## Questions & Answers

**Q: I have a progessive sup looks like opening is 10.5 x 1.25 in abs .  how is it installed and will it fit?**
A: It installs exactly how a normal single fin would install to any single fin box, and your FCS center fin will go in it as it would into a pair of FCS fin tabs (using fcs hex screws to secure). I will admit, it is a tight fit for FCS Brand fins to get into,  I sanded the two tabs a little bit on a cheap FCS Center fin to make it a little easier to get into the adapter. True Ames fins fit in a little easier. However the adapter fits perfectly into any Single fin box (U.S. or Aussie). Worth the purchase price to experiment with

**Q: Is this product durable enough to suppot a home made foil mast?**
A: Sorry I am not sure what kind of loads a mast puts on a fin box but if other fin boxes can handle it, so can ours.

**Q: can you tell me the width of the opening of the fin box?**
A: The slot that accepts the base of the fin is 1/4 inch wide. The center slot that accepts the  metal pin is 9/16 inch. Not sure if that is what you mean by "opening". The fin box is an industry standard for almost all fins designed for a single fin surfboard.

**Q: Is it installed similiar to a future center fin box, before laminating or after hot coat?**
A: I installed mine after the hot coat.

This fin and box was installed on a 8’ SUP and works great. My grandsons are having a ball. Very solid once installed and the board runs true. Very good product and a lot cheaper than I thought they would be
