QuadLock magnet holder adapter

Of course, I bought a cover from QuadLock that already has magnets installed. But it was not usable on the holder I was using. I came up with an idea and made a magnet adapter.I used 4 pieces of 10x2mm magnets.To get the best out of them you have to reverse the polarity of the magnets. It is best to put the magnets directly on the holder, but my other advice is to have the two opposite ones facing the other way.
