what's the proper name given to those metal poles that builders use to
hold up ceilings and overhead beams while they work? They're
adjustable in length and have a centre threaded sleeve for fine
adjustment (can't find a single one on google). Thanks for any
help.



Acro prop?

We always called them acro jacks.
