These are the clamping elements:
Ah those things - thanks.
I"ve been babbling on another thread about the MFTs and clamps ... I'm impressed with the "system-ness" ( sorry ) of the Festool bench, clamps, etc - but it seems a bit locked in and "average" in quality compare to the rest of the Festool kit.
It's pretty obvious that some of the clamps are made by Bessey - but I don't really know who's behind the clamping elements.
