FCSII (FCS2) Fin Box Installation Kit

Greenlight developed this fool-proof FCS II (FCS2) fin box install kit with the DIY home surfboard builder in mind. No need for an expensive professional fin box install kit costing twice as much as this one when you're only making a few boards a year... plus it's quite probable you haven't used a trim router before and we know it's intimidating so we made this install method very safe to use and simple.

The install method is based around precise plunge routing with special depth collars for each step of the route. Watch the FCS II fin box install video below to see how easy we made installing fin boxes.

We even throw in a sheet of foam to practice routing multiple times before putting the router to your fresh shape!

Install Kit Includes:

FCS II Base Router Jig

Aluminum Router Base Plate (designed for Greenlight Router or Makita RT0701C)

Depth Stop Collar 

1 1/2" long router bit

Fin Cant Angle Jig

Sheet of Practice Foam

Order this fin box installation kit with or without a trim router and install dummy fins are recommended to set the fin cant correctly (or you can use real fins)


Ask a Question
  • Hi If I was to make a fcs 2 jig would I have to put the the right and left lines on it to get the correct fine placement or could I just use the mid point on the jig for the side fines

    When installing FCS2 fin boxes you can use the centerline of the install router jig and measure 1/8" more to account for left or right fin placement. So 1 1/4" in from the rail you'd place the shaper's dot at 1 3/8"

  • Will these be coming back into stock any time soon guys?

    Greenlight FCS II (FCS2) Fin Box Installation Kit will become available for sale by March 2021.
