1/2-Inch Drive Extension Bar, 380mm Chrome Vanadium Steel

Overview

This 380mm extension bar is engineered to extend socket access in confined spaces and deep-set fasteners. The polished chrome-vanadium construction delivers corrosion resistance and durability across thousands of cycles. Whether you're working on engine bays, suspension components, or industrial assemblies, this extension bridges the gap between your ratchet and socket where space is limited.
