【Superior Capacity & Range】 Engineered with power and precision, this support system boasts an extended height adjustment range from 55 inches (4.6 ft) to 99 inches (8.25 ft). It delivers exceptional load-bearing performance: supports up to 18,000 lbs per post at its minimum height (36,000 lbs total for the pair) and 9,100 lbs per post at full extension (18,200 lbs total), ensuring safety and stability for your most demanding tasks. 【Premium Build for Lasting Durability】 Crafted from high-grade steel and fortified with a protective anti-rust coating, these jack posts are built to withstand heavy loads and harsh job site conditions. This superior construction ensures maximum sturdiness, long-term reliability, and optimal performance even in damp environments like basements and crawlspaces. 【Engineered for Maximum Stability 】 Each heavy-duty jack post is built with a 4x4 inch (100x100 mm) integrated welded steel top/base plate. This critical design isn't an add-on—it's permanently fused to the column, creating a unified, ultra-rigid structure. The large surface area dramatically increases contact with the ground or floor, which effectively distributes extreme weight over a wider area, preventing sinking, shifting, or tilt. Whether placed on concrete, soil, or wooden subfloors. 【Versatile & Heavy-Duty Temporary Support】 These robust adjustable jack posts provide indispensable temporary shoring for diverse projects, from major renovations to essential repairs. Perfect for solving common structural issues such as leveling sagging floors, supporting basement or crawlspace beams, stabilizing roof framing, and reinforcing decks, porches, and stairs. Your go-to solution for reliable, on-demand structural support. 【Complete Jack Posts Kits 】 The package includes two fully assembled jack posts, two dedicated turning bars for jack height adjustment, and all required mounting hardware (lock pins, nuts, and pre-drilled base plates). Everything is designed for quick, tool-free adjustment and secure, hassle-free installation.
