you may be able to take the magnets out of the metal rail, but the polarity of the magnets make it unlikely that tools will stay on the line of the magnet if its holding to 'ground' on both sides.
I'm not all that versed in magnetics, but I know on the ones I have the magnetic fields interfere with each other due to proximity, wrenches will slide if not held in place if you get the magnets too close or change the polarity,
The magnets seem to be glued pretty securely into the rails, and it doesn't seem like I'll be able to get them out without damaging the magnets.
I stopped by HF today and purchased a couple sets of the rectangular magnets. They stick to the rails very well and none of the wrenches are sliding off... although there are a couple of places on the rail where the wrenches don't seem to stick as strongly, but I'm able to avoid those areas.
The reason I don't want to bolt them into place is because I want to have the flexibility to move the rails around as needed.
into the North Georgia mountains to a little town called Talking Rock and picked it up. The town was holding a fall festival and we had a great time there in addition to meeting a fellow Marine who built this thing and no longer has a need for it. Life is good. Heres the listing:
