Critical points of entry and highly sensitive areas need extra protection. Here, Schlage cylinders with added Primus features provide a "next level" upgrade of security that works within your existing Schlage key system. Even non-restricted key systems no longer under patent protection can regain top levels of administrative and physical security anywhere Primus cylinders are applied.
Primus keys and cylinders take different paths to patent protection depending on the keyway family. The Classic Obverse family, which includes the famous Schlage C keyway, carries a patent to 2029 as a Primus RP (Raised Pin) key design. The Everest 29 family in Primus XP differs in that it is the Everest 29 patent that carries to the year 2029 protecting designs for all Everest 29 products including the Primus XP keys and cylinders.
Patented against unauthorized key duplication
All Primus keys are tightly controlled and have a unique, factory-milled side bitting design that is geographically defined and can be made exclusive to the user at a local or even national level
Optional, high-security UL 437 listed cylinders feature hardened steel drill pins and are confirmed under UL testing protocols as pick-resistant, drill-resistant and capable of withstanding extreme physical attacks
