Description:
This is an extensible shaft socket wrench for use in tight quarters -- the example given in the specifications is telephone switch gear. The end of the socket is smaller than the chamber directly above it. This is to deal with individual nuts in a "lock nut" type arrangement. The latch for the extensible shaft is an internal spring which can be depressed by a thumb nail.
