When your board arrives from the factory, there
is already a screw plate and screw in your center
fin box. Unscrew the screw from the fin plate and
slide the fin plate all the way to the front of
the fin box (towards the front of the board). Set
the screw aside for a minute.
On the center fin, there is a metal peg on the
back of the fin base. When putting the center fin
into the fin box, drop that peg thru the wider opening
at the center of the fin box and down into the track.
The peg will slide down the track. It's pretty tight
sometimes, so we use a rubber mallet to tap, tap,
tap it back into position so the fin is roughly
centered within the larger fin box.
Rotate the front of the fin base down and line
up the hole at the top of the fin base with the
hole in the screw plate. Drop the screw that you
set aside into the base of the fin and thread it
into the screw plate. Sometimes if a really tight
fitting fin and you'll just barely be able to get
the screw threaded into the plate. Don't worry about
it. As long as you can get it threaded, the leverage
of the fin plate can suck the fin base down flush.
Note if you are having trouble getting your center
fin to fit in the fin box you can lightly sand the
edges of your fin's base to get it to fit in.
