Master Lock

 In 1919, Harry Soref designed a padlock with laminated layers of steel like those used in the production of bank vault doors and battleships. In 1921 Soref founded Master Lock with the help of two friends and a humble, 5 man work force. Since then Master Lock has come to be recognized around the world as the authentic, enduring name in padlocks and security products. They continue to earn and maintain the trust of their customers by delivering on their promise of strength and quality and by continually setting new standards for lock design, application and performance. Master Lock is currently the world's largest importer of padlocks, combination locks and related security products.
