### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Initial snags overcome.
  

*by P***O on Reviewed in the United Kingdom on 1 June 2019*

So I ordered this to fit an fcs fun box fir my custom 9’6” long board.On arrival I went to put the metal “ fin bars “ into the fin box on board.  Didn’t happen. After lots of repeated trying and nearly giving up  it eventually took the bars.  Felt like they needed to forge a groove through the fin box before it eventually took them and now they go in every time.The kit itself is sturdy and to be honest if u didn’t have a set of bolt croppers handy you aren’t going to be able to steal a board without ripping the fin box out which I can’t see the average opportunist doing as would be more time consuming than stealing the car ! I will certainly use it regularly.  I did change the padlock to a combination lock just because I don’t want yet more keys to lose. If u have a board you treasure and want to leave it on the roof whilst you go to get a few beers in Tesco on the way home from a good surf, get one.  :-)

    Disappointed
  

*by J***E on Reviewed in the United Kingdom on 16 December 2021*

The main product doesn’t fit particularly well inside the fin boxes of any of my boards - it’s quite the struggle to remove it. More disappointing still is the padlock. What a load of cheap rubbish! Used twice and no longer works. Spoke to Northcore and they couldn’t give a hoot!

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars

It does everything it says on the box. Exactly what I needed. Brilliant
