I have FACTORY / FCS X-2 plugs, how are they installed?

CLICK HERE for the FCS X-2 Fin Plug Install Manual

More detailed install info below:

NOTE: For EPS boards use Slow Hardener Epoxy or set the plugs with 2 resin pours to reduce exotherm and prevent melting the foam. See Step 4. 


1. FCS X-2 and FACTORY plugs are installed after the seal coat. After installation and the resin has cured, you sand them down flush with the board while sanding the bottom.


2. Once you have the quickset jigs laid out on the board (lined up with your shapers dots) you will use a FCS Hole Saw bit or FACTORY Holesaw to make your holes for the plugs. Drill the hole 5/8" deep and pull the foam out with needle nose pliers or dig out with a flathead screwdriver. 


3. We suggest using either FCS dummy jigs or a set of fins to set the plugs with the correct spacing as well as adjust the fin cant angle. Lightly screw the plugs onto the dummy jig tabs. If using fin keep the plugs loose on the fin tabs so you can push them down to where the "nubs" on the plugs touch the seal coat.


4. Polyester boards: Mix 1 oz of resin per plug. (6 oz total for a tri-fin, 8 oz total for a quad). 

    EPS boards:  Use Slow Cure epoxy resin, or if using Fast cure, mix 1/2 oz resin per plug. Pour resin in the holes about 1/3rd deep to set the plugs in. You will come back and fill the rest of the perimeter in another step. Doing 2 separate pours will prevent the EPS foam from potentially melting from epoxy exotherm. 


5. Polyester Board: Pour about 1/2 oz of mixed resin into the holes. 

    EPS Board: Pour about 1/2 oz mixed resin into the holes.


6. Place the plugs in the holes with the dummy jig or fins to ensure proper alignment. Set the fin cant to the desired angle and hold in place with tape. Here is an illustration of taping the fins in place (these are glass ons but same taping methods apply to FCS fin plugs)



7. Polyester Boards: Using a small cup (dixie cups work great) carefully pour resin around the perimeter of the plug so it runs into the drilled hole. Be careful not to over fill! Fill just under the lip of the plug and jig. 

   EPS Boards: Let the first pour cure for about 2 hours then mix another 1/2 oz epoxy resin per plug and top off.


Once the resin cures remove the jigs and sand the plugs down until they are flush with the board.
