Jack post
A jack post is a steel post used in the construction trades for temporary support of ceilings, walls and trenches (shoring). They are designed to be able to mechanically telescope to about twice their shortest length in order to span a wide variety of spaces. Most examples use removable pins for coarse adjustment and a jack screw for fine adjustments, but many variations exist.
