Lock Operation Detailed
- Latchbolt by grip either side, unless outside grip is locked by toggle-action stop or by projection of deadbolt.
- Deadbolt thrown or retracted by key outside or by thumbturn grip inside.
- Latchbolt and deadbolt retracted by key when outside grip is locked by toggle-action stop.
- Inside grip simultaneously retracts latchbolt and deadbolt; outside grip remains locked.

The Corbin Russwin ML2067 DSP is a heavy-duty Grade 1 Apartment or Dormitory mortise lockset on Dirke Lever x P Escutcheon (DSP) trim. It is built on the ML2000 Series platform and is certified to A156.13 Series 1000, Operational and Security Grade 1.
Helpful hint: Dirke levers are handed. The upwards curve points to the hinges -- that is the lever handing. A lever pointing right (the factory DSM photo) is RH or RHR. A lever pointing left is LH or LHR. Choose LH or RH on this listing. The lock case can still be field-reversed for swing (RH to RHR, LH to LHR).
Apartment Function -- What It Means
The Apartment or Dormitory function (ANSI/BHMA F20) locks the outside grip by a toggle-action stop or by projection of the deadbolt. Latchbolt by grip either side unless the outside is locked that way. Deadbolt thrown or retracted by key outside or by thumbturn grip inside. Latchbolt and deadbolt retracted by key when the outside grip is locked by the toggle-action stop. The inside grip simultaneously retracts latchbolt and deadbolt; the outside grip remains locked. The outside grip is unlocked by the toggle-action stop. An auxiliary latch deadlocks the latchbolt. An indicator, when specified, shows deadbolt position only.
Institutional Grade Features & Benefits
- Toggle-action stop: a mechanical stop in the inside faceplate locks or unlocks the outside grip. This is not a key or thumbturn lock.
- Deadbolt indicator only: when an indicator is specified, it shows deadbolt position only.
- Inside retracts both: the inside grip retracts the latchbolt and the deadbolt together.
- Outside stays locked: retracting the deadbolt from inside does not unlock the outside grip.
- Grade 1 certified: Certified A156.13 Series 1000, Operational and Security Grade 1.
- Lever handing: Specify LH or RH. The lever is not field-reversible. The lock case can still be re-handed for swing (LH to LHR, RH to RHR). The upwards curve points to the hinges.
- Fire listing: UL/cUL-UL10C Positive Pressure
- Warranty: Ten-year mechanical warranty.
