9-Piece Locking Quick Release Extension Bar Set | 1/2 Drawer EVA Foam

    DETAILS

    Reach recessed fasteners and keep sockets securely attached with the BoxoUSA 9-Piece Locking Socket Extension Bar Set with Quick Release. Featuring 1/4", 3/8", and 1/2" drives, each in 12", 18", and 20" lengths, this set provides access to deep engine bays, machinery, and other confined work areas.

    The locking mechanism retains the socket during use, helping prevent accidental separation when withdrawing tools from hard-to-reach locations. Quick-release controls allow fast socket changes, while knurled grip sections improve handling when connecting, removing, or turning extensions by hand.

    Made from chrome vanadium steel for durability and strength, each extension features a mirror chrome finish that resists corrosion and cleans easily after use.

    All nine extensions are organized in a precision CNC-cut 1/2 drawer EVA foam insert. Dedicated compartments keep each extension securely positioned, while the two-tone foam makes missing tools easy to spot. Chemical-resistant EVA foam provides durable storage in demanding workshop environments.

        KEY FEATURES

        • Three Drive Sizes, Multiple Lengths: 1/4", 3/8" and 1/2" drive extensions in varied lengths provide reach and ratchet/socket compatibility for automotive repair, equipment service and general maintenance.
        • Locking Socket Retention: Holds the socket securely on the extension, preventing separation and dropped sockets when withdrawing from recessed or obstructed locations.
        • Quick-Release Control: Disengages the lock for fast, controlled socket removal and changes without tools or excessive force.
        • Chrome Vanadium Steel: Provides strength and durability under repeated torque loading in shop use.
        • Mirror Chrome Finish: Resists corrosion and wipes clean of oil, grease and debris after use.
        • Knurled Grip Sections: Improve handling control when connecting, removing or hand-spinning extensions, including with oily hands.
        • CNC-Cut 2-Tone EVA Foam: A 1/2 drawer insert for the 26" BoxoUSA system holds each extension in a dedicated compartment. Two-tone foam provides immediate missing-tool detection, and the chemical-resistant material holds up to shop fluids.
