Features

Features:

  • 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.
