SATA GL12906 3/8" Drive Locking Extension 3"

Specifications: 3" length, 3/8" drive compatibility, chrome vanadium steel (Cr-V) construction, chrome-plated finish for corrosion resistance, knurled grip for better handling, and a secure locking mechanism to hold sockets firmly in place. It’s designed for high-torque tasks while remaining compact for tight spaces.

The extension features a locking collar that secures the socket onto the extension. To lock, align the socket with the extension, push together until the locking mechanism engages, and gently tug to confirm a solid hold before applying torque.

It is designed to work with all 3/8" drive ratchets and sockets. The secure locking feature ensures compatibility is maintained during use across typical 3/8" tools.

Use it to reach fasteners in tight or recessed areas, such as automotive undercarriage work, engine bays, or machinery maintenance where a standard ratchet can’t reach without additional length.

To install: insert the 3/8" drive into the ratchet, place the socket onto the extension, and engage the locking mechanism. To remove: disengage the lock, then slide the socket off and detach the extension from the ratchet. Always inspect the connection before applying torque.

Wipe it clean with a dry or lightly damp cloth. Avoid prolonged exposure to harsh chemicals. Periodically inspect the locking mechanism and knurled grip for wear, and ensure markings remain readable for quick identification.

Yes. Do not use the extension as a hammer or leverage tool, avoid overtightening beyond what the socket and fastener require, keep hands and clothing clear of moving parts, and ensure the socket is fully seated and locked before applying torque.

Compared to similar 3/8" locking extensions, this 3" model offers compact reach with a robust Cr-V construction and knurled grip for precise handling. For longer reach, consider the 4" model, and for different handling or length preferences, the 6" variants provide extended reach while maintaining locking reliability.
