Built from steel with a brushed chrome finish, it uses a 6-pin Schlage C-type cylinder and a 2.75-inch backset. The keyed-alike configuration allows a single key to operate multiple locksets across a facility, reducing key management complexity. This lockset is installed by locksmiths, general contractors, or maintenance technicians working on commercial or institutional interior door hardware. It meets ANSI\/BHMA A156.2 standards and carries a UL listing, making it appropriate for code-compliant door hardware installations.\u003c\/p\u003e\n\u003cp\u003eThis lockset is suited for classroom applications in schools, offices, and institutional facilities where a door must be locked from the hallway side without a key from the inside. The classroom function allows occupants to exit freely at all times while the exterior knob remains locked by default or on demand. The 2.75-inch backset fits standard door preparations found in most commercial interior doors. The brushed chrome finish is compatible with common commercial door hardware finishes and is appropriate for high-traffic environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eClassroom function: exterior knob locks without a key from the inside, free egress maintained at all times\u003c\/li\u003e\n  \u003cli\u003e6-pin Schlage C-type cylinder for enhanced pick resistance\u003c\/li\u003e\n  \u003cli\u003eKeyed-alike configuration simplifies key management across multiple doors\u003c\/li\u003e\n  \u003cli\u003eSteel construction with brushed chrome finish for durability in high-traffic settings\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI\/BHMA A156.2 Grade 2 standards and carries UL listing\u003c\/li\u003e\n  \u003cli\u003eFits doors up to 1.75 inches thick with a 2.75-inch backset\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for standard commercial interior doors up to 1.75 inches thick with a 2.75-inch backset preparation.
