Socket extension, wobble, 3/8 inch drive, 150 mm, EX-C3150, TA.

A socket extension is a device that allows a socket wrench to reach into hard-to-access places. The socket extension fits between the ratchet and the socket to create a tool capable of reaching nuts and bolts in hard-to-reach locations. The wobble extension is designed to "wobble" when in contact with the socket providing enough flex to get a firm grip.
