Designed for use as a low-friction mainsheet system on sports catamarans, but suitable for many other applications, including backstay tensioning on keelboats.
For a complete 11:1 or 12:1 mainsheet system, you will need:
A2169 – Pro-Ratchet 60mm Quint Block.
A20401S – 40mm Dynamic Single Block With Strap.
Bearings – Dynamic Blocks feature our patented bearing system, which uses twin rows of stainless-steel ball bearings running on a stainless-steel rail. This offers superior load-carrying ability and longevity compared to other bearing systems available on the market.
Swivel Lock – The A2069B comes with a removable swivel lock moulding. When installed, the shackle can be locked in 90-degree orientations. When removed, the attachment shackle can spin freely.
Becket – This pulley features a central becket between the sheaves. The becket can be removed by undoing the split ring. This allows for easy termination of a spliced rope or the addition of another block to increase the purchase system.
