Corbin Russwin ML2030 NSA Privacy, Bedroom or Bathroom Mortise Lock, NS Lever, A Rose

The Corbin Russwin ML2030 NSA is a Grade 1 privacy mortise lock from the ML2000 series for bedroom and bathroom function in commercial and institutional settings. If you've been searching "ml2030" looking for this lock -the ML2030 is the privacy function (ANSI F19) in the ML2000 family. NSA identifies the trim: N is the Newport lever, S is the sectional escutcheon format, and A is the A rose trim configuration. This is the non-keyed version -no cylinder, no key slot on the outside.

ANSI F19 Privacy Function: How It Works at the Door

ANSI F19 is the privacy/bedroom/bathroom function. The outside lever retracts the latch normally when the deadbolt is not engaged. From inside, a thumbturn throws the deadbolt -when the deadbolt is extended, the outside lever becomes rigid and won't retract the latch. The door is secured.

From inside, the inside lever is always free. Turning it does three things simultaneously: retracts the latchbolt, retracts the deadbolt, and unlocks the outside grip -all in one motion. That single-action release means anyone inside can exit immediately without first turning the thumbturn to retract the deadbolt and then turning the lever. That simultaneous retraction is required behavior for life-safety compliance on egress doors.

From outside, the deadbolt can't be retracted by the outside lever. Access from outside requires either a key (on keyed versions) or the emergency release tool -a small, thin tool inserted into a release hole on the outside escutcheon that mechanically retracts the deadbolt from outside without a key.

The Emergency Release Tool: What the Thimble Wrench Is

If you arrived on this page searching "thimble wrench" -you're looking for the emergency outside release tool for the ML2030 privacy function. The outside escutcheon has a pinhole opening designed for a narrow release tool (sometimes called a thimble wrench or privacy spline tool) that a staff member inserts from outside to retract the deadbolt when someone inside is incapacitated or unable to unlock the door themselves. Contact American Locksets to confirm the correct emergency release tool number for the ML2030 LFIC or standard cylinder configuration.

ML2030 vs Other ML2000 Functions

The ML2030 is one of several ML2000 series functions. The ML2010 is passage -both levers always free, no locking. The ML2057 is storeroom -outside lever always rigid, key only from outside. The ML2030 privacy sits between passage and storeroom: normally both sides are free, but the inside user can lock the outside lever with the thumbturn when privacy is needed. Healthcare exam rooms, restrooms, hotel guest rooms, and private offices are the standard applications.
