Performance Features
The Schlage Primus High Security cylinder is precision built to extremely close tolerances and the highest standards of quality. 
These “dual-locking” cylinders consist of two independent locking mechanisms, operated by a single specially designed 
Primus key. In addition to a standard 6 pin tumbler mechanism there is a locking sidebar which is independently controlled 
by a set of 5 fingerpins that interface with the side bitting on the patented Primus key.
Primus cylinders are offered in two different versions. The 20-500 High Security series which is UL Listed and the 20-700
Controlled Access series which offers the same key control protection when UL Listed cylinders are not necessary. Both series 
are fully compatible in application and can be combined into the same master key system, along with other Schlage 
conventional cylinders. For added flexibility, all Primus cylinders can be retrofitted into existing Schlage locks as well as 
many competitive products.
Primus Flexibility
Unlike many other brands of high security cylinders, Schlage can easily integrate Primus UL 437 Listed cylinders, Primus
Controlled Access cylinders, and Schlage conventional cylinders all into the same key system, and this happens with no 
adverse affects on keying capacity!
Primus keys will operate conventional cylinders but conventional keys will not operate Primus cylinders. You can secure 
exterior doors and sensitive areas with Primus cylinders and use conventional cylinders on the remaining doors. This cuts the 
cost of the overall job.
Security can be tailored to meet the exact needs of each door without sacrificing the convenience of having a single building 
master key.
