Stainless steel cheeks and Acetal sheaves ensure a long service life with virtually no maintenance. Hollow rivets in the block heads can be fitted with shackles, which can also be used to add a becket for extra purchase.

Range Selection Advice
  • Vang, cunningham and trapeze retriever systems on dinghies
  • Leech line tackles, bunk adjusters etc on larger yachts
  • U.V. stabilised Acetal sheaves
  • Grade 316 stainless steel cheeks
