This provides a superior load-carrying ability and longevity when compared to other bearing systems available on the market.Swivel Lock Ð The A2068 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 Ð This pulley features a central becket between the sheaves.
