This triple block is typically used on the traveler of a Catalina 27 or Catalina 30 equipped with a mid-boom traveler whose traveler car has a three mainsheet attachment points.

Usage:
• Mainsheet block for the Catalina 27
• Mainsheet block for the Catalina 30

If you require three single blocks because your traveler car is equipped with three mainsheet attachment points, choose #K1960 Mainsheet Block Kit w/Single Blocks shown below.

If you require a retrofit kit that includes a triple block to mount on the traveler car, see #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.
