No. The 6375 is built on a 2-1/2 inch backset, which is Baldwin's Estate Series dimension and not one of the two common American backsets (2-3/8 and 2-3/4 inches). The mortise pocket and the cross-bore centers have to match 2-1/2 inches or the knob spindle and cylinder will not line up with the holes in the door. If the door is prepped for a 2-3/4 inch backset mortise lock, something like the Hager 3800 Series or the Sargent 4874 deadbolt runs 2-3/4 inches instead.

Right hand reverse means the door is hinged on the right as you face it from the outside and it swings toward you (outswing). Stand outside the opening: hinges on your right, door pulls toward you, that is RHR. Hinges on the right and the door pushes away from you is plain right hand, and this lock body will not work on it. Mortise bodies of this type are handed at the factory, so the handing has to be right on the order.

Emergency egress means turning the inside knob retracts the deadbolt and the latch together, so a person inside gets out in one motion without having to throw the thumbturn first. It matters on any door someone could be behind when they need to leave in a hurry, and it is why this entrance function is specified on exterior residential doors that carry a 1 inch throw deadbolt.

The 6375 throws a 1 inch deadbolt and is set up for an ASA strike, which is the standard boxed mortise strike with the 1-1/4 by 4-7/8 inch face. A 1 inch throw needs a jamb pocket deep enough to take it, so a shallow residential strike box will bottom out the bolt. If the frame already has an ASA mortise strike prep, this drops in. If it is prepped for a cylindrical lock strike, the jamb has to be cut for the ASA strike.

The latch faceplate measures 1-1/4 x 8 inches, so the door edge has to be routed for a face that size with the mortise pocket behind it at a 2-1/2 inch backset. On a retrofit, measure the existing faceplate first: anything shorter than 8 inches means the edge mortise has to be extended, and that is visible work on a finished door.

This is the mortise lock body only, the case that goes inside the door edge. Knobs or levers, roses or escutcheons, the cylinder and the thumbturn are separate. Baldwin builds the 6375 to take knob by knob or lever by lever trim from the Estate Series, so pick the trim and the finish to match the rest of the openings before ordering.

Baldwin classifies the 6375 as residential hardware in the Estate Series, so it belongs on houses and high-end residential entries, not on commercial openings where a Grade 1 body and a code-compliant function are specified. For a commercial corridor or office door, a Grade 1 mortise lockset such as the Cal-Royal NM8050 entrance/office or the Corbin Russwin ML2003 classroom is the right family to look at instead.

The Baldwin 6375 is an entry mortise lock body with emergency egress, knob by knob, a 2-1/2 inch backset and a 1 inch throw deadbolt with saw-proof inserts. If the opening is a standard 1-3/4 inch commercial door instead, the Cal-Royal NM8440 is a Grade 1 mortise lockset with a deadbolt built into the case, rated for a 1-3/4 inch door, though its function is privacy/bed/bath rather than entrance. For a keyed entrance case on a 1-3/4 inch door, the Cal-Royal NM8050 is a Grade 1 entrance/office mortise lockset with an auxiliary deadlatch. The 6375 carries a 1-3/8 inch and over door thickness range, so it covers thinner doors than either Cal-Royal.

The Baldwin 6375 is an Estate Series residential entry mortise lock body. For a Grade 1 spec on a 1-3/4 inch door, the Cal-Royal NM8050 is a heavy duty Grade 1 entrance/office mortise lockset with an auxiliary deadlatch, and the Cal-Royal NM8080 is the Grade 1 storeroom version with an interchangeable core option. The Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever. Storeroom function keeps the outside trim always locked; entrance/office lets the outside be locked or unlocked, so match the function to how the door is used.

The Baldwin 6375 is a keyed entry mortise lock body with a working latch and a 1 inch throw deadbolt. The Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan are all mortise entrance locksets in dummy function - they carry no latch and no locking mechanism, so they mount on an inactive leaf for appearance only. The Schlage L0170 is a Grade 1 half dummy trim in dummy function as well. On the other end, the Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset and the Kaba Ilco 185 Series is deadbolt function - those give you the bolt with no latch, so a door that must latch closed still needs a lock case like the 6375.

Doors from 1-3/8 inches and up take this lock body, so a thinner interior-weight slab is fine as well as a standard 1-3/4 inch exterior door. Thickness drives the spindle and cylinder length you need, not the body itself.

A mortise body puts the latch and the 1 inch deadbolt in one case with a single 8 inch faceplate and one pocket in the door edge, and on this entry function the inside knob retracts both at once for egress. Two separate bores, a cylindrical knob plus a deadbolt above it, give you two independent locks and two motions to get out. The mortise route needs the door edge routed for the pocket, so it is the choice when the door is already prepped for one or when you want single-motion egress and heavier hardware on a thick entry door.

