No. The Baldwin 6001 mortise lock body is a 2-3/4 inch backset lock, so the cylinder and knob spindle centers sit 2-3/4 inches from the door edge. On a door already prepped for the 2-3/8 inch backset (the other common residential backset), the trim holes will not line up and the mortise pocket depth will be short. Check the existing prep before you order; if the pocket was cut for a 2-3/4 backset mortise lock, this drops straight in.

The 6001 lock body is built for doors 1-3/4 inches and over, which covers standard 1-3/4 inch entry doors and the thicker solid doors common on older or custom homes. It is not the part for a 1-3/8 inch interior door.

Handing matters. This is the right hand version of the Baldwin 6001 entry/apartment mortise lock body. Stand outside the door: if the hinges are on your right and the door swings away from you, that is right hand. Order the wrong hand and the latch bevel faces the wrong way and will not latch into the strike.

It has a 1 inch throw deadbolt with saw-proof inserts, on top of the knob-operated latch. A full 1 inch throw is what you want on an apartment or exterior entry door, since it reaches deep into the frame strike rather than just the jamb face. Make sure your strike pocket is mortised deep enough to take the full inch.

Just the lock body. The 6001 is the mortise case that goes into the door pocket, knob by knob. You still need to order the trim (knobs, roses or escutcheons) and the cylinder to finish the opening. Match the trim to the same 2-3/4 inch backset and to the finish you want visible.

No, and this is where buyers get it wrong. The 6001 is a residential Estate Series lock. For a commercial opening that needs a Grade 1 mortise lock, look at the Cal-Royal NM8050 heavy duty Grade 1 office/entrance mortise lockset, or the Cal-Royal NM8070 for classroom function, both listed for 1-3/4 inch doors. The Corbin Russwin ML2003 is another Grade 1 classroom mortise lockset in the ML2000 Series.

The Baldwin 6001 is an Entrance/Apartment function mortise lock body with a 2-3/4 inch backset, built for residential use. Where an apartment corridor door needs a commercial lock instead, the Sargent 7925 is a Grade 1 mortise lock in the 7900 Series with Corridor/Dormitory function, rose trim and a single cylinder deadbolt. The Cal-Royal NM8050 is another route: a Grade 1 Entrance/Office mortise lockset with an auxiliary deadlatch for 1-3/4 inch doors. Both are lever or commercial-trim products rather than the knob-by-knob Estate Series look the 6001 carries.

The 6001 is an Entry function lock body, so it is keyed rather than privacy. For bed and bath openings, the Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset for doors 1-3/4 to 2 inches thick, which matches the 6001 backset. The Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with a deadbolt for 1-3/4 inch doors.

No. The Baldwin 6001 is a working Entry/Apartment mortise lock body with a 1 inch throw deadbolt and saw-proof inserts. The Emtek 3102 Memphis is a dummy function mortise entrance lockset, as are the Emtek 3019 Brisbane, 3104 Hamilton and 3106 Manhattan. Dummy trim is fixed and does not latch or lock, so it suits an inactive leaf rather than the operating door the 6001 serves.

The Baldwin 6001 is built for doors 1-3/4 inch and over. For thinner stock, the Marks USA 21AC is an entrance double cylinder Unilock ornamental iron mortise lock with a round knob for 1 inch doors, and the Marks USA 22AC is an entrance double cylinder ornamental iron mortise lock with a round knob, also for 1 inch doors. Both keep entrance function and knob operation on narrow ornamental iron doors.

Entry/apartment function means the outside knob is locked or unlocked by key, the inside knob always retracts the latch for free egress, and the deadbolt is thrown separately. That is the arrangement a landlord wants on a unit door: the tenant can always get out, and the outside stays secured by key.

The Baldwin 6001 is key only, no electronics. For keypad access in a mortise prep, the Alarm Lock DL3500CR Trilogy is a Grade 1 electronic mortise lock holding 300 user codes, and the DL2700CR Trilogy T2 is the weatherproof version; both are listed for 1-5/8 to 1-7/8 inch doors, so confirm your door thickness, because they will not take the thicker doors the 6001 handles. The Schlage LE Series LEBMB-ADD is a mobile-enabled mortise lock with apartment function for 1-3/4 inch doors.

The 6001 is a knob by knob case in the Estate Series on a 2-3/4 inch backset, so the trim you pair with it has to be Estate Series knob trim cut for the 2-3/4 backset. Lever trim or trim built for a different backset will not line up with the spindle and cylinder holes in this case.

The Baldwin 6001 is a knob by knob Entry/Apartment mortise lock body that combines latch and a 1 inch throw deadbolt with saw-proof inserts in one case. The Sargent 4874 is a double cylinder mortise deadbolt in the 4870 Series with a 2-3/4 inch backset, so it provides bolt only and no knob or latch operation. The Kaba Ilco 185 Series is likewise a deadbolt function mortise lock, supplied with no handing.

The Baldwin 6001 uses a 2-3/4 inch backset and is an Entry function lock. For a non-keyed opening at the same backset, the Hager 3810S is a Grade 1 passage mortise lock with a rose and a 2-3/4 inch backset, and the Hager 3810E is the same passage lock with an escutcheon; both cover doors 1-3/4 to 2-1/2 inches thick. The Hager 3850E is a non-keyed office function mortise lock with lever and escutcheon at the same 2-3/4 inch backset.

The 6001 is an Entry/Apartment residential lock. For storeroom and service doors in the same building, the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with the Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors. The interchangeable core option matters where a facility already keys to a single core system.

The 6001 is a mechanical Entry/Apartment mortise lock with a 1 inch throw deadbolt. For electronic access on a similar opening, the Schlage Electronics LEBMB-ADD is a Grade 2 mobile-enabled mortise lock in the LE Series with push button and LED, covering privacy, office and apartment functions on 1-3/4 inch doors with a 3 hour fire rating. The Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock for wide stile doors, and the Alarm Lock DL2700CR is a Grade 1 electronic mortise lock with classroom function and weatherproof design for doors 1-5/8 to 1-7/8 inches thick.

No. The Sargent 130KB is a standard duty mortise thumbturn in the 8200 Series, and the Sargent 130W is a mortise thumbturn with a round backplate in the 7800 Series. Both are turn pieces that operate a lock, not lock bodies. The Baldwin 6001 is the mortise lock body itself, with knob by knob operation, a 2-3/4 inch backset and a 1 inch throw deadbolt.

The Baldwin 6001 lock body is supplied right hand. Where handing is a risk on a mixed job, the BEST 45HCAC is a heavy duty public entrance mortise lock body with field reversible operation, and the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating. The Kaba Ilco 185 Series is supplied with no handing at all.

The 6001 uses knob by knob trim, which is not a push/pull or lever design. Where a facility requires otherwise, the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset in the 195 Series, ligature resistant, ADA compliant and satin stainless steel. The TownSteel MRX-L-01 is a Grade 1 heavy duty anti-ligature lever mortise lockset with passage function for 1-3/4 inch doors, and the MRX-A-01 is the arch trim version of the same passage lockset.

It is supplied in 031 non-lacquered brass. Non-lacquered means there is no clear coat, so the brass will patina and darken with handling over time rather than staying bright. If you are matching other Estate Series hardware in a living finish, that is the point of it; if you want it to stay bright, it is the wrong choice.
