• Construction: Double braid continuous strand line without mill splices (see "Technical Support" below for the full story)

To prevent the line from twisting or binding when used in a cascade or mainsheet system this block is supplied with a feature to lock the rotation of the shackle that is on top of the body of the block. With the use of an Allen wrench, tighten the set screw to lock the shackle in position. When used as a swiveling block, ensure the set screw is not tightened and the swiveling shackle can self-align to find the fairest lead.

The length of this item is based on the original factory specifications. However, the previous owner, like Captain Jack Sparrow, may have had an entirely different idea about how to rig a boat! Please confirm this is the correct length for your particular boat. We cut it from a long length and can't splice it back together again. Your order cannot be canceled, returned or exchanged, but, like Jack, you may have a different idea of what you can use it for!
