This adjustable floor jack is designed to provide temporary, reliable support in construction and renovation projects. It combines a heavy-duty steel construction with corrosion-resistant coating to withstand demanding environments, whether you are leveling a new floor, stabilizing a staircase, or supporting a beam while you work. The height can be set anywhere from roughly 11.8 in. up to 16 in. and each unit carries a substantial load range from about 6,600 to 11,000 lbs. making it suitable for mid to heavy applications. The base and top plates are dimensioned for stable contact, with a threaded M22 connection and a 12.4 in. adjustable lever to dial in the precise height you need. Operation is straightforward: keep the base plate steady, rotate the top plate to the desired height, use the swivel lever to fine-tune, and secure the height by tightening the M22 nut with a wrench. For best results, set the pole height before loading to avoid difficult adjustments once under load. Use cases span stairways, flooring projects, porches, roof beams, decks, or any tight space where extra support or stabilization is required. Installation is practical for a solo worker, with slim profile components that fit through narrow work areas, and the system can be adjusted with common hand tools. Safety screws provide additional engagement during use, and routine checks help ensure consistent performance.
