Installing a center fin in your longboard or SUP is extremely easy and fast. It takes less than a minute, and you don’t even need any tools!
The installation process is the same whether you have a longboard or SUP… I will be using my longboard in this example.
Our longboard fins come with a “no-tool” screw, so you can hand tighten the screw. If you are using a different fin/screw, you might need a screwdriver to tighten the screw. All the other steps in this guide should be the same, no matter what fin/screw/board you are using.
Installing Your Longboard/SUP Fin
1. Lay the screw plate into fin box.
Carefully slide the screw plate into the fin box, and move it towards the front of your board. You can use a pen or screwdriver to move the plate, because your finger probably won’t fit in the box.
2. Insert fin into box.
The back of your longboard fin has a pin in it. You insert this part into the middle of the fin box, and then slide the fin back (with the front of the fin still lifted).
Find your desired position for the fin. Position is all preference… the farther back the fin, the more stable it will be. The farther forward the fin, the more maneuverable it will be.
Once your fin is in position, you can push the front of the fin down into the box. If it fits too tight, you can remove the fin and gently sand the sides of the base.
3. Tighten the screw.
Line up the screw plate with the end of your fin, so the screw can thread in. You’ll want to use a pen or screwdriver to move the plate around.
If you have a “no-tool” screw (like our longboard fins come with) you can just hand-tighten the screw.
If you have the classic longboard screw, you’ll need a screwdriver to tighten it.
