Finjak™ – Tool-Free Center Fin Installation for Sliding Fin Boxes

$31.50
Color:

Change and adjust your center fin in seconds—no screwdriver, loose screw or separate fin plate required.

Finjak is a tool-free mounting system that makes fitting and adjusting center surfboard fins faster and easier.

Choose Finjak if you want:

  • Tool-free installation for a center fin

  • Quick forward or backward fin-position adjustments

  • One compact fitting instead of a traditional screw and plate

  • A convenient solution for longboards, mid-lengths and single-fin boards

  • Less loose hardware to carry or misplace

  • A genuine USA-made Finjak supplied by Eveley Surf

Compatible with: Center fins fitted to a standard sliding center fin box.

Fin position can noticeably change how a board performs. Move the fin forward for a looser, more responsive feel, or move it back for greater hold, stability and noseriding control. Finjak makes these adjustments easy at home, in the car park or between surfs.
