Product Description
The Sargent 8241-LNJ-03 is a 8200 Series Classroom Security mortise lock in Bright Brass (US3/605). Lockdown capable — can be locked from inside without opening the door.

Pro-Tip from Our Locksmiths: On high-security jobs, pair this with a Sargent Signature Series cylinder for restricted keyway control. The tolerances on Sargent cylinders are tighter than most competitors.
