and contemporary design, the 55mm ratchet block is the first in a planned range of sizes, it also offers a stainless steel lever that locks the swivel head if desired. The new Ratchet Block allows sailors to easily hand hold loaded lines and offer balance between holding power and controlled easing. Designed for low friction and longevity in harsh marine environments, the Ratchet Block body is manufactured from a composite of high density nylon and glass fiber reinforced polymer with a high level of UV protection. Internal components are of marine grade 316 stainless steel and the 12 faced aluminium sheave is anodised in gunmetal silver.
