Rotator Arm; Downhaul Blocks; Halyards - Nacra 500 Owner's Manual

Place the plastic spreader cover over the spreader tip and place
the diamond wire in the slot in the spreader tip with the nylon
roller above the spreader arms. Feed the monel seizing wire from
the back side of the tip with on end on each side of the diamond
wire. Lead the wire out of the tip.
Cross the seizing wire over the diamond wire and feed to the
back of the tip. Pull and twist tight with needle-nosed pliers.
Check the wire to be sure that it is held tightly in the slot, and
cannot come out (6).
NOTE: Be sure to tape all split rings to prevent snagging and
accidental loosening.
