That spongy floor and the hairline crack above the doorframe whisper the same message: your beam is tired. Ignore it and joists twist, doors stick, and weekend budgets disappear into contractor quotes.

Imagine walking across a rock-solid floor, walls that stay straight, and a storage space you actually trust with holiday décor. One quick upgrade turns the wobble into a memory and hands the savings back to you.

Meet the Bostome Adjustable Steel Floor Jack Post. Built from Q235 structural steel and rated to 24,700 lb, this Jack Post slides under 4×4 wood beams to lock them in place. Spin the precision screw—13.2"–18.7" range—no extra tools, no extra hands. The 4"×6" plates spread load evenly, while the compact, handle-off design tucks onto a shelf until the next project. Basements, crawlspaces, deck rebuilds: done in minutes, not days.

  • Pro-level reinforcement without the pro bill
  • Adjustable height for tight, accurate fit
  • Detachable handle for easy storage

Add the Bostome Adjustable Steel Floor support to cart now and shore up your home—no contractors required.
