Z-SPAR Exit Blocks

Exit Blocks incorporate a sheave, and are used to exit any internal control line (halyards, pole lifts, etc.) from a spar where a directional change of 90 to 180 degrees is required. Z-Spar Exit Blocks all attach to the mast with two (2) fasteners. Other Exit Blocks are available for replacement or exact matching purposes. See: Exit Blocks or, depending on the kind of spars you have, See also: Kenyon Exit Blocks, or Isomat Exit Blocks.

For Replacement Sheaves for these Exit Blocks, See Z-Spar Sheaves.
See Z-Spar Exit Plates for in-line exit applications (Halyard Exits) where there is no directional change.
See also: Z-Spar Jib Boxes.
