Built to ANSI\/BHMA Grade 1 standards, it delivers heavy-duty cycle performance suited for high-traffic doors. The lock features the Rhodes lever design and is finished in Aged Bronze (643E), offering a traditional aesthetic that coordinates with commercial door hardware sets. The non-handed configuration means it installs on both left-hand and right-hand doors without modification, simplifying procurement and installation on mixed-swing openings.\u003c\/p\u003e\u003cp\u003eThis lock is intended for classroom security applications in schools, universities, government buildings, and similar institutional settings. The classroom function keeps the exterior lever locked by default, allowing egress from the interior at all times while restricting outside entry. A standard cylinder allows keyed entry from the exterior, which is the typical configuration requested by facility managers and security coordinators. Licensed locksmiths and commercial door hardware installers are the primary trades that specify and install this unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eANSI\/BHMA Grade 1 rating for heavy-duty, high-cycle commercial use\u003c\/li\u003e\n\u003cli\u003eClassroom lock function: exterior lever locked by default, free egress from interior\u003c\/li\u003e\n\u003cli\u003eRhodes lever trim for a traditional institutional aesthetic\u003c\/li\u003e\n\u003cli\u003eAged Bronze (643E) finish coordinates with complementary commercial hardware\u003c\/li\u003e\n\u003cli\u003eNon-handed design installs on left-hand or right-hand doors without modification\u003c\/li\u003e\n\u003cli\u003eStandard cylinder for keyed exterior access\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation commercial classroom lock compatible with standard ANSI prep doors in institutional and educational facilities.\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 ANSI door prep standards.
