HYPERGIANT 4 Pack 11–16 Inch Adjustable Screw Jack Posts, 12,000 LB Max Load Capacity per Jack, Rust-Resistant House Jacks for Leveling, Crawlspace, Basement, Floor Joist and Beam Support — Open-Box, 12% Off

12,000 LB MAX LOAD CAPACITY PER JACK: Each individual orange screw jack post has a confirmed maximum load capacity of 12,000 lb for controlled support and fine-leveling applications. Match the jack, bearing surface, fasteners and placement plan to the actual structure and applicable local requirements.

ENGINEERED CONTACT SYSTEM: A square top plate, silver threaded steel screw, lock nut and eight-rib stamped base create a visible load path from beam to bearing surface. Four corner holes on each plate support project-specific fastening where appropriate.

PRECISE THREADED HEIGHT CONTROL: Insert the turning rod, rotate to raise or lower the top plate, seat the plate firmly and tighten the lock nut before loading. The screw mechanism is intended for controlled positioning and support setup, not hydraulic lifting.

THREE HEIGHT RANGES, TWO PACK SIZES: Choose 7–11, 11–16 or 16–21 inches after measuring the clear opening. Select 2 Pack for focused support points or 4 Pack when a basement, crawlspace or floor-framing project needs broader coverage.

RUST-RESISTANT ORANGE FINISH: The high-visibility finish is made for practical jobsite handling and helps resist rust in compatible support areas. These jacks suit crawl space, basement, floor joist and beam support plans when installed on solid, level contact surfaces.

HYPERGIANT adjustable screw jack posts are organized around dedicated working ranges instead of one oversized telescoping format. Select 7–11, 11–16, or 16–21 inches, then choose a 2- or 4-pack based on the required support locations. Each steel assembly combines a threaded post, lock nut, square top plate, and an 8-rib stamped base with four corner mounting holes. The removable turning bar is a shared adjustment tool; the 2 Pack includes one and the 4 Pack includes two. Install vertically on a flat, solid bearing surface, make controlled final contact, and lock the setting with a wrench. For temporary or supplemental support and fine leveling in crawlspaces, basements, floor joist and beam repair areas, decks, porches, sheds, and framing work. It is not a substitute for hydraulic lifting equipment or an engineered permanent structural column.
