JET 3/8-Inch Drive 3-Inch Locking Socket Extension Bar (671947 / SLEX3L) | Used, Great Condition | High-Torsion Chrome Alloy Locking Extension Rod

Lock your sockets firmly in place and prevent dropped hardware in deep, cramped work zones. Upgrade your socket drive setup with this used JET 3/8" Drive 3" Locking Socket Extension.

When working in cramped engine bays, machinery housings, or deep recess channels, standard extension ball detents can slip, leaving your socket stuck behind on the fastener head. The JET 671947 (SLEX3L) 3/8" Drive 3" Locking Extension eliminates this hassle with a positive slide-locking collar mechanism that firmly locks attached sockets onto the drive anvil until manually disengaged.

This item is in excellent, fully functional used condition. The quick-release locking collar slides smoothly and holds sockets with a tight, secure grip. The male drive anvil and internal female square drive remain square with clean drive engagement. Forged from high-grade Chrome Vanadium steel with a protective finish, it exhibits minor cosmetic shop wear—including light surface scuffs and faint tool-box marks from normal shop use—with zero rounding, burring, or mechanical flaws.

Key Features & Benefits
