76.1mm x 4.8CHS x 3000mm Extension and bolts to Suit with External Drive Lugs

The 76.1mm x 4.8mm CHS x 3000mm Extension gives you extra reach on deep foundation projects. Standard pile lengths sometimes cannot reach the required load-bearing soil. Workers build this extension from high-quality Circular Hollow Section (CHS) steel for vertical reach and structural integrity.

Key Features

• Precision Engineering: Made from 76.1mm OD steel with a 4.8mm wall thickness, resisting buckling and lateral shifts.
• External Drive Lugs: Robust external lugs transmit torque efficiently from the hydraulic drive head for smooth installation.
• Complete Connection Kit: Each extension arrives ready to go, with the high-tensile bolts you need to secure the connection.
• Durable Finish: Built to withstand corrosive soil, giving you a long-term foundation solution for decks, solar arrays, and modular buildings.
