Stand up spinnaker sheet block. This block typically mounts to the top of the coaming aft and functions for a spinnaker the way a jib or genoa car functions for a headsail. Backing plate included.
Spinnaker sheet blocks for Catalina 22 and Catalina 25
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.
