The 6320 lock body covers doors 1-3/8 inches and over, so it handles both the older 1-3/8 inch interior door and the 1-3/4 inch standard exterior door most entry openings use. Thicker custom entry doors are also within range.

Handing matters. The 6320 is built left hand or right hand, not field reversible on the order form, so the hand has to be picked when you buy. Stand outside the door (the keyed side): if the hinges are on your left, it's a left hand door. Get it wrong and the latch bevel faces the wrong way.

The 6320 uses an ASA strike, the standard mortise lock strike shape, so if the jamb already carries an ASA prep from another mortise lock the strike location generally carries over. The deadbolt throws 1 inch, so the strike box behind it needs a full inch of clear depth. The latch faceplate measures 1-1/4 x 8 inches, which is the cutout the door edge has to match.

This is the mortise lock body only, the mechanism that goes inside the door pocket for a handleset-by-knob trim arrangement. The exterior handleset and interior knob trim are ordered separately in the matching Estate Series design and finish. If you're replacing a worn-out mechanism behind trim you're keeping, the body alone is what you want.

The 6320 is a residential mortise lock, built for single-family and residential entry doors, not for the cycle counts or code requirements of a commercial opening. For a commercial entrance door, a Grade 1 mortise lockset is the right class of product: the Cal-Royal NM8050 is an office/entrance function Grade 1 mortise lockset for 1-3/4 inch doors, and the Corbin Russwin ML2003 covers the same door thickness in the ML2000 Series. Both are lever products on a 1-3/4 inch door rather than a residential handleset.

The Baldwin 6320 mortise lock body is built to a 2-1/2 inch backset, which is the residential handleset dimension. If the door is prepped for a 2-3/4 inch backset, the Hager 3800 Series is the match: the 3810S is a Grade 1 passage mortise lock with rose and a 2-3/4 inch backset, the 3810E is the same passage lock with an escutcheon, and the 3850E is a Grade 1 office mortise lock with lever and escutcheon, non-keyed, at 2-3/4 inch backset. The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset if the opening needs deadbolt only.

No. The Emtek 3102 Memphis mortise entrance lockset is a dummy function, as are the Emtek 3104 Hamilton, 3106 Manhattan, and 3019 Brisbane brass mortise entrance locksets. Dummy trim has no working latch or bolt and mounts to an inactive leaf. The Baldwin 6320 is an entry function mortise lock body with a 1 inch throw deadbolt with saw-proof inserts. Use the Emtek dummy locksets only on the fixed leaf of a pair where the 6320 handles the active door.

The Baldwin 6320 is a residential entry mortise lock body with a 2-1/2 inch backset and an ASA strike. For a commercial opening on a 1-3/4 inch door, the Cal-Royal NM8050 is a heavy duty Grade 1 office/entrance mortise lockset with an auxiliary deadlatch, listed for a 1-3/4 inch door thickness. The NM8050 keeps the entrance/office function while moving to a Grade 1 commercial lockset rather than a residential body.

Entry function on the 6320 means the exterior handleset is keyed and the interior knob retracts the latch, with a separate 1 inch throw deadbolt operated by the key outside and a turn inside. The deadbolt carries saw-proof inserts, hardened pins that stop a blade from cutting through the bolt. It's the standard front-door setup: latch for everyday use, deadbolt for when you want it locked.

If the door already has a working latch and you only want the bolt, a dedicated mortise deadbolt is the simpler buy. The Sargent 4874 is a double cylinder mortise deadbolt on a 2-3/4 inch backset, and the Kaba Ilco 185 Series is a no-handing mortise deadbolt. The Baldwin 6320 is worth the extra only when you want the latch and the 1 inch deadbolt in one body behind a handleset.

The 6320 is the Estate Series entry mortise body for a handleset-by-knob opening, so it stays within the same collection as the Estate trim already hanging on those doors. Two things decide whether it actually drops in: the existing pocket has to be a 2-1/2 inch backset mortise prep with a 1-1/4 x 8 inch faceplate cutout, and the hand of each door has to be ordered individually. Finish continuity across a fleet is straightforward since all four finishes come in both hands.

The Baldwin 6320 is a keyed entry mortise lock operated by handleset outside and knob inside. For credential entry on a unit door, the Schlage Electronics LEBMB-ADD is a mobile-enabled mortise lock with push button and LED covering privacy, office, and apartment functions, Grade 2, with a 3 hour fire rating, for a 1-3/4 inch door. The Dormakaba E-Plex 2066 Series is an electronic pushbutton keyless mortise lock, and the Dormakaba PowerPlex P2066 Series is a mortise lock in the same pushbutton family. The Accentra NTM623-NR nexTouch Generation 3 mortise lock uses a capacitive touchscreen keypad with cylinder override and no deadbolt, so it does not carry the deadbolt the 6320 provides.

