Simply install the new chainplate and replace the existing backstay with the hardware provided.

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.

This backstay no longer includes a pigtail option as there are safer and better alternatives to a pigtail. We recommend using a boom topping lift (better) or a Boomkicker (best) for added performance and safety.
