Allen Brothers 50mm Double Dynamic Block
Allen Brothers 50mm Double Dynamic Block
50mm Double Dynamic Block.
The A2052 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 double 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 A2052 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, perfect as a tie-off point when being used in a cascade system.
