  • Wire sizes do not apply to Dyform wire; contact Harken if the rod is other than Nitronic 50. Carbon units use rod only.
  • ‡ Continuous rod only – if sectional, order Unit 4.5.
  • All units take #6 luff tape (6/32 in, 5 mm). Order one extra connector for each extra foil extrusion.
  • Code Zero furling needs very high luff tension; the lower unit has a quick sail disconnect (spring-loaded button) and the sheave arms open to remove the line for quick unfurling.
