About this item

  • DESIGNED EXCLUSIVELY FOR STANDARD 4*4 INCH SQUARE POST: Our jack posts adopt 4.01IN×4.01IN internal dimension design to solve the problem of wood expansion caused by thermal expansion and contraction and moisture absorption. Unlike other products that use external 4IN×4IN design (resulting in smaller internal size requiring secondary wood processing), our foundation jacks saves your precious construction time and high labor costs.
  • IDEAL FOR VARIOUS STRUCTURAL SUPPORT NEEDS: Jack support including crawlspace reinforcement, attic floor stabilization, house beam support, patio deck leveling, large equipment positioning, and stair platform reinforcement. Whether it's residential home improvement or commercial construction, this leveling jack provides reliable support.
  • ULTRA-HIGH LOAD-BEARING CAPACITY: Mini screw jacks boasts an impressive 10000lb load-bearing capacity, rigorously tested to withstand heavy structural loads without bending or deformation. rv Leveling jacks can solves the common problem of insufficient load capacity in some products, ensuring long-term stable support for your construction projects.
  • MADE WITH HIGH-QUALITY STEEL: Floor joist out support jacks crafted from premium SAE 1045 carbon steel featuring excellent tensile strength and durability.

Simply rotate the handle on the screw rod to adjust the height precisely after fixing the base and top square post. Note: The 4x4 post height range refers to the top of the post, not the base of the 4x4. The height at which wooden posts are cut needs to take into account the height enclosed by the 4x4 inch frame (excludes the jack's adjustable height).
  • TRIPLE SAFETY DESIGN: Utilizes AWS E8018 welding standard and argon arc welding process for strong, durable weld joints. The pole jack base is equipped with reinforcing ribs to prevent base deformation and sliding risks caused by uneven surfaces. A screw-jack limit observation window is also included to prevent risks from over-elevation, ensuring safe operation.
