3" x 24" Extension

Adjustable Height. Versatile Foundations.

Designed for our 3" × 79" extendable ground screw system, this 24" galvanized steel extension provides additional height and flexibility for foundations requiring elevation adjustments, increased ground clearance, or customized structural support.

Whether you're elevating a cabin, compensating for changes in ground elevation, or building on challenging terrain, our modular extension system allows installers to achieve consistent foundation heights across uneven properties.

Extensions can be combined to accommodate varying elevations, providing a practical alternative to traditional concrete columns and extensive excavation.

From elevated decks and remote cabins to hillside construction, the 24" extension offers a versatile solution for projects requiring adaptable foundation heights and reliable steel support.
