All purpose (AP) blocks are a great all around solution. Self-lubricating Acetal polymer sheaves running on polished stainless steel races perform equally well with dynamic loads and high static loads. For durability and a long service life, these blocks are the right choice for sheets, halyards and control line applications for cruising and racing.

Range Selection Advice
  • Mainsheet
  • Halyard

  • Spinnaker control lines on off-the-beach catamarans, one design classes and sportsboats up to 8m (26ft)
  • U.V. stabilised Acetal sheaves
  • Impact and U.V. resistant, fibre reinforced Nylon cheeks
  • Grade 316 stainless steel bearing race
