    Locked When You Need It, Wobble When You Don’t

    Locked When You Need It, Wobble When You Don’t

    The Wobble-Fix Extension Bar gives you two modes in one extension so you can control the socket exactly how the job requires. Use Fix Mode to keep the socket rigid and perfectly in line for accurate torque transfer (and it won’t detach from the drive). Switch to Wobble Mode for up to 15° of pivot to reach fasteners in tight or awkward spots—while the locking mechanism helps prevent accidental mode changes during use. Built from premium chrome vanadium steel with a mirror-polished chrome finish for strength, durability, and corrosion resistance.

    How Wobble-Fix Works

    • Fix Mode — holds the socket firmly in line for precise torque transmission; socket cannot be detached from the drive
    • Wobble Mode — allows up to 15° pivot for better access around obstructions and in tight spaces

    Key Features

    • Dual-function design: rigid or wobble operation
    • Locking mechanism helps prevent unintentional mode change and helps prevent socket release
    • 250mm reach for deeper access
    • Chrome vanadium construction for durability
    • Mirror-polished finish for easy cleaning and corrosion resistance

    Where It Helps Most

    • Reaching recessed fasteners without losing socket control
    • Working around frame rails, brackets, hoses, and wiring where a straight shot isn’t possible
    • High-torque situations where you want the confidence of a locked connection
