Hi. Steve, hope you are well and fine.
This may help you a bit.
I write-up screw type jacks or posts as “temporary supports.” So it doesn’t matter to me which end is up, it needs to come out after a permanent support is installed.

Aren’t these columns called lallys? Well, yes. I’ve heard that term used a lot. Lally columns or lolly columns are terms that are widely used in my area (Hudson Valley, NY) for any steel column. The terms also appear in various construction dictionaries. Originally a Lally Column was a proprietary name for the concrete filled steel column invented by John Lally. Many people feel that the term should only be spelled “Lally” and that it should only be applied to concrete filled steel columns. Perhaps they’re right. But, of course, language is fluid and in this case the popular use may have become the accepted use.
