Adjustable Jack Post Basement Support: Steel Column for Foundation, Floor Repair, Home & Workshop | FJB100, FJB150

For residential basements, home renovation zones, commercial crawl spaces, and building foundation repair projects, this adjustable jack post series provides a practical and organized structural reinforcement solution. Fabricated from high-strength structural steel treated with a corrosion-resistant finish, these heavy-duty columns are engineered to lift or support sagging beams, subfloors, and overhead joists without buckling under load. The telescoping design features a precision screw mechanism that allows users to perform fine-tuned height adjustments and achieve an accurate, level alignment manually. Complete with wide structural steel plates at both the top and base to distribute weight evenly, this robust support post matrix ensures a stable foundation across damp or subterranean environments.
