Toggle Deductions/Stay Into Foil Options
Most boats have a chainplate with a single tang.
If boat has two plates forming a jaw, reverse
eye/jaw toggle so eye is down.
Important! Remove black plastic caps and
install them so crosspin will be 90 degrees
to lower clevis pin.

Options for Snaking Stay into Foils
Use dimensions of Harken toggle below to build stay to correct length.
Tip: Turnbuckles should be 1/2 to 2/3rds open to allow shortening for new wire stretch and for
fine-tuning mast rake.
1. Swage stud at end of wire.
2. Open end of wire and install Norseman or Sta-Lok
®
stud after foil is assembled.
3. When using smaller wires, marine eye may fit. See page 12.
4. Rod adapter nosepiece for Harken rod adapter stud.
WARNING! Using a threaded nosepiece with only
adhesive at the upper rod eye terminal may result
in headstay system failure which can cause an
accident, damage to your vessel, personal injury,
or death. See www.harken.com/en/general-warn-
ings-instructions/ for additional safety information.
