This kit is typically used to retrofit a Catalina 27 or Catalina 30 equipped with a mid-boom traveler whose new traveler car is equipped with three mainsheet. attachment points.

For a kit which substitutes a single triple block for the traveler, choose #K1841 Mainsheet Block Kit w/Triple Block shown below.

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.
