Schlage commercial cylinders are ideal for a wide range of commercial applications, from airports, hospitals, universities and offices, to research laboratories, and government and military buildings. Since our cylinders can be used in a wide range of Schlage and competitors’ locks, you can pair the lock you need with the security level that fits your application.
Schlage’s high quality conventional cylinders provide the standard level of security and functionality for Schlage locks. The exclusive use of solid brass bar stock plugs and shells, phosphor bronze springs, nickel silver keys and bottom pins ensures long life and ease of operation. 6-pin Everest cylinders in C123 keyway with two patented keys are standard for stock. C145 is standard for new master key systems.
A conventional cylinder is one that requires some breakdown of the lock in order to be removed. These are the most commonly used cylinders. Because conventional cylinders are manufacturer-specific to the lock and lock type, they cannot be exchanged for another in most cases. However, conventional cylinders can be keyed alike or master keyed so that you can use just one key for multiple locks if needed. They are best suited for light commercial applications with a small number of users, such as retail stores and small offices, as well as residential applications that do not require frequent change of cylinders.
