Product Description

All purpose (AP) blocks are a great all around solution.

Quick adjusting cleat arms require no tools to adjust and fix securely in position. Becket pin is removable so line can be spliced prior to fitting.

  • Mainsheet and halyard applications, vang and spinnaker control lines on boats to 10m (33ft)
  • S60 – on boats up to 12m (40ft)
  • Typically used in direct 4:1 purchase systems such as mainsheets and boom vangs
  • On larger boats they are used for fine-tune mainsheet tackles, outhauls, cunninghams, checkstays, genoa lead pullers and traveller controls.

  • Grade 316 stainless steel load strap
  • Impact and UV resistant, fiber reinforced Nylon cheeks

When I order my bracket, I put the wrong mailing address. So the post office returned it to Fast Boat Parts. Armen the rep. For Fast Boat Parts, Immediately returned my call & has been doing a great job of watching for the returned bracket, keeping me informed of the status. The first bracket was delivered quickly & Armen has been very nice & thoughtful in assisting me with getting another bracket mailed to my correct address.
