The Sargent RX-10XG37-LL-12V-KD is a Grade 1 classroom function cylindrical lock built for heavy-duty commercial and institutional openings where security and reliable access control matter.

The 12V wiring supports low-voltage monitoring, while the LA keyway comes keyed random with two keys for immediate use in schools, offices, and other secured facilities.
