Adjustable House Floor Jacks 4 PCS - Telescoping Post Jacks

In this review the Adjustable House Floor Jacks are examined for homeowners and contractors who need temporary support when leveling or stabilizing floor beams and joists. The set of four telescoping screw jacks covers an adjustment range from 11 in to 16.5 in and delivers a high capacity of 11,000 lbs per jack, making the main reason to buy their strength and adjustability for heavy repair work. The reviewer found them straightforward to use with the included wrench and appreciated the mixed finishes that help resist corrosion in typical indoor and semi-exposed applications.

Key Features

• High load capacity: Each jack supports up to 11,000 lbs so the full set can bear a combined 44,000 lbs for heavy duty temporary support.
• Adjustable height: The 11 in to 16.5 in telescoping range provides fine leveling control for floor beams, porches, decks and crawl spaces.
• Durable construction: Steel construction with a galvanized upper finish and black oxide lower finish improves corrosion resistance and longevity.
• Compact plates: The 4.1 in square base and 3.5 in square top plates provide stable contact points for joists and beams during adjustments.
• Easy to operate: A simple wrench is included so adjustments are made by turning the height nut without additional tools.

Who It's For

These jacks are aimed at homeowners, contractors and DIYers who need a reliable temporary support solution for leveling floor joists, shoring up porches or stabilizing stair framing during repairs. Their heavy per-jack capacity and modest height range make them suitable where substantial vertical support is needed but clearance is limited.

They are not intended as permanent foundation posts or for use on soft, uneven ground without adequate bearing pads; users who need long-term adjustable foundation posts or very tall shoring solutions should look for purpose-built permanent systems or longer telescoping models.

Pros & Cons

Pros

• High rated capacity per jack gives confidence when supporting heavy beams.
• Simple height adjustment with included wrench makes setup fast on site.
• Corrosion resistant finishes on upper and lower sections extend usable life in semi-exposed locations.
• Compact top and base plates fit tight framing conditions and provide stable contact.

Cons

• Limited height range of 11 in to 16.5 in may not suit jobs requiring greater reach or permanent support.
• Designed for stable, hard, level ground when used as an RV step brace or exterior stabilizer, so additional footing may be necessary outdoors.
