OCEANBROAD Surfboard Fin Thruster 3 Fins for FCS-Based Future-Based Fin Box with Screws Wax Comb Key

This worked great as a replacement for the side fins on my Great Lakes Woody SUP.

Busted my fins of my paddle board these fit perfectly with unscrewed the little Allan screw and they push right in

I did have to file/sand down on bump in the bottom of one fin to get it to fit flush, took 2 minutes.UPDATED...I just used them and they worked good. I'm not an expert, just intermediate and can't notice the difference between these and $100+ fins.For some reason I tried to remove the logo, to have all black fins, but was a mistake, for the area I sanded is now gray...but they still look descent and work fine...I like how they have flex, lets me push my limits and not worry about fin cuts as much.

Side fins fits perfect but middle one doesn’t fit, sad.

Replaced some subpar brittle fins off a fun board. They are in protected packaging, everything is there that you need. I didn’t use their tool or wax comb, to be honest, the comb is tiny and not sure who would use this over their normal comb, but I’m sure it works in a pinch. The important thing is the fins are well made and held up to a week of knocking around so far beautifully.

The fins on my surfboard broke and these were the perfect replacement. Easy to install and very sturdy.

they work fine for my amateur needs but, seem to vary in thickness at the base by a fraction resulting in a loose wobble.
