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 A2053 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.
