Description

50mm Quad Dynamic Block With Becket.

The A2057 is a high performing ball bearing block, designed to eliminate friction and allow rope to run at great speeds.

Ideal for use on Keelboats and Catamarans for a range of applications from jib sheet to mainsheet systems, to backstay tensioning systems and everything in between. The 50mm quad is a great choice for systems which require a larger purchase system with minimal friction.

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 A2057 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. This allows for easy termination of a rope as well as helping keep the load centralised.
