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 and halyard applications, vang and spinnaker control lines on boats to 10m (33ft)
  • S60 - on boats up to 12m (40ft)
