Tie Wire as used in the electrical construction industry is sold in coils of 12 pounds and generally made from 16 gauge black soft annealed wire. It is popular because it is both pliable and difficult to break. This property of being easy to bend makes it ideal for hanging troffers from black iron, holding victor splits in place for temporary wiring and other uses. It is often ordered in units of Stones or as a Stone of Tie Wire because of the old British measurement of a STONE. A STONE is 14 American Pounds, over time the trade has shrunk it to 12 pounds.
