Hey Jim,
I checked my original comment but I find the attribution of “with it” was meaning the “Any Surface Leveling System”. Maybe you are reading too fast sometimes

BTW, mine did not have threaded inserts as you suggested might be there. I don’t know if that’s a change in manufacturing, but my QCW has drilled & tapped holes in the bottom of the foot blocks.
As far as I understood you did not order the Any Surface Leveling System, so as I tried to explain above, you did not get the threaded inserts, just one big hole in each QCW foot block with no thread in it, is this true? This is what was reported too in this thread.
I feel a little bit uncomfortable as I rarely bring myself into a situation where I do not provide my sources, but because of our planned (and unfortunately now delayed) move everything is full of cardboard boxes with our packed things, partially stacked up to the ceiling, so I will provide a photography of the threaded insert that is part of Any Surface Leveling System later! So please everone pardon me, it’s not my style to not provide a picture or a link!