The deadbolt on the 6375 carries saw-proof inserts inside the 1 inch bolt, which are hardened pins that spin under a blade so the bolt cannot be cut through the gap between the door and the jamb. That is a meaningful difference from a plain brass or steel bolt on an outswing entry, where the bolt is more exposed.

The 6375 body is supplied right hand reverse. A door with the opposite swing or opposite hinge side takes a different handing of the same 6375 body, so determine the handing at each opening before ordering rather than assuming one body covers a matched pair of doors.

The 6375 is a purely mechanical, key-operated entry body. For keyless on a mortise prep, the Dormakaba E-Plex 2066 is a pushbutton keyless mortise lock, and the Alarm Lock DL2700CR Trilogy T2 is a Grade 1 electronic mortise lock with a weatherproof design for exterior openings. Those are commercial-grade bodies, so confirm the door prep and backset against the new lock rather than assuming the 2-1/2 inch Baldwin pocket carries over.

The Baldwin 6375 body is supplied right hand reverse, so the hand has to be identified before ordering. If you would rather carry one part that covers both swings, the BEST 45H Series heavy duty mortise lock body is field reversible in public entrance function, and the Falcon MA101 is a Grade 1 heavy-duty mortise lock with field reversible operation in passage function. The Kaba Ilco 185 Series is supplied with no handing. Note the function difference: passage does not lock, and the 6375 is an entry function case.

The Baldwin 6375 is a mechanical entry mortise lock body keyed at the cylinder. For coded or credential entry in a mortise pocket, the Dormakaba E-Plex E5086 is a Grade 1 entry/egress electronic pushbutton and card mortise lock in a back to back configuration, which keeps the egress behavior the 6375 offers. The Alarm Lock DL3500CR Trilogy is a Grade 1 electronic mortise lock with 300 user codes in classroom function for 1-5/8 to 1-7/8 inch doors, and the Accentra NTM623-NR nexTouch Generation 3 is a Grade 1 mortise lock with a capacitive touchscreen keypad and cylinder override, no deadbolt. Only the 6375 and the E5086 in that group are entry/egress cases.

No - those are trim, not lock cases. The Baldwin 6375 is a complete mortise lock body with a 1-1/4 inch by 8 inch latch faceplate and an ASA strike. The Sargent 130KB and the Sargent 130W are standard duty mortise thumbturns, the 130W with a round backplate, and they mount to a lock case that is already in the door. The Falcon MESC600DT is a dummy escutcheon lever trim for M9900 Series exit devices. Trim like that changes how a door is operated from one side; it does not provide the latch, bolt or keying.

The Baldwin 6375 provides emergency egress from an entry mortise case at a 2-1/2 inch backset. For an institutional corridor opening, the Sargent 7925 is a Grade 1 heavy duty mortise lock in dormitory exit function with rose trim and a single cylinder deadbolt, which gives the same free-egress behavior with an institutional trim package. The Corbin Russwin ML2003 is a Grade 1 classroom mortise lockset in the ML2000 Series for 1-3/4 inch doors if the room is keyed from the corridor side instead. The 6375 is an Estate Series residential case, so it is the wrong pick where the drawing calls a Grade 1 institutional lock.

The Baldwin 6375 takes a 2-1/2 inch backset in a door 1-3/8 inch and over, which suits a wood or thicker door. For a narrow ornamental iron door, the Marks USA 21AC is an entrance double cylinder Unilock ornamental iron mortise lock with a round knob for a 1 inch door, and the Marks USA 22AC is the 22 Series entrance double cylinder ornamental iron equivalent, also 1 inch. Both keep the knob operation and keyed entrance function of the 6375 in a case sized for a 1 inch thick door.

The Baldwin 6375 is a keyed entry case with a deadbolt. If the door only needs to close and 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 3800 Series Grade 1 passage mortise lock with rose and a 2-3/4 inch backset for 1-3/4 to 2-1/2 inch doors, with the 3810E the escutcheon version of the same. For a bathroom or bedroom, the Hager 3840S is a Grade 1 privacy mortise lock at a 2-3/4 inch backset. Note the backset change: those Hager bodies are 2-3/4 inch where the 6375 is 2-1/2 inch, so the mortise pocket and cross bore locations differ.

It is offered in 003 Polished Brass PVD. PVD is a plated coating rather than a lacquer, so it holds its color on an exterior door far better than plain polished brass. Trim ordered to match should be specified in the same 003 finish.

No. The Baldwin 6375 is a mortise lock body that seats in a pocket routed into the door edge and lands a 1-1/4 inch by 8 inch faceplate against an ASA strike. The Schlage PC10 is a Grade 1 passage cylindrical lock for 1-3/4 inch doors, which installs through a bored cross hole instead - a different door prep entirely. Every other mortise body, such as the Schlage PM010 Grade 1 passage latch mortise lock, uses the mortise prep. Confirm which prep the door already has before you order.
