...as a plug that can go into the side fin boxes on a longboard so you can convert from a 3 fin setup to a single fin? I swear I think I've seen guys out with setups like that but I couldn't find anything searching online. I probably just suck at searching tho
btw the side biters on my log are futures....dunno if you needed to know that but there it is just in case
