About this item

  • 【Lightweight Yet Heavy-Duty PP Material】Crafted from premium composite PP material, each base weighs only 0.6 lbs—far than traditional concrete bases. It offers excellent corrosion resistance, oxidation resistance, and UV protection, making it ideal for long-term outdoor use. The lightweight design simplifies transportation and installation, significantly reducing labor costs and enabling rapid setup for terraces, walkways, and sheds.
  • 【Flexible Height Adjustment for Uneven Ground】Easily level floor joists with threaded height adjustment ranging from 2-3/8" to 5-1/2" (Model A) or 0.6" to 0.8" (Model B). This system lifts joists off the ground to prevent moisture damage and erosion, extend the lifespan of wooden decks, reduce maintenance costs, promote rapid drainage, and even create valuable under-deck storage space.
  • 【Exceptional Load-Bearing Capacity】Engineered for strength and stability, this deck support base holds up to 4600 lbs at its lowest height and still supports 2200 lbs at maximum extension. Whether for residential or light commercial applications, it ensures a secure, sag-free foundation that performs reliably under heavy loads.
  • 【Tool-Free Installation & Secure Fixation】No additional tools required—simply insert screws through the pre-drilled holes on the top plate to fasten the base to joists. The smart anti-slip and anti-tilt design prevents bending, swinging, or shifting. Build a solid, level deck foundation without excavation, mess, or curing time.
  • 【Versatile Application Across Outdoor Projects】Ideal for multi-layer terraces, walkways, sheds, plastic wood joists, stone bases, engineered grid floors, and greenhouse foundations. Compatible with support beams up to 3" thick, with recommended center spacing of 12"-20". A perfect concrete-free alternative for DIYers and professionals seeking quick, clean, and adjustable floor leveling solutions.

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