The Baldwin 6320 is an entry function mortise lock, keyed from the outside. A bath or bedroom door takes a privacy function instead. 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, and the Cal-Royal NM8440 is a heavy duty Grade 1 privacy mortise lockset with deadbolt for a 1-3/4 inch door. Both replace the keyed cylinder with inside thumbturn privacy operation.

They are different pieces of the opening. The Baldwin 6320 is a complete entry mortise lock body with a 2-1/2 inch backset, an ASA strike, and a 1-1/4 by 8 inch latch faceplate. 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. Those are inside turn pieces that fit an existing mortise case; they do not contain a latch or bolt.

Not as a like-for-like. The Kaba Ilco 185 Series mortise lock is a deadbolt function with no handing, sold in a single pack. The Baldwin 6320 is an entry mortise lock body with both a latch operated by the handleset and knob and a 1 inch throw deadbolt, and it is ordered left hand or right hand. Swapping to the 185 Series gives bolt-only security and leaves the door without a latching handle set.

The Baldwin 6320 mortise lock body is ordered as left hand or right hand, so the handing has to be determined before the order goes in. If the job needs one part number that covers either hand, the BEST 45H Series heavy duty mortise lock body in public entrance function is field reversible, and the Falcon MA101 is a Grade 1 heavy duty mortise passage lock with field reversible operation and a fire rating. Both are commercial function locks rather than residential entry.

The Schlage PC10 is a Grade 1 passage cylindrical lock, non-keyed, with rose, for a 1-3/4 inch door. It is a bored cylindrical lock, so it needs a round cross-bore rather than the mortise pocket the Baldwin 6320 requires, and it is non-keyed passage rather than entry. If the door already has a mortise pocket and only needs passage, the Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, which drops into the mortise prep.

The Baldwin 6320 is a mortise lock body with a 2-1/2 inch backset and a 1-1/4 by 8 inch faceplate for a wood or similar door 1-3/8 inch and over. Glass and narrow aluminum openings take different hardware: the Kaba Ilco BR Series is a glass door bottom rail lock, and the Alarm Lock DL1300NW Trilogy Networx wireless electronic mortise lock with keypad is built for Adams Rite deadlatches. The Dormakaba E-Plex 2066 Series is listed for wide stile doors.

Four: 003 Polished Brass PVD, 044 Satin Brass PVD, 056 Lifetime PVD Satin Nickel, and 102 Oil Rubbed Bronze. Each is available in both left and right hand. The PVD finishes are the ones to match if the rest of the openings in the house are already Baldwin PVD brass or nickel; 102 Oil Rubbed Bronze is a living finish that changes with wear.

The Baldwin 6320 is a mechanical entry mortise lock body operated by handleset and knob. For a panel-controlled opening, the Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock, keyed outside, with request to exit, 12/24VDC, for a 1-3/4 inch door in corridor function. The BEST 45HW Series is a heavy duty wired electromechanical mortise lock with 12V/24V operation, and the Command Access ML190 Series is a heavy-duty motorized mortise lock with field selectable EL/EU operation on 24VDC in storeroom function.

The Baldwin 6320 is entry function: the outside handleset can be left unlocked or locked. A service door usually wants storeroom function, where the outside stays locked at all times and a key retracts the latch. The Accentra 8805FL is a Grade 1 storeroom mortise lock with Arcadia lever in the 8800 Series, and the Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset with an interchangeable core option for a 1-3/4 inch door.

The Baldwin 6320 is a residential entry mortise lock with a handleset and knob. Behavioral health and similar openings call for ligature resistant trim instead. The TownSteel MRX-L-01 is a stainless steel Grade 1 heavy duty anti-ligature lever mortise lockset in passage function for a 1-3/4 inch door, and the MRX-A-01 is the same passage function with satin stainless steel ligature resistant arch trim. The Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset, ligature resistant and ADA compliant, in satin stainless steel.

The Baldwin 6320 carries a 1 inch throw deadbolt with saw-proof inserts, thrown by the key or inside turn. For keypad control of the bolt, the Alarm Lock DL4500 Series is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad, for doors 1-5/8 to 1-7/8 inches. The Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and mobile enabled deadbolt with LED, Greenwich trim, right hand, with a 3 hour fire rating.
