Jack posts, Shoring Post, Lally column or Acrow prop. We have many names for these products. These posts are mostly used for shoring: temporary supports during building repair or alteration work, rather than scaffolding. A typical use is to support an existing horizontal beam while its original masonry supports are removed or repaired. When masonry itself is to be supported, holes are first knocked through the brickwork and a strong ‘needle’ or ‘strongboy’ is placed through the hole. A pair of props are then used, one under each end. Existing windows or doorways may also be supported directly, or via needles. As the plates on the end of the posts are typically small, they offer little sideways support. If there is any sideways force, props should be strutted or ‘laced’ with scaffolding poles.
