You are bidding on two (2) new Plugs to fit inside Futures Fin boxes. Please specify color during checkout: add a note.

*I also have fin box plugs to fit the FCS II style of fins available - see my other listings.

*The new versions now shipping are the models with the two large cutouts; the old versions had multiple hex-shaped cut-outs.

These are designed and 3D printed in the USA, by Crooks USA - US patent applied for.. You won't find these anywhere else.

These fit securely inside the empty fin box using your existing set screws; they fit flush to reduce any drag and have a hole to aid in removal using the Futures hex key. 

Use two 1/2" tall Plugs for a 3-fin Thruster set-up or use one 1/2" tall Plug for a 4-fin Quad set-up.  

Single fin set-ups require at least two 3/4" tall plugs for the forward-most fin boxes, and possibly two 1/2" tall plugs; it will depend on how many fin boxes the board has. 

Please see the pictures on the difference between the 1/2" and 3/4" plugs.

Make sure to specify color and how tall the plugs are that you need in the "notes" section at check-out.
