Right hand reverse means the door is hinged on the right as you face it and it swings toward you (out). The Baldwin 6310 in the 190 Satin Black finish is built as a right hand reverse lock, so handing is determined at the time you order, not adjusted on site. Stand outside the opening: hinges on the right and the door pulling toward you is RHR. If the door pushes away from you with right hinges, that is standard right hand and you need the other hand.

The Baldwin 6310 is cut for a 2-1/2 inch backset, meaning the center of the knob or lever spindle sits 2-1/2 inches from the door edge. That is the standard residential mortise backset and it will not drop into a pocket cut for the 2-3/4 inch commercial backset without re-prepping the door and moving the trim holes. Measure from the door edge to the center of the existing spindle hole before ordering.

Probably not. The 6310 is a 2-1/2 inch backset residential mortise lock. Openings prepped at 2-3/4 inches are better matched by a commercial body like the Hager 3800 Series, which is built on a 2-3/4 inch backset and covers 1-3/4 to 2-1/2 inch doors, or the Corbin Russwin ML2003 for 1-3/4 inch doors. Use the Baldwin where you want the Estate Series look on a residential-prepped door.

The Baldwin 6310 is an Estate Series entrance/storeroom mortise lock built for residential use with a 2-1/2 inch backset. Where the opening calls for a certified commercial lockset, the Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset with an interchangeable core option for 1-3/4 inch doors, and the Accentra 8805FL is a Grade 1 storeroom mortise lock from the 8800 Series supplied with the Arcadia lever. Both are storeroom function rather than the Baldwin's entry function, so confirm whether you need the outside trim always locked or key-releasable.

The Baldwin 6310 in the 190 satin black finish is ordered right hand reverse, so the handing must be confirmed before purchase. Field reversible or non-handed alternatives include the BEST 45H Series heavy duty public entrance mortise lock body with field reversible operation, the Falcon MA101 Grade 1 heavy duty mortise passage lock with field reversible operation, and the Kaba Ilco 185 Series, which is supplied with no handing.

The Baldwin 6310 is a mechanical entry/storeroom mortise lock with no electrical provision. For electrified mortise openings, the Command Access ML190 Series is a heavy-duty motorized storeroom mortise lock with field selectable EL/EU operation at 24VDC, the BEST 45HW Series is a wired electromechanical mortise lock running 12V or 24V, and the Schlage L9092EU with 03A trim provides electric lock/unlock of the outside lever with request to exit at 12/24VDC on 1-3/4 inch doors.

The latch faceplate on the 6310 measures 1-1/4 by 8 inches, so the door edge needs a mortise pocket and faceplate mortise sized to that. If the existing lock body in the door has a faceplate of a different size, the edge prep has to be patched or enlarged to match.

It covers doors 1-3/8 inches and over, so both the 1-3/8 inch interior doors common in older homes and the 1-3/4 inch entry doors most exterior openings use are within range.

It is an entry function lock with a separate 1 inch throw deadbolt carrying saw-proof inserts. The key retracts the latch from outside and the deadbolt is thrown separately for real security, which is what you want on a front entry or a locked storage room where the door must stay secured but still be operable by key.

The Baldwin 6310 is a keyed entry/storeroom mortise lock with a 1 inch throw deadbolt and is not intended for privacy service. For bed and bath openings the Cal-Royal NM8440 is a heavy duty 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 doors 1-3/4 inch to 2 inch thick.

The Baldwin 6310 is entrance/storeroom function and does not provide classroom operation. For classroom openings, the Cal-Royal NM8070 is a heavy duty Grade 1 classroom mortise lockset with auxiliary deadlatch for 1-3/4 inch doors, and the Corbin Russwin ML2003 is a Grade 1 classroom mortise lockset from the ML2000 Series, also for 1-3/4 inch doors.

The Baldwin 6310 is a mechanical key-operated mortise lock. For credential entry on a mortise prep, the Alarm Lock DL2700CR Trilogy T2 is a Grade 1 electronic mortise lock with keypad and weatherproof design for doors 1-5/8 inch to 1-7/8 inch, the Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock for wide stile doors, and the Accentra NTM623-NR nexTouch Generation 3 uses a capacitive touchscreen keypad with cylinder override. These require a mortise pocket matched to their own backset and prep rather than the Baldwin 2-1/2 inch backset.

The Baldwin 6310 combines a latch with a 1 inch throw deadbolt in one mortise case. If the opening needs deadbolt only, the Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset from the 4870 Series, and the Kaba Ilco 185 Series is a no-handing deadbolt function mortise lock.

No. The Baldwin 6310 is a keyed entry function lock with a deadbolt. The Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock and the Schlage PC10 is a Grade 1 non-keyed passage cylindrical lock with rose, both for 1-3/4 inch doors. Passage hardware latches the door but does not lock, and the PC10 also requires a cylindrical bore rather than a mortise pocket.

The Baldwin 6310 is an Estate Series residential entry/storeroom mortise lock. For a corridor or dormitory opening in multi-family or institutional service, the Sargent 7925 is a Grade 1 heavy duty dormitory exit function mortise lock with rose trim and a single cylinder deadbolt, which gives the deadbolt behavior expected on that opening in a commercially graded body.

The Baldwin 6310 is a residential Estate Series lever-by-lever entry mortise lock and is not a ligature-resistant design. For those rooms, the TownSteel MRX-L-01 is a Grade 1 heavy duty stainless steel anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, the MRX-A-01 offers the same passage function with arch trim in satin stainless, and the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset that is ligature resistant and ADA compliant.

No. The Baldwin 6310 covers doors 1-3/8 inch and over, so a 1-3/4 inch door is within range, and its latch faceplate measures 1-1/4 by 8 inches against an ASA strike. Several peers are fixed to 1-3/4 inch only, including the Cal-Royal NM8080 and the Corbin Russwin ML2003, so if your stock includes thinner or thicker doors the Baldwin's wider thickness range is the one that spans them.

The Baldwin 6310 is a strictly mechanical keyed mortise lock. For code or credential entry on a mortise prep, the Dormakaba E-Plex 2066 pushbutton keyless mortise lock and the Alarm Lock DL2700CR Trilogy T2 electronic mortise lock are electronic alternatives; the DL2700CR fits doors 1-5/8 to 1-7/8 inches, so confirm your door falls in that band.

Finish 190, Satin Black. If you are matching other openings in the same building, 190 is the Baldwin code to specify so the hinges, trim and lock all read the same.
