About this item

  • Universal U‑Head Fits 4x2, 4x4 & 4x6 Beams – The generously sized U‑shaped cradle automatically centers the beam without slipping or shimming. Whether you are leveling a sagging floor joist in a basement, supporting a deck beam, or reinforcing a porch, this jack delivers a snug, secure fit every time.
  • Smooth 16.5"-25.5" Micro‑Adjustment – Fine‑tune height with precision using the coarse‑thread screw mechanism. Unlike pin‑lock jacks limited to fixed positions, you can dial in exact lift increments – from 1/8 inch to several inches – for perfect floor leveling, foundation repair, or temporary shoring in low‑clearance areas.
  • Heavy‑Duty Steel Construction – 6,000 Lbs Capacity – Built from reinforced high‑gauge steel with a rust‑resistant coating. Each unit is load‑tested to support up to 6,000 pounds (3 tons), making it reliable for residential sagging joist repair, crawlspace leveling, and concrete beam stabilization. The welded telescoping tube eliminates weak connection points.
  • Versatile for Crawlspace, Basement, Deck & Garage – Use it as a temporary floor jack during foundation leveling, as a short telepost for basement support columns, or as a beam prop for deck renovation. Compact when retracted (fits tight crawlspaces) and easy to carry. Always install on solid bearing surfaces and consult local codes – for temporary or supplemental reinforcement only.
  • Effortless One-Person Installation – No need to call a contractor. Simply position the 3.5"x3.5" U-shaped head under your 4x4, 4x6, or 4x2 joist, turn the threaded screw to extend the jack from 13 to 17 inches, and tighten the locking mechanism. The telescoping design and large base plate provide stable support even on uneven crawlspace dirt or concrete.

FAQ

What types of products does FixTimber offer?

FixTimber offers supplies for repairing, reinforcing, sealing, weatherproofing, preparing, and finishing wood-frame homes. Our collections include wood repair compounds, adhesives, fasteners, structural hardware, exterior hardware, weatherproofing materials, finishing products, and repair tools.

How do I know whether a product is suitable for my project?

Review the product description, intended application, dimensions, materials, compatibility information, and installation requirements before ordering. If you are uncertain, contact us with details about your project and the product you are considering.

Are your products suitable for outdoor use?

Some products are designed for exterior applications, while others are intended only for indoor or protected areas. Check the individual product page for information about weather resistance, moisture exposure, temperature limits, and suitable surfaces.

Can I use these products for structural repairs?

Certain fasteners and connectors may be intended for structural applications, but suitability depends on the building design, load requirements, local codes, and installation method. Structural repairs should be evaluated and completed by a qualified professional when appropriate

Do products include installation instructions?

Instructions may be included with certain products or provided on their product pages. Instructions and accessories vary by manufacturer. Always follow the supplied directions and applicable safety requirements

How can I choose the correct size of hardware or fastener?

Measure the relevant lumber, opening, connection, or existing component carefully. Compare those measurements with the dimensions and specifications shown on the product page. Do not select structural hardware based on appearance alone.

Will product colors and wood finishes look exactly like the images?

Colors may appear different because of lighting, screen settings, wood species, surface preparation, and application method. Test stains, fillers, waxes, oils, and coatings on a small inconspicuous area before completing the entire project
