Yes. The Baldwin 6020 entrance mortise lock body is built for doors 1-3/4 inches and over, which covers the standard exterior door thickness on most homes as well as heavier custom entry doors. If your door is thinner than 1-3/4 inches, this is the wrong body for it.

Handing matters. The 6020 lock body is ordered as either left hand or right hand, not field reversible on the order form. Stand outside the door on the key side: if the hinges are on your left, it's a left hand door; hinges on the right, right hand. Get this wrong and the latch bevel faces the wrong way.

The deadbolt is built into the 6020 body. It throws 1 inch and carries saw-proof inserts in the bolt. No separate deadbolt case is needed above the handleset, and no second mortise pocket.

No. The 6020 is a residential entrance body, handleset by knob, and it isn't the right choice for a commercial opening or a rated corridor door. For a commercial mortise entrance, look at the Cal-Royal NM8050 Grade 1 office/entrance mortise lockset for 1-3/4 inch doors, or the Hager 3850E 3800 Series Grade 1 office mortise lock with a 2-3/4 inch backset. Both are heavy duty commercial bodies rather than residential.

It's the mortise lock body only, the case that goes into the door edge pocket. The exterior handleset, interior knob, and cylinder are separate items. Order it to match the handing and finish of the trim you're pairing it with.

The Baldwin 6020 is a residential entrance mortise lock body with a 2-3/4 inch backset, and among other brands the Hager 3800 Series carries the same 2-3/4 inch backset in a mortise body: the Hager 3810S is a Grade 1 passage mortise lock with rose and 2-3/4 inch backset, and the Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon, non-keyed, at the same 2-3/4 inch backset. The difference to weigh is function: the Baldwin 6020 is an entrance function with a 1 inch throw deadbolt with saw-proof inserts that deadlocks the latch bolt when extended, while the Hager 3810S is passage and the 3850E is office and non-keyed. Match the backset first, then confirm the function is the one the opening needs.

The Baldwin 6020 is a residential entrance mortise lock, so on an opening written for a commercial Grade 1 entrance the Cal-Royal NM8050 is the closer fit: it is a heavy duty Grade 1 office/entrance mortise lockset with auxiliary deadlatch for 1-3/4 inch doors. The BEST 45HCAC is another route, a heavy duty mortise lock body in public entrance function with field reversible operation. Both are entrance-family mortise bodies specified at commercial duty, where the Baldwin 6020 is built for residential entrance service on doors 1-3/4 inch and over.

No, those are not substitutes for the working lock. The Emtek 3102 Memphis and Emtek 3104 Hamilton are mortise entrance locksets in dummy function, as are the Emtek 3106 Manhattan and the Emtek 3019 Brisbane. Dummy trim does not latch or lock and carries no bolt. The Baldwin 6020 is an entrance function mortise lock body with a 1 inch throw deadbolt with saw-proof inserts. Use an Emtek dummy only on the inactive leaf of a pair or a fixed panel, and keep an operating entrance body on the active door.

The Baldwin 6020 is built for doors 1-3/4 inch and over, so on a thinner door it is the wrong body. The Marks USA 21AC entrance double cylinder Unilock ornamental iron mortise lock with round knob and the Marks USA 22AC entrance double cylinder ornamental iron mortise lock are both listed for 1 inch door thickness, which is the range for narrow ornamental iron doors. Both are entrance double cylinder locks, so both sides are keyed, where the Baldwin 6020 is a residential entrance body from the Estate Series.

The Baldwin 6020 is entrance function, so a classroom or storeroom opening needs a different body. For classroom, 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 mortise classroom lockset in the ML2000 Series, also 1-3/4 inch. For storeroom, 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. Confirm the function on the door schedule before ordering, because the function is what changes here, not the mortise pocket.

Throwing the deadbolt deadlocks the latch bolt as well, so the knob will not retract the latch while the bolt is out. That's the security behavior you want on a front entry: one turn locks both the bolt and the latch together.

