50mm Quint Dynamic Block.

Designed for use as a low friction mainsheet system on sports catamarans, but suitable for many other applications including backstay tensioning on keelboats.

Bearings ?? Dynamic Blocks feature our patented bearing system which uses twin rows of stainless-steel ball bearings running on a stainless-steel rail. This provides a superior load-carrying ability and longevity when compared to other bearing systems available on the market.

Swivel Lock ?? The A2059 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 ?? A large central hole not only reduces the overall weight of the block but also offers a rope friendly attachment point.
