• Heavy Duty 66000 lbs Load Capacity ✅ Boasting an extraordinary 66,000-pound load rating, this Screw Jack Post Kit is a industrial-grade stabilization device built for permanent or semi-permanent installations. The house jack achieved through the use of ultra-high-strength, low-alloy steel. Every component—from the thick-walled, seamless outer tube to the precisely machined, coarse-pitch Acme screw thread—is designed to handle extreme compressive forces without buckling, bending, or thread failure.
• Screw Jack Post Kit：Joist Holder & Screw Jacks ✅ Adjustable Jack Post combines the precise adjustability of a screw jack with the secure, non-damaging grip of a dedicated joist holder. The integrated joist holder positively locks onto 4x4 inches lumber (joists, beams, or headers) with a wide, U-shaped saddle that prevents lateral slip or roll. The dual functionality means you can use it as a traditional adjustable column for post-to-beam support, or instantly convert it into a targeted lifting device for joists.
• 0-45° Swivel for Uneven Surfaces ✅ Thanks to shore jack industry-leading 0-45° swivel range on the pivoting plate, ensures full, planar contact with beams and joists that are out of level, warped, or intentionally pitched for drainage. The swivel mechanism employs a robust ball-and-socket design machined from solid steel, housed within a reinforced cup. House jack moves smoothly under load and locks into position as force is applied, distributing weight evenly across the entire plate surface.
• 4x4 Wood Post Compatibility (Actual 3.5"x3.5") ✅ The house floor jacks kit features a perfectly sized 4" x 4" receiver socket, allowing you to securely insert a standard pressure-treated 4x4 wood post to extend the jack's effective height far beyond its standard 10"-14" range. This design transforms it from a simple short-range jack into a customizable shoring post capable of reaching basement ceilings, supporting high deck beams, or creating multi-story temporary bracing.
• Multi-Purpose Jack Support ✅ Crawlspace Shoring & Basement Support: Permanently or temporarily support weakened floor systems, sagging girders. Precision Floor & Beam Leveling: Its screw-adjustment allows for meticulous, gradual lifting of settled floor joists or sagging support beams to restore level surfaces without sudden, damaging force. General Construction Bracing: Used as a sturdy, adjustable brace for forming work, concrete pier construction, or supporting temporary walls.
