Frequently Asked Questions (FAQ)

What's so special about the WildCard Fin Adapter?
This is the only adapter available that uses patented technology that lets you use your two-tab fins with a one-tab fin box. Most customers use their FCS 1 type fins with our adapters on boards with Futures Fins System fin boxes.

Do you ship internationally?
Yes, we ship all over the world! Generally, orders are processed and shipped in 1-2 business days.

What do the Quad and 5-Fin adapter sets include?
The quad adapter set includes two ¾ inch fin adapters for the outer-side fin boxes (left and right) and two ½ inch fin adapters for the inner-side fin boxes.

The 5-Fin set includes two ¾ inch fin adapters for the outer-side fin boxes (left and right), two ½ inch fin adapters for the inner-side fin boxes, and one ½ inch fin adapter for the rear center fin box.

What are the WildCard Fin Adapters made out of?
The adapters are made from true carbon fiber composite construction for extreme strength and durability with minimal weight.

Do you have an FCS2 version of the Adapter?
Yes, we have developed an FCS2 version of the adapter which we will be releasing very soon. If you’d like updates regarding the release of our FCS2 version please subscribe to our mailing list.

Do you offer any type of guarantee?
Yes. We stand by our products and are stoked only when you are! You can read about our guarantee here.

Do the adapters have cant angle built-in?
Yes. The side adapter's unique geometry tilts (or cants) side fins with approx. 4-5 degrees of canted angle.

My fins fit really tight with the adapters. Why is this and what should I do?
Sometimes the fin tabs can be slightly larger than what is expected. This can happen with self-made two-tab fins or with two-tab fins manufactured by other brands which have looser tolerances than FCS brand fins.

To get around this issue, we include a special strip of sandpaper and directions for lightly sanding the fins tabs so that they fit with ease into the adapters.

If you’re still having issues after some light sanding, please email and we’ll take care of you!
