Master Lock

About Master Lock

Master Lock has been America's leading security company since 1921, when founder Harry Soref revolutionized the lock industry with affordable yet durable security solutions.

Founded by Russian immigrant and locksmith-inventor Harry Soref, the company was created to bridge the gap between expensive but strong locks and cheap but easily broken alternatives.

In 1924, Soref received a patent for the revolutionary laminated steel padlock using the same construction method as bank vaults and battleships.

The company became the largest padlock manufacturer in the US by 1950 and introduced their first gun lock (Model 90) in 1971, establishing their presence in the firearms security market.

Today, Master Lock continues to provide trusted security solutions for gun owners, hunters, law enforcement, and shooting sports enthusiasts nationwide.
