got the big one. was clearanced out. only one they had. They have legs about 2 3/4 inches once they are in the holes. I bought a huge piece of plexiglass last year and couldn't find anything that would work for legs. I have not cut that yet. I think I will just put it in the same area as the extension table when I have large pieces. I am thinking of blocks. I have some baby ones that I maybe can use. double face tape or something.
