Schlage Locks

Schlange manufactures entryway products including doorknobs, door hinges, knockers and viewers, handle sets, electronic keypad locks, built-in alarm locks, and more. They are located in Olathe, Kansas and have offices worldwide. Schlange began with a simple door lock that was able to turn lights off and on, invented by Walter Schlage in 1909. By 1920, Schlage left his job with Western Electric and opened his own business. Schlage was established as a company by 1923 and in 1974, the company was acquired by Ingersoll Rand becoming part of the Ingersoll Rand Door Hardware Group. Still a well-known name in entryway hardware, Schlage represents quality and security for many homeowners and business.
