40 mm Hi-Load Plain Bearing Block for CX25 - 2:1 Halyard, High Load

2:1 halyard block for Seldén CX25 Code Zero furler.

Machined and hard anodized aluminium block with captive pin. Acetal sheave.

To boost the performance when using a Code Zero, the halyard load
must be higher than what normal halyard boxes and stoppers
can handle. Therefore, a 2:1 purchase needs to be arranged by
fixing the dead end of the halyard in the mast and letting it run
through a block attached to the halyard swivel. Position on the
mast must be specified by Seldén. In most cases Code Zero sails
need to be hoisted lower than gennakers and spinnakers.
