The Baldwin 6001 is sold as the mortise lock body only. Levers, roses or escutcheons, and cylinders are separate items you specify to match the rest of the opening. If you are replacing a whole lockset rather than a failed case, budget for the trim as well.

It is built for doors 1-3/4 inches and thicker. That covers standard 1-3/4 inch doors as well as the heavier entry doors common on higher-end residential work. On a 1-3/8 inch interior door this is the wrong case.

The 6001 is cut for a 2-3/4 inch backset, which is the standard mortise backset on residential entry doors. If your current case measures 2-3/4 inches from the door edge to the spindle center, the pocket depth will match. Verify the face plate size and the deadbolt/latch spacing on the existing case before you commit, since a different maker's case can sit on the same backset with different cutouts.

Yes. The 6001 body is ordered handed, in left hand or right hand. Stand outside the door: if the hinges are on your left it is left hand, hinges on your right is right hand. Order the wrong one and the latch bevel faces the wrong way.

The Baldwin 6001 mortise lock body is an entrance/apartment function unit built for residential use with a 2-3/4 inch backset. For a heavier commercial opening, the Cal-Royal NM8050 is a Grade 1 entrance/office mortise lockset with an auxiliary deadlatch for 1-3/4 inch doors, and the Sargent 7925 is a Grade 1 corridor/dormitory function mortise lock with rose trim and a single cylinder deadbolt. Both are specified for commercial duty rather than residential trim, so the lever and rose styling will not match a Baldwin Estate Series opening.

The Baldwin 6001 is a keyed entry function with a 1 inch throw deadbolt, which is more lock than a bed or bath door needs. For privacy, the Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset for 1-3/4 to 2 inch doors, which matches the Baldwin's 2-3/4 inch backset, and the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors.

No. 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 surface applied with no latch or bolt operation, so none of them will secure the door. The Baldwin 6001 is an entry function mortise lock body with a 1 inch throw deadbolt with saw-proof inserts, and it requires a real mortise pocket.

Not on the same door. The Marks USA 21AC and 22AC are entrance double cylinder ornamental iron mortise locks with round knobs, both listed for 1 inch door thickness, which is narrow stile ornamental iron work. The Baldwin 6001 is built for doors 1-3/4 inch and over. Match the lock to the door thickness before comparing function.

It is the keyed entrance function used on apartment and house front doors: a latch operated by the lever from either side under normal use, plus a separate deadbolt for positive security. It is not a classroom or storeroom function, so the outside lever is not permanently locked.

The Baldwin 6001 is an entry/apartment function lock, which is not a classroom or storeroom function. For a classroom, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors, and the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with auxiliary deadlatch. For a storeroom, the Accentra 8805FL is a Grade 1 storeroom mortise lock with Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option.

The Baldwin 6001 is a mechanically keyed entrance/apartment mortise lock body. For electronic access on a mortise prep, the Schlage Electronics LEBMB-ADD is a Grade 2 mobile-enabled mortise lock with push button and LED offered in privacy, office, and apartment functions for 1-3/4 inch doors with a 3 hour fire rating, and the Dormakaba E-Plex E5086 is a Grade 1 entry/egress electronic pushbutton and card mortise lock. Both replace the mechanical cylinder-and-key operation of the 6001 with credential control.

The Baldwin 6001 is a keyed entrance/apartment mortise lock body. On a hall or closet door that only needs a latch, the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, and the Hager 3810S is a Grade 1 passage mortise lock with rose and a 2-3/4 inch backset, matching the Baldwin's 2-3/4 inch backset. Hager also offers the 3810E with escutcheon trim if you want a plate rather than a rose.

They are not equivalent. The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, so it shares the Baldwin 6001's 2-3/4 inch backset but provides bolt only with no latch and no lever operation. The Baldwin 6001 is a lever by lever entry/apartment lock body combining latch and a 1 inch throw deadbolt in one case. Use the 4874 only where a separate deadbolt above an existing latchset is intended.

The Baldwin 6001 lock body is ordered as left hand or right hand. If you would rather carry a single reversible part, the BEST 45H Series heavy duty mortise lock body is a public entrance function unit with field reversible operation, and the Falcon MA101 is a Grade 1 heavy-duty mortise passage lock with field reversible operation. The Kaba Ilco 185 Series mortise deadbolt is offered with no handing. Note the function differs from the Baldwin's entry/apartment in each case.

Ordered as the lever by lever entry/apartment configuration. The key features on the case also reference a knob by knob arrangement, so confirm the trim style you want when you select the levers or knobs, since the case itself takes either through the same spindle.
