Master Lock Built-In Combination Locker Lock

Master Lock built-in combination locks (such as the standard institutional locker locks like Model 1630 or 1670) are commonly installed on institutional, school, and gym lockers throughout North America, including Canada.

Founded in 1921 by locksmith and inventor Harry Soref in Milwaukee, Wisconsin, Master Lock invented the laminated padlock and grew to become one of the most recognizable security and lock brands globally.

Today, Master Lock is owned by Fortune Brands Innovations, Inc., a publicly traded home and security products company based in Deerfield, Illinois, United States. While early locks were predominantly manufactured in the United States, current manufacturing operations are distributed across facilities in the United States, Mexico, and China.
