No. The Baldwin 6375 lock body is a 2-1/2 inch backset, which is the Estate Series residential backset, not the 2-3/4 inch commercial standard. If your pocket and cross-bores are laid out for 2-3/4 inches, the spindle and cylinder holes will not line up and you would need to re-prep the door. Measure from the door edge to the center of the knob or lever hole before ordering.

It is an entrance function with emergency egress, which means a single motion on the inside lever retracts both the latch and the 1 inch deadbolt at once. Someone inside never has to turn a thumbturn first to get out, even with the deadbolt thrown. That is why it gets specified on apartment and residential front doors where free egress matters.

It takes an ASA strike, the standard curved-lip mortise strike. With a 1 inch deadbolt throw, the frame also needs a deadbolt pocket deep enough to take the full inch behind the strike plate. If you are replacing an older mortise lock that used a smaller T-strike, plan on cutting the jamb for the ASA prep.

No. The 6375 is a residential Estate Series lock body, so it is not the part for a commercial opening that needs a Grade 1 lock. For that, look at a Grade 1 mortise such as the Corbin Russwin ML2003 classroom lockset, the Cal-Royal NM8050 office/entrance mortise lockset, or the BEST 45H public entrance lock body.

This is the 6375 mortise lock body only. It is configured for lever by lever (the same body also serves knob by knob applications), but the levers, rosettes or escutcheons, and the cylinder are ordered separately in the finish you want. Budget for that trim when you price the opening.

The Baldwin 6375 is an entry-function residential mortise lock body with a 2-1/2 inch backset, so both levers are always operable from inside and it does not offer classroom lockdown. For a classroom opening, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors, the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with auxiliary deadlatch, and the Marks USA LA318GJ adds a classroom security indicator with an ANSI strike. For an office function specifically, the Hager 3850E is an office mortise lock with lever and escutcheon on a 2-3/4 inch backset.

The Baldwin 6375 is an entry-function mortise lock body with a 2-1/2 inch backset and a 1 inch throw deadbolt, catalogued for residential use in the Estate Series. 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 heavy duty dormitory exit function mortise lock with rose trim and a single cylinder deadbolt. Note the backset difference: the Baldwin is 2-1/2 inch, while the Hager 3800 Series mortise locks use a 2-3/4 inch backset, so the pocket prep is not the same.

The Baldwin 6375 is an entry-function lock body with a 1 inch throw deadbolt and emergency egress, so turning the inside lever retracts both latch and bolt. If you want both sides keyed instead, the Marks USA 21AC and 22AC are entrance double cylinder mortise locks with round knobs for 1 inch doors, and the Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset with no latch at all.

No. The Baldwin 6375 is a working entry mortise lock body with a 1 inch throw deadbolt and an ASA strike. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan mortise entrance locksets are dummy function, meaning they are non-operating trim for an inactive leaf. The Schlage L0170 is likewise a Grade 1 mortise half dummy trim. None of those latch or lock, so they are not an alternative for an active entry door.

The Baldwin 6375 covers doors 1-3/8 inch and over, uses a 2-1/2 inch backset, and has a 1-1/4 inch by 8 inch latch faceplate with an ASA strike, so a 1-3/4 inch door is within range as long as the pocket is cut for a 2-1/2 inch backset. If the existing pocket is a 2-3/4 inch backset, the Hager 3810S passage and 3850E office mortise locks are built on that backset, and the Cal-Royal NM8050 Grade 1 entrance/office is specified for 1-3/4 inch doors.

The latch faceplate measures 1-1/4 x 8 inches, so the door edge has to be mortised for that footprint with the pocket behind it. If the door you are retrofitting has a shorter or narrower faceplate cutout, the edge will need to be enlarged and patched.

It suits residential unit entries where you want a keyed entrance function with single-motion egress from inside, and the 1-3/8 inch and over thickness range covers most unit doors. The catch is handing: this is a left hand body, so you will need the matching right hand body for the openings that swing the other way. Walk the doors and count hands before you order the fleet.

The 6375 is a mechanical keyed entrance body with no electronic option. For keypad or credential access in a mortise pocket, the Alarm Lock DL3500CR Trilogy is a Grade 1 electronic mortise with 300 user codes, the Dormakaba E-Plex 2066 is a pushbutton keyless mortise lock, and the Schlage CO-100 is a standalone electronic mortise with a keypad reader. Note those are commercial-duty bodies with different backset and prep requirements than the Baldwin.

The Baldwin 6375 is an entry function: the interior lever always retracts the latch and the 1 inch deadbolt for emergency egress. A storeroom lock keeps the outside lever locked at all times and is key-only from the corridor side. The Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option.

The Baldwin 6375 is a mechanical entry mortise lock body operated by key and lever. If you want to drop keys, the Dormakaba E-Plex E5086 is a Grade 1 entry/egress electronic pushbutton and card mortise lock in a back-to-back configuration, the Alarm Lock DL2700CR Trilogy T2 is a Grade 1 classroom-function electronic mortise lock with a weatherproof design for 1-5/8 to 1-7/8 inch doors, and the Accentra NTM623-NR nexTouch Generation 3 uses a capacitive touchscreen keypad with cylinder override and no deadbolt. Keep in mind the E5086 and the Baldwin serve the same egress intent, while the NTM623-NR has no deadbolt.

The Baldwin 6375 is a keyed entry function, which is more than a bedroom or bathroom needs. For privacy, the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors, and the Hager 3840S is a Grade 1 privacy mortise lock on a 2-3/4 inch backset for 1-3/4 to 2 inch doors. For a non-locking hall or closet door, the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock and the Falcon MA101 is a Grade 1 heavy duty field reversible mortise passage lock.

The Baldwin 6375 is a mechanical entry lock body with no electrical provision. For an access control tie-in, the Schlage L9092EU with 03A lever is an electric lock/unlock outside lever mortise lock, keyed outside, with request to exit and 12/24VDC operation for 1-3/4 inch doors; the BEST 45HW is a wired electromechanical mortise lock with 12V/24V operation; and the Command Access ML190 is a heavy-duty storeroom mortise lock with field selectable EL/EU operation on 24VDC.

The Baldwin 6375 lock body is specified left hand. If handing is unknown or you want one part number to cover both, the BEST 45HCAC public entrance mortise lock body and the Falcon MA101 passage mortise lock are both field reversible, and the Kaba Ilco 185 Series mortise deadbolt lock requires no handing at all.

Two: 102 Oil Rubbed Bronze and 260 Polished Chrome. Match the body finish to the trim and cylinder you order so the exposed faceplate on the door edge does not clash with the rest of the opening.
