3" x 48" Extension

Greater Depth. Greater Elevation. Unlimited Possibilities.

Designed for our 3" × 79" extendable ground screw system, this 48" galvanized steel extension provides the flexibility to reach greater foundation depths, accommodate elevation changes, and overcome challenging terrain.

Whether you're extending below the frost line, elevating a cabin, or building docks and waterfront structures, our modular extension system allows installers to adapt foundation depth and height to meet the unique demands of each project.

The 48" length provides additional reach with fewer connections, making it a practical solution for deep installations and elevated foundations.

From steep hillsides and uneven properties to remote cabins and waterfront construction, our extendable foundation system delivers the versatility needed to tackle complex projects without relying on traditional concrete foundations or extensive excavation.
