Tolsen Impact Extension Bar | 1/2″ | 125 mm is a robust extension lead designed to extend the reach of your impact wrench or ratchet. This 125 mm bar provides additional length, allowing access to bolts and fasteners in tighter, hard-to-reach spaces where standard tools fall short. It is suited for use with 1/2″ drive sockets, making it a versatile addition to a mechanic’s or DIY enthusiast’s toolkit.
This extension bar works by connecting between your impact tool and the socket, transferring the torque while increasing your working radius. The “Impact” in its name suggests it is built to endure the stresses of impact tools, which typically generate higher torque than regular hand tools.
When selecting an extension bar, it is critical to match the drive size and length with your existing tools to ensure compatibility and safety. This listing represents the Tolsen brand unit with SKU BB-400126. Confirm your tool’s drive size is 1/2 inch and that a 125 mm extension suits your working conditions before purchasing.
