Cutting Top Track To Length
Use a file to deburr the cut.
Slightly round off the corners of the track
that will slide against the mast so it will not
catch when sliding the track up the mast.
If your track length is shown in the chart
on page 5, use a hacksaw to cut a special
length of top track from a 6'8 3 /
4
" (2.05 m)
track.
Round your track length to the nearest
1 /
2
"
(10 mm) and extrapolate to determine the
top track length.
Drill two 13 /
64
" (5.5 mm) holes in the cut end
of the top track centered at 5 /
16
" (8 mm) and
1 1 /
16
" (27 mm) from the track end.
Slip the rubber end stop over the cut end
of the top track.
Before You Start...will mounting slugs and cars fit?
NOTE: You will cut the bottom track in Step 10.
Clear of Trysail Track?
To make sure the track will tighten against
mast, put a mounting slug in the groove, a
track section on the mast and use a screw
to test.
Also, make sure mounting screw is long
enough for your mast groove.
Check to make sure the 2 5 /
8
" (67 mm) long
connector slug will fit in the feeder opening.
If necessary, use a file to make the feeder
opening longer.
Use a halyard to run the 2
5 /
8
" (67 mm) long
connector slug up the entire mast. Use a
retrieval line. If it jams, clean the groove.
If there is prebend in the mast, you may
need to straighten it out somewhat to
install the battcar system.
Warning!
Screws must have three (3)or
more threads engaged to hold track to mast.
Make sure screw makes three (3) full 360°
rotations after threads engage in slug.
Cars are 2 1 /
4
" (57 mm) wide. Make sure they
do not hit trysail track or other obstruction
up the entire spar. Tracks often converge
above the spreaders.
