2 PCS Adjustable House Floor Jacks for Leveling - Telescoping Support

In this review the 2 PCS Adjustable House Floor Jacks are evaluated as a straightforward, heavy-duty solution for temporary support and leveling during construction or repair work. The set is best for homeowners, contractors, or remodelers who need a compact, mechanical option to stabilize floor joists, porches, decks, crawl spaces or stairs while making repairs. The single biggest reason to buy is the combination of a usable adjustment range and high per-jack load capacity, which makes these jacks suitable for many common structural support tasks.

Key Features

• Auxiliary support: Provides temporary or additional support for weak floors, crawl spaces and joists so repairs and leveling can proceed safely.
• Adjustable range: Telescoping design adjusts from 11.8 in to 16 in, offering flexibility for small elevation changes without needing shims.
• High load capacity: Each jack is rated between roughly 6,860 lb and 9,920 lb (3 to 4.5 ton), suitable for many residential and light commercial support tasks.
• Durable construction: Heavy-duty steel with a painted finish resists wear on job sites and is built to last through repeated use.
• Simple installation: Keep the base plate stationary and rotate the top plate to adjust height, then secure with a spanner and the M22 locking nut for a quick setup.
• Safety locking: M22 screw thread and locking pins add stability and reduce the likelihood of unintentional collapse during temporary support.

Who It's For

These jacks are aimed at homeowners tackling floor leveling or joist repair, small contractors needing portable temporary supports, and anyone working in crawl spaces, porches, decks or stair framing who needs a mechanical, non-hydraulic solution. The compact size and telescoping adjustment make them handy for confined areas.

Those who need micrometer-like adjustments under heavy load or who prefer hydraulic jacks for rapid lifting should look elsewhere; customers warned that adjustment can be difficult under load, so these are best used as temporary supports applied and adjusted with the load removed or supported by other means.

Pros & Cons

Pros

• Solid build quality and painted steel finish give a sturdy, long-lasting feel.
• High per-jack capacity makes them versatile for many residential support needs.
• Simple mechanical adjustment and M22 locking hardware are familiar and reliable on site.

Cons

• Adjustment under load can be problematic, so users should avoid trying to rotate the top plate while supporting full load.
• Telescoping range is limited to short lifts (11.8 in to 16 in), so they are not suitable for large height corrections.

Our Verdict

Frequently Asked Questions

Can these jacks be adjusted while under load?
Adjusting under full load is not recommended; customers report difficulty turning the threaded top when supporting weight, so support the load externally before final adjustment.

What is the usable lift range?
The telescoping height range is 11.8 in to 16 in, intended for short height corrections and temporary support tasks.

Are these jacks suitable for outdoor use?
The painted steel finish resists wear and is fine for typical outdoor tasks like porches or decks, but regular inspection for corrosion is advised in wet environments.
