Allen 60mm Quint Dynamic Block With Becket.

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 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.
