Description
Product Overview
The Yarlung 4 pack adjustable support jacks are engineered for demanding floor leveling and temporary support tasks. Constructed from high‑grade steel with a corrosion‑resistant coating, each jack offers a solid base plate measuring 4 inches wide and a top plate of 3.25 inches, delivering a stable platform for heavy loads. With a load capacity of 4,500 pounds, the jacks can safely bear equipment, furniture, or structural components while you perform adjustments or repairs.
Designed with a smooth‑turn screw mechanism, the jacks provide a height range from 4.2 to 7.4 inches, allowing precise leveling across uneven surfaces. The ergonomic design lets you keep the base plate stationary while swiveling the top plate to the required height, then secure it with a pipe wrench. This simple operation reduces setup time and minimizes the risk of slippage during use.
Dimensions of each unit are compact at 4 × 4 × 7.4 inches and weigh only 1.4 pounds, making them easy to transport and store. The universal fit design ensures compatibility with a wide variety of floor types, including wood, concrete, and composite decking, providing versatile support for both residential and commercial applications.
Usage
These jacks excel in scenarios where floor integrity is compromised, such as weak wooden subfloors, aging decks, or temporary scaffolding setups. Contractors often employ them to level floor joists before installing permanent supports, while DIY homeowners use them to stabilize a porch or crawl space while performing repairs. The compact size allows placement in tight spaces, making them ideal for under‑carriage adjustments or RV step stabilization.
In addition to structural leveling, the jacks serve as reliable supports for heavy equipment during maintenance. For example, they can hold a workbench, a large appliance, or a piece of machinery while you access the underside for inspection or repair. Their ability to bear up to 4,500 lb ensures safety even when supporting dense loads.
Because the jacks are made from steel with a rust‑resistant finish, they perform well in outdoor environments, such as deck foundations or outdoor workshops. The easy pipe‑wrench adjustment means you can quickly raise or lower the support without specialized tools, enabling efficient workflow on job sites where time is critical.
