Fin Box Lock

This lock fits my board's fin box just fine. Easy to install and remove (when not locked), and it looks like it would not be easy to remove when locked without causing come damage to the board. A really determined thief who didn't care about taking a small chunk out of the board around the fin box would be able to remove the lock, but it will certainly deter most crooks looking for an easy score. I'm glad I have it. Now I don't have to worry about running into a shop to use the restroom, or have a quick lunch while my board is on the roof rack.

This is easy to take off and on before paddle boarding, but impossible to take off when my masterlock is through the whole. It's the only lock I know of for paddle boards and without, I would not be able to store my paddle board anywhere.

Works well, pricey for two simple pieces of aluminium.

Way overpriced for what it is but works, I had to enlarge the lock holes to fit my python cable lock

This is excellent for locking a Stan Up Paddleboard. Fits right in the fit slot and locks in place. One you put a padlock through the hole the FinLock is not coming out until you remove the padlock. Add a steel cable to attach the paddelboard to something immovable and you are all set.

We installed with the suggested lock. You can move the Fin Lock to the middle of the fin channel, tilt it at the center hole and pop it out. Not secure. Only looks secure. This is with the board fins off, when you stack boards for transport.

Secured my SUP on the roof top with this fin box lock and a fairly thin 3/16 cable lock to run it through the roof rack. Provides peace of mind against a snatch and grab but a pair of bolt cutters could clip the cable I think. At least it would slow down bad actors. We combined with ties down straps that have steel cables running through them and between the two it would take a determined thief. The fun box mock is a little fiddley and kind of awkward on the roof cause I’m short but it’s not hard to use…just takes a bit of practice. I would recommend.

I live in a second-floor apartment and was not using my board as much as I would have liked because I didn't feel like hauling it up and down the stairs. This was a simple cost-effective solution to securely lock my board on the ground floor. It takes no time at all to get the lock off or on, and no matter how much you try to wiggle it out, it stays in the finbox. Highly recommend!
