VEVOR House Floor Jacks 4-Pack Telescoping Joist Jacks 11.6"–16" Galvanized, 10,000 lb Total Capacity

These adjustable post-style jacks are built from Q235 steel and feature a threaded screw column and integrated welded base plate for quick setup and reliable temporary bracing. Each jack extends between 11.6 and 16 inches, supports up to 2,500 lbs, and is operated by turning the hex nut with a wrench to fine-tune height. They are intended for non-permanent support tasks such as propping a sagging floor, stabilizing a cabinet, or holding up a frame during repairs.

How do these jacks adjust and lock at the right height?

Height is set by rotating the welded screw collar with a wrench to move the inner telescoping tube up or down. The threaded nut gives small, controllable increments for precise leveling; for safety and ease, adjust to the desired position before placing heavy loads on the post.

• Telescoping screw design for smooth incremental height changes
• 11.6" to 16" (29.46–40.64 cm) working range per jack
• Use a wrench on the hex nut to lock position
• Best to set height prior to loading heavy weight

What load capacity and construction features matter for safety?

Each VEVOR jack is fabricated from durable Q235 steel and zinc-galvanized to resist corrosion. With a rated capacity of 2,500 lbs per jack and a combined support rating of 10,000 lbs, they are intended to handle substantial temporary loads when used on a stable surface and with correct placement.

• Q235 steel body for structural strength
• Galvanized finish for rust resistance
• Integrated welded base plate reduces assembly steps
• Rated per-jack and combined capacities clearly specified

Where should I use these joist jacks and where should I avoid them?

These jacks are designed for temporary support and leveling tasks in residential or light-commercial settings: under sagging floor joists, beneath cabinets and bed frames, and to hold door frames during repair work. They are not engineered as permanent structural supports or for lifting vehicles and should not replace professional shoring for major structural interventions.

• Suitable: propping floors, supporting cabinetry, bracing frames
• Not suitable: permanent structural use or heavy mechanical lifting
• Do not overload beyond 2,500 lbs per jack
• Place on solid, level surfaces and use even load distribution

How easy is installation and what tools do I need?

Installation is straightforward: position the welded base plate, raise the inner tube to the approximate height, then fine-tune by turning the hex nut with a wrench. Because the base plate is welded to the pipe, there’s no additional hardware to assemble, which speeds setup and reduces error.

• No separate base-to-pipe fasteners needed thanks to welded plate
• Adjust final height with a standard wrench
• Quick to position for temporary jobs or short-term projects
• Recommended: check level and distribute load across all four jacks

Who is this for: tradespeople, DIY homeowners, and contractors who need a dependable set of temporary support posts for lifting, leveling, or stabilizing building elements during repairs or renovations. If you require portable, adjustable, steel jacks that set up quickly and carry heavy temporary loads—VEVOR’s 4-pack offers an accessible, corrosion-resistant option.
