Boats such as the Catalina 22 or Catalina 25 that have a pop top can benefit from the convenience of a quick release when the pop top is raised. Others may want to remove the bottom block from the mast so it can be moved outboard for use as a preventer on a long downwind run.

If you would like to upgrade any of our stainless steel boom vang kits with this snapshackle equipped block, just give our sales staff a call. We'll swap blocks for you and credit the value of the standard screw pin shackle block toward the upgrade.

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.

Approximate Dimensions:
• Shackle pin diameter: 3/16"
• Sheave diameter: 2"
• Maximum line diameter: 3/8"
• Bearings: Delrin
• Safe working load: 1150 pounds

Only appropriate for the Capri 16, Capri 18, Capri 22, Catalina 22, Catalina 25 Catalina 250 and the Capri 26.
