srs,
The rods are the ends of a pair of scissors jacks I mounted under the table to use for brakes. At the time I thought I needed them. Since then, I've found that the table (at over 500 lbs) is almost impossible to move, even when I want to, much less when I don't, so I really don't need them.
However, I DO need some type of levellers since my floor is a little uneven. That is a project for a future day I guess...
