Overview
A six-pack of adjustable galvanized steel posts for temporarily supporting floor beams and joists during leveling or repair, adjustable from about 11-3/5 inch to 16-1/10 inch.
Each post has a 5 inch square base plate and a 3 inch square top plate; the base stays put while the top plate swivels to the needed height, then a positioning nut locks it in place with a wrench. The listing rates the set at a combined 13,200 lbs, about 6 tons total.
- 6-pack of adjustable jack posts

- 5 inch square base plate, 3 inch square top plate
- Galvanized, zinc-plated steel with a one-year warranty
Who it's for
Fits anyone temporarily shoring up a sagging floor, porch, deck or crawl space during leveling or repair work. Not a permanent structural fix and not sized for gaps outside its roughly 11 to 16 inch range.
Pros and cons
- One person can install and adjust each post
- Zinc-plated steel resists corrosion
- Combined rating of 13,200 lbs, about 6 tons, across the set
- Fixed adjustment range of about 11 to 16 inch
- Built as temporary support, not a permanent fix
Performance notes
The base plate stays stationary while the top plate threads up or down; once it reaches the needed height, tightening the positioning nut with a wrench locks it under load. Zinc plating over steel guards against corrosion for as long as the posts stay in place.
