Standard Cylinders
Schlage locks are provided with cylinders precision built to
®
extremely close tolerances and the highest standards of accuracy.
Using only 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.
Primus High Security Cylinders
®
Primus high security cylinders are available to add patented key
control and varying degrees of geographical exclusivity to most
Schlage 6-pin key systems, whether Everest or Classic keyways.
In addition to a conventional pin tumbler mechanism, Primus
cylinders incorporate a patented finger pin and sidebar design
providing a "dual-locking" cylinder that is virtually pick-proof.
Resistance to drilling and other physical attack is optional by
specifying 20-500 Series UL437 Listed cylinders.
Primus Lockout Cylinders
®
For doors where it is frequently desirable to disable all keys
from operating the lock temporarily, use lockout cylinders.
The special lockout key can be removed while the plug is turned
to the 11 o'clock position, preventing all normal operating keys,
including master keys, from fully entering the cylinder.
Suggested applications for lockout cylinders include laboratories,
dark rooms, clean rooms, and exterior doors to dormitories.
Schlage will not master key lockout cylinders.
