■ Adjusting Foil Length
The length of the furling system is matched to the headstay length by adjusting the
number of 7' (2.13 m) foil extrusions used and by cutting the top foil to length from
one of the 7' (2.13 m) foils provided. In some cases the bottom foil is also shortened.
Consult the chart on page 11 to determine how many full length 7' (2.13 m) foils
you need and save these. You should have an additional 7' (2.13 m) foil to be used
for the top foil which will be 7' (2.13 m) or less.
■ Foil Length - Read Before Cutting Foil
The foil charts on pages 13 and 14 are based upon the top foil riding over the
shank of a swage eye so it is 1

If you make any cuts in the foils be sure to
carefully clean all shavings from inside the
foils. Failure to deburr or clean the inside
of the foils may cause them to seize to the
connector during installation.
■ Roughing up Top Foil for Trim Cap
Rough up the top
a file or sandpaper.
■ Deburr the Foil
After cutting foil, clean all shavings from inside the
foil. Failure to deburr or clean the inside of the foil
may cause it to seize to a connector when it is being
installed.
■ Cutting and Drilling Bottom Foil
Consult the chart on page 13 to see if you need to
shorten the special bottom foil. If you do, use a hacksaw
to shorten the special bottom foil by 5" (127 mm). Make
sure you cut the end nearest the existing holes. Deburr
the foil after cutting.
Tip: there are two dimples in the bottom foil. The upper dimple is a
guide for cutting the foil. Wrap tape evenly around the foil so the top
edge of the tape runs through the center of the upper dimple. Line the
hacksaw blade up with this edge of the tape. The side of the blade
facing the lower part of the foil should run through the center of the
dimple.
Drill a hole using a
in the foil as a guide. The center of the dimple will be
