Schlage
From Wikipedia, the free encyclopedia
Schlage is a lock manufacturer founded in 1920 by Walter Schlage in San Francisco. Schlage is one of the most popular brands of consumer and commercial locks in the United States. Schlage also produces a high-security key and cylinder line that is compatible with its standard line called Primus. In addition to the usual grooves cut into the key, there is side milling which, when the Primus key is inserted into the Primus cylinder, causes side pins to rotate a certain amount to allow the cylinder to open. A Primus key can be cut to open a standard Schlage cylinder, but a standard Schlage key cannot open a Primus cylinder.
In 1974, Schlage became part of the Ingersoll Rand company.
