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.
Famous quotes containing the word wrench:
“That is what we must make people feel... the catch in the throat, the wrench to steady the nerves, the determination to carry on.”
—John Dos Passos (1896–1970)
