Surfboard Black Fin Plugs for Surfing Board and Softboard/Soft Top Surfboard Accessories（ 4 per Set）

I used these plugs to remove a few fins and reduce drag on a couple of my soft boards; they work great, stay locked, and I've reduced drag thanks to these. I recommend.

So far I am pleased with the product. It works as advertised, it's made of good strong, plastic material and it seems to keep screwed in well and tight.

Use them on my surface 10 foot board went from three fin to a single fin
