It features the 06 lever trim on the N escutcheon and is finished in Aged Bronze (643E). The classroom function keeps the outside lever locked by default, allowing egress from the inside at all times while restricting entry from the exterior without a key. This makes it a standard choice for K-12 and higher-education facilities where controlled access and life-safety egress must coexist. Licensed locksmiths and institutional hardware specialists are the primary installers.\u003c\/p\u003e\u003cp\u003eThis lock is suited for interior corridor doors in classroom, laboratory, and office environments where a dedicated classroom security function is required. The FSIC less-core configuration gives facilities management flexibility to specify their own interchangeable core from a compatible keying system during construction or retrofit. The field-reversible handing means the lock body can be oriented for left-hand or right-hand doors without ordering a separate unit, reducing lead-time risk on multi-door projects.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eGrade 1 ANSI\/BHMA heavy-duty mortise lock construction for institutional and commercial doors\u003c\/li\u003e\n\u003cli\u003eClassroom security function: outside lever locked by default, free egress from inside at all times\u003c\/li\u003e\n\u003cli\u003eFSIC less-core design accepts full-size interchangeable cores specified by the facility\u003c\/li\u003e\n\u003cli\u003e06 lever style on N escutcheon for a low-profile, institutional appearance\u003c\/li\u003e\n\u003cli\u003eAged Bronze (643E) finish for consistent trim coordination\u003c\/li\u003e\n\u003cli\u003eField reversible handing without disassembly of the lock body\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation mortise lock for commercial and institutional doors requiring a Grade 1 classroom function with FSIC cylinder preparation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed locksmith or qualified commercial door hardware technician familiar with mortise lock preparation standards. Confirm door thickness and backset dimensions before installation and verify the mortise pocket dimensions match the lock body.
