This 1-inch mortise cylinder meets ANSI A156.5 Grade 1 standards for heavy-duty commercial use. The brass body with satin chrome finish provides corrosion resistance in high-traffic door applications. It ships as a pair keyed alike with two keys per cylinder and includes a Yale 8 keyway. Rekeyable to original manufacturer systems for master-key integration.

Sustained Access Control Performance

The five-pin mechanism maintains consistent operation through repeated daily cycles without degradation. Grade 1 certification confirms the cylinder resists physical attack and meets cycle-test requirements for institutional environments. Keying alike simplifies key management across multiple doors while preserving individual rekeying capability. The included turn knob and dummy components support varied mounting configurations.

Environmental Compliance and Material Safety

Brass construction contains substances listed under California Proposition 65 for cancer and reproductive-harm awareness. The satin chrome finish reduces surface wear under constant handling and cleaning. No electronic components or power draw are present, eliminating thermal or acoustic concerns. Installation relies on standard mortise preparation without additional infrastructure.
