Please watch Nishii's video explaining how to attach and remove FCSII fins.

[vimeo]https://vimeo.com/92307663[/vimeo] This video explains how to attach and remove the FCSII fins, which have been featured on LOST and Placebo surfboards since 2014. Watch this video before using FCSII fins for the first time to learn how to attach and remove them, along with tips and precautions. The pressure you apply when inserting the fins into the box may be a little daunting at first, as it's a strength you've never applied to a surfboard before. However, once you've experienced the right amount of pressure, you'll be able to attach and remove them without worry the next time. While not explained in this video, please remember that when removing the fins, instead of holding the base or entire fin, you should grasp the tip of the fin and push up to remove it using the leverage principle. This makes it surprisingly easy to do. The FCSII fins have an orange part inside the fin box that rotates, The fin is designed to stop when it catches on the fin body. Once you understand this structure, you will be able to better understand how much force to apply and in what direction. The old FCS plugs will be gone in a few years, so we encourage everyone to get an FCS II fin board. Free yourself from the time-consuming and tedious screw fin system you've been using until now! *
