3" x 79" Extendable Screw

Engineered for Greater Depth. Built for Alaska.

Designed for Alaska’s challenging soil conditions and deep frost zones, our extendable ground screw system provides the flexibility to achieve greater foundation depths while maintaining structural stability.

The 3" × 79" hot-dip galvanized ground screw features a modular design compatible with 24" and 48" extensions, allowing installers to reach deeper, more stable soil and accommodate site-specific frost depths.

This versatility makes it an ideal foundation solution for cabins, decks, elevated structures, and remote construction projects.

Using the same proven modular foundation principles found in professional ground screw systems worldwide, our extendable screws offer a practical solution for challenging terrain, variable soil conditions, and frost-sensitive environments.

Greater Depth. Greater Versatility. Engineered for Alaska.

Extensions sold separately. Required depth and load capacity depend on site-specific soil conditions and engineering requirements.