The 6020 is a mechanical key-operated body with no electronic option. If you want keyless on a mortise prep, the Dormakaba E-Plex 2066 electronic pushbutton keyless mortise lock or the Alarm Lock DL2700CR Trilogy T2 (1-5/8 to 1-7/8 inch doors, weatherproof) are the keypad routes. Note the DL2700CR's thinner door range, which won't cover the heavy 1-3/4 inch and over doors the Baldwin body is meant for.

The Baldwin 6020 is an entrance mortise lock body that combines a latch bolt with a 1 inch throw deadbolt with saw-proof inserts, where the extended deadbolt deadlocks the latch. If the opening needs deadbolt only, the Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset, matching the Baldwin 6020 backset without the latch. The Kaba Ilco 185 Series mortise lock is also a deadbolt function and is supplied with no handing, which removes the left hand and right hand decision the Baldwin 6020 requires.

The Baldwin 6020 is a keyed residential entrance mortise body. For keyless entry in a mortise prep, the Dormakaba E-Plex E5086 is a Grade 1 entry/egress electronic pushbutton and card mortise lock in a back to back configuration, and the Dormakaba E-Plex 2066 is an electronic pushbutton keyless mortise lock. The Accentra NTM623-NR nexTouch Generation 3 mortise lock uses a capacitive touchscreen keypad and has no deadbolt but does provide cylinder override. Note that difference against the Baldwin 6020, which carries a 1 inch throw deadbolt that deadlocks the latch bolt when extended.

No. The Sargent 130KB is a standard mortise thumbturn and the Sargent 130W is a mortise thumbturn with a round backplate. Those are turn pieces that operate a bolt from the inside, not lock bodies, and they do not contain a latch or a deadbolt. The Baldwin 6020 is the entrance mortise lock body itself, with a 2-3/4 inch backset and a 1 inch throw deadbolt with saw-proof inserts. If the existing body is sound and only the interior turn is damaged, a thumbturn is the part to order; if the bolt work is failing, the body is.

The Baldwin 6020 is ordered as left hand or right hand, in Venetian Bronze 112 or Satin Black 190. If handing is a risk on a retrofit where the swing is not confirmed, the BEST 45HCAC heavy duty mortise lock body in public entrance function is field reversible, and the Falcon MA101 Grade 1 heavy duty mortise passage lock is also field reversible. The Kaba Ilco 185 Series mortise lock is supplied with no handing. Those differ in function from the Baldwin 6020 entrance body, so reversibility is only useful if one of those functions suits the door.

Neither will secure the door. The Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, and the Schlage PC10 is a Grade 1 passage cylindrical lock, non-keyed with rose, both for 1-3/4 inch doors. Passage means latching only with no locking, and the PC10 is cylindrical rather than mortise, so it will not fill a mortise pocket at all. The Baldwin 6020 is a keyed entrance mortise body with a 1 inch throw deadbolt. Passage hardware belongs on a hall or closet door, not on an entry.

The Hager 3840S is a Grade 1 privacy mortise lock with a 2-3/4 inch backset for doors 1-3/4 inch to 2 inch, which is the right function for a bed or bath door that needs to be locked from inside without a key. The Baldwin 6020 is a keyed entrance body for doors 1-3/4 inch and over. The Cal-Royal NM8440 is another privacy route, a heavy duty Grade 1 privacy mortise lockset with deadbolt for 1-3/4 inch doors. The backset matches on the 3840S, so the change is function, not prep.

Several electronic mortise locks drop into a mortise prep. The Schlage Electronics LEBMB-ADD is a mobile-enabled Grade 2 mortise lock with push button and LED covering privacy, office and apartment functions, rated 3 hours fire and listed for 1-3/4 inch doors. The Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and a mobile enabled deadbolt with LED on Greenwich trim, right hand, also 3 hour fire rated. The Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes in classroom function for 1-5/8 inch to 1-7/8 inch doors. The Baldwin 6020 remains the mechanical residential entrance body for doors 1-3/4 inch and over, so units staying on keys can keep it while selected doors move to credentials.
