You're welcome.
The FS-rapid clamps come in handy every once in a while (not as much as I thought they would when I got them). When you use them you should be carefull not to overthighten them (which is easy and will cause the rail to bend a bit).
But they are ideal if you have to cut a cabinet or box that is already assembled (or stuff that is otherwise hard to clamp with the regular clamps).
I have also used them for repeated cuts aswell, which I thought would be the primary use for them, but I don't like them very much for that purpose, and if the cut isn't square, tightening the clamps will cause the rail to move of the mark.
Up until a few years ago festool sold profiles that were specially meant for the fs-rapid clamps so you could use them as a bar clamp.
