Snap-On GL122GS is a 16-inch locking-button extension designed for a 3/4-inch drive, providing extended reach for sockets while secure engagement prevents accidental disconnection during use. This model corresponds to Snap-On's GL122 locking extension, a 16" extension commonly listed in catalogs for 3/4" drive systems, enabling compatibility with standard Snap-On ratchets and sockets. The combination of length, drive size, and a locking connection makes it well-suited for accessing recessed fasteners in tight or cramped spaces where a longer reach is needed.
