The Corbin Russwin ML2069 PSM is a heavy-duty Grade 1 Institutional Privacy mortise lockset on Princeton Lever x M Escutcheon (PSM) trim. It is built on the ML2000 Series platform and is certified to A156.13 Series 1000, Operational and Security Grade 1.
Institutional Privacy Function -- What It Means
The Institutional Privacy function (ANSI/BHMA F26) locks the outside grip with a thumbturn inside. Latchbolt by grip either side except when the outside is locked by that thumbturn. Operating the inside grip or closing the door unlocks the outside grip. A key outside retracts the latch at all times, even if the thumbturn is held in the locked position. An auxiliary latch deadlocks the latchbolt when the door is closed. The catalog prints that this function is not available with M19S, M19N, M19V, M19SN, or M19VN indicators.
Institutional Grade Features & Benefits
- Inside thumbturn lock: a thumbturn inside locks the outside grip. This is not a deadbolt function.
