Lock Operation Detailed
- Latchbolt by grip* either side, when deadbolt is retracted.

- Not available with M19S or M19SN.
The Corbin Russwin ML2020 DSR is a heavy-duty Grade 1 Privacy Bedroom or Bathroom mortise lockset on Dirke Lever x R Escutcheon (DSR) 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).
Privacy Bedroom Function -- What It Means
The Privacy Bedroom or Bathroom function (ANSI/BHMA F02) is a non-keyed lockset with a latchbolt and a deadbolt -- there is no cylinder. Latchbolt by grip either side when the deadbolt is retracted. Deadbolt by thumbturn grip inside or by emergency release tool outside. The catalog prints non-panic release and no simultaneous deadbolt and latch retraction. When lever handles are furnished, both outside and inside are locked when the deadbolt is projected. This function is not available with M19S or M19SN.
