The Fin Box Lock attaches to longboards, SUPs, wave skis, windsurfers - anything with a sliding fin box. 2 nylon side keys fit into the grooves on the inside of the fin box. A centre key locks them in place. Finally a padlock connects the Fin Box Lock to a PVC-coated cable. The cable can be looped around a roof rack, or just shut into a car door with its running ball on the inside.

The Fin Box Kit includes:

  • a Fin Box Lock (3 blue glass-filled nylon keys)

  • a 1.8 metre, PVC-coated braided steel cable with nylon running ball

  • a 40 mm heavy duty brass padlock with 2 keys: if buying multiple locks, these are keyed identically

  • a Gumby Lock lanyard - to carry your car key in the surf

  • a Gumby Lock car sticker - to tell would-be thieves not to bother.

Perfect Fit

By: on 9 October 2017
The Gumby Lock is a perfect fit for my SUP and it's really quick to put on. I can just lock my board onto the roof rack and go for a coffee without having to worry about it being stolen. It's unbelievably good value and was delivered really quickly. Five stars.
