Primus cylinders are available to add patented* key control and varying degrees of geographical exclusivity to most Schlage 6- or 7-pin key systems, whether using Everest, Everest 29 or Classic Obverse keyways. In addition to a basic pin tumbler mechanism, Primus cylinders incorporate a patented* finger pin and sidebar design providing an independent, dual-locking mechanism in the cylinder that is highly pick-proof. Advanced features are optionally available as high-security UL 437 listed cylinders in Conventional (KIL) formats to provide proven resistance to drilling severe physical attacks.
*Patented key protection applies to Primus RP in Classic Obverse keyways and Primus XP in Classic, Everest and Everest 29 keyways.
