Composite frame with ball bearings for smooth operation. Typically used in our double-ended mainsheet system for boats like the Catalina 22. Also used as the primary mainsheet block mounted on a swivel base on boats equipped with a barney post. These boats include some Omega 14's, the Capri 14.2, and the Coronado 15. It is also a perfect choice for a Capri 16, Capri 18, or Catalina 22 when the boat is equipped with a mid-cockpit barney post.
