The FinjakTool-Free surfboard fin installation device replaces the metal plate and screw of your single fin longboard, midlength, 2+1 surfboard or SUP.
 
Effortless to install, remove, or adjust your fin in seconds, the FinjakTool-Free is the perfect fin bolt replacement that every longboard, midlength & retro board rider needs to enhance your sessions and dial your fin and surfboard perfectly to your taste.
 
Designed for rear tab fins the fins we have in stock are front tab fins and although the finjak will still work with a front tab fins it does make it easier for them to be knocked loose whilst surfing.
