2 Pcs Adjustable House Floor Jacks 18-36in - Heavy Duty Support

In this review of the 2 Pcs Adjustable House Floor Jacks the bottom line is simple: these are a practical, heavy duty option for temporary support and leveling in basements, porches and crawl spaces. The pair offers an advertised lift capacity up to 5,570 lbs and an adjustable range of roughly 18in to 35in, which makes them useful for short-term structural shimming or during repair work. The reviewer found them straightforward to set up and useful when a compact, galvanized support solution is needed.

Key Features

• Adjustable Height: The 18in to 35in range lets users fine tune support height for floors, beams and low-clearance areas.
• High Load Capacity: Each jack is rated to provide substantial lifting force, suitable for localized support and leveling under heavy loads.
• Galvanized Finish: The colored zinc surface helps resist corrosion, extending service life in damp basement environments.
• Solid Construction: Built from steel with plated components, the jacks feel sturdy and stable under compression.
• Simple Adjustment: Height is set using two bolts and a screw nut with a cross bolt for added fixation and safety.

Who It's For

These floor jacks are aimed at homeowners, contractors and DIYers who need a compact, temporary support solution for leveling floors, supporting joists or stabilizing sections of a porch or deck during repair. They work well where a short travel range and a durable, metal support post are required.

They are not intended as a permanent foundation replacement or for long-term structural work where engineered piers or full foundation repair would be appropriate; anyone needing certified permanent load-bearing solutions should consult a structural professional instead.
