FCS Longboard Box Adapter

I’d been trying to find a trailing nubster fin to use on my sled for a while but couldn’t get one to fit a centre box. Found the FCS insert online, tried it, worked a charm!

I know my board is old (3 years) but the fact I could retro fit FCS and make it work differently was a big win. Thanks FCS.

Have been using this product over the years. It is of good quality, fit for purpose & the only product still on the market.

Free at last from the single fin.

The best thing since sliced bread.

Don't hesitate get one.

Cool simple effective bit of kit!

I use the longboard box adapter with a nubster fin on my surfing SUP. My SUP has a quad fin setup, the adapter box and nubster fin adds a little lift in the tail down the line, and a little extra traction in tight turns. Great set up for a surfing SUP.
