Can wrench

A can wrench is a wrench made to open a telco can or demarcation point box. One end of the can wrench is a 7/16 of an inch hex socket, and the other end is 3/8 of an inch hex socket. They are often insulated against electric shock. The hex socket on each end is a thin wall thickness to allow the can wrench to be placed into the tight recessed access that often found on telco cans and demarc boxes.
