The clamps are more of a toggle then I had hoped for but I still think they will be useful for me. They are also higher then I would like but again there are work around to be had so all is good.
I built some added platforms for my Shaper Origin workstation using the same Rockler t-track that has sort of become my de-facto standard. Here are a couple of pictures showing the clamps on my platforms.
This second shot shows the workaround I mentioned.
Not going to be for everyone at that price point but for me it adds some more options that will be useful for my work flow.
