4 Pack House Floor Jack Hand Jacks 5 to 8.5in Adjustable - Heavy Duty

Our review of the 4 Pack House Floor Jack hand jacks finds them best suited for homeowners and contractors who need sturdy, temporary support under floors, staircases, decks or roof beams. The single biggest reason to buy is the combination of a 5 - 8.5in adjustment range with a 6,000 lb per unit capacity, which delivers heavy-duty holding power in tight spaces where conventional jacks or posts are impractical. The set of four simplifies leveling and multi-point support jobs and installs by one person without special tools.

Key Features

• Adjustment Range: The 5 - 8.5in telescoping range lets you fine tune height for leveling or temporary support in constrained spaces.
• High Load Capacity: Each unit is rated to support up to 6,000 lb (3 tons), providing strong point support for joists, beams and floor sections.
• HeavyDuty Construction: Thickened threaded post and bottom tube offer greater strength and durability for repeated use on building projects.
• Corrosion Resistance: Painted and galvanized surfaces protect the steel rods from rust, making them suitable for construction environments.
• Simple Installation: Rotate the top plate to the desired height and tighten the locating nut with a wrench for fast, singleperson setup.
• Compact Footprint: The 4 x 4in base plate and 3.2 x 3.2in top plate concentrate support where space is limited.

Who It's For

This pack is ideal for DIYers, remodelers and small contractors who need temporary adjustable support for flooring repairs, stair or porch stabilization, and deck or beam leveling. The individual 6,000 lb capacity and compact plates make these jacks useful in crawlspaces and tight work areas where conventional screw jacks or shoring equipment would be cumbersome.

Those needing longterm permanent supports or engineered shoring for structural alterations should consult a structural engineer and consider permanent posts or certified shoring systems instead, as these jacks are designed and marketed for temporary support and leveling tasks.
