The 8560 works with an ASA strike, which is the standard 1-1/4 by 4-7/8 inch mortise strike prep in a commercial-style jamb. The lock face itself is a 1 by 5-3/4 inch faceplate, so the door edge mortise has to accept that footprint. If your jamb already carries an ASA strike from another mortise lock, the frame side is done.

Body only. The 8560 is the mortise deadlock case itself, cylinder by turn, meaning it is keyed from the outside and operated by a thumbturn from the inside. It has no latch and no lever or knob, so it does not hold the door closed on its own. Plan on pairing it with a separate latch or handleset, and on supplying the cylinder, turn piece and escutcheon that match your Estate Series trim.

The Baldwin 8560 deadlock body is built to a 2-1/2 inch backset, so a pocket cut for 2-3/4 inch will leave the cylinder and turn off the centerline. For that prep the Sargent 4874 is a mortise deadbolt built to a 2-3/4 inch backset. The difference in trim is the operation: the 8560 is cylinder by turn, keyed outside with a thumbturn inside, while the 4874 is a double cylinder deadbolt, keyed on both sides. Confirm which side the building wants key-operated before ordering, since that changes egress behavior on the inside face.

The Baldwin 8560 is an Estate Series residential deadlock body with a heavy gauge steel case and solid forged brass working parts. Where a specification names ANSI Grade 1, the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset with an interchangeable core option, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset, and the Falcon MA101 is a Grade 1 heavy duty mortise passage lock that is fire rated and field reversible. Those three are all built for 1-3/4 inch doors, which is the common commercial leaf.

The 8560 is a deadlock body, meaning it throws a bolt and nothing else, so a separate latch or knob set has to carry the door closed. If a single mortise pocket should do both jobs, the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with a deadbolt for 1-3/4 inch doors, and the Sargent 7925 is a Grade 1 corridor and dormitory function mortise lock with rose trim and a single cylinder deadbolt. Both are heavier pockets than a deadlock body, so the door prep is not interchangeable with the 8560.

No. The Sargent 130KB and the 130W are mortise thumbturns - the turn trim that mounts on the inside face and drives a lock body that is already in the door. The Baldwin 8560 is the deadlock body itself, the steel case with the brass working parts and the 1 inch by 5-3/4 inch latch faceplate that sits in the door pocket, supplied cylinder by turn. A thumbturn will not throw a bolt on its own, so ordering one in place of the 8560 leaves the door with no lock in it.

No handing to specify. Both finishes of the 8560 deadlock body are reversible, so the same part goes into a left or right hand opening. That's one less thing to get wrong on a multi-door order, and it means a single spare covers every door in the house.

The 8560 is cylinder by turn, so the inside is always a thumbturn, no key. For a double cylinder mortise deadbolt, look at the Sargent 4874, which is a double cylinder mortise deadbolt on a 2-3/4 inch backset. Watch that backset difference: 2-3/4 will not drop into a door prepped for the Baldwin's 2-1/2 inch pocket.

That's a normal use for it. A deadlock body carries a deadbolt only, no latch, so it stacks above a latching handleset or knob set to add a keyed bolt. The door needs a second mortise pocket cut for the 1 by 5-3/4 inch faceplate at 2-1/2 inch backset, and the jamb needs an ASA strike at that height.

Not a like-for-like swap. The 8560 is a mechanical deadlock body on a 2-1/2 inch backset with no lever, keypad or credential reader. Electronic mortise locks like the Alarm Lock DL4500 electronic mortise deadbolt run 1-5/8 to 1-7/8 inch door thickness and the Schlage CO-100 standalone keypad mortise lock is prepped for 1-3/4 inch doors, both with different door cutouts. If you want to keep keyless access, stay with an electronic unit rather than reprepping the door for the Baldwin.

The 8560 is operated by cylinder outside and turn piece inside. For code entry on a mortise deadbolt, the Alarm Lock DL4500 series is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad, fitted to doors 1-5/8 to 1-7/8 inch thick. If the opening also needs a latch, the Alarm Lock DL3500CR is a Grade 1 electronic mortise lock with 300 user codes and classroom function in the same door thickness range. Both need a wider door thickness check than the 8560, which takes doors 1-3/8 inch and over.

The 8560 deadlock body is set up for doors 1-3/8 inch and over with an ASA strike, which assumes a conventional stile. For thin ornamental iron doors, the Marks USA 21AC and 22AC are entrance double cylinder mortise locks built for a 1 inch door thickness. For a glass door with a bottom rail, the Kaba Ilco BR series is a bottom rail lock made for that condition. Those are different door preps entirely, so measure the stile before choosing.

The Baldwin 8560 is supplied reversible, so one body covers either hand of door. The Kaba Ilco 185 series is also a deadbolt function mortise lock supplied with no handing. Among latching mortise locks, the BEST 45H series public entrance lock body is field reversible and the Falcon MA101 Grade 1 passage lock is field reversible as well, which means the hand is set during installation rather than at the time of order.

The Baldwin 8560 comes in 003 polished brass PVD and 190 satin black and is a working deadlock body. Where the opening needs a decorative mortise entrance set that does not operate - an inactive leaf or a pull side - the Emtek 3019 Brisbane, 3102 Memphis, 3104 Hamilton and 3106 Manhattan are dummy function mortise entrance locksets. Those are trim only, so on an active door they are used alongside a working bolt such as the 8560 rather than in place of it.

They do opposite jobs. The Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors - it holds the door closed and never locks. The Baldwin 8560 is a keyed deadlock body with a turn piece inside and no latch at all. On a door that must both stay shut and lock, the two are installed together in separate preps, or a single lockset with both functions is used instead, such as the Cal-Royal NM8050 Grade 1 entrance and office mortise lockset with auxiliary deadlatch.

Two: 003 Polished Brass PVD and 190 Satin Black. PVD polished brass is the plated finish that resists tarnish, so it's the one to pick if the entry sees weather and you don't want to be polishing brass. Both come reversible.

Heavy gauge steel case with solid forged brass working parts, brass and steel throughout. Forged brass internals are what you want on an entry that gets cycled daily, and the steel case gives the mortise pocket a rigid shell so the bolt stays aligned in a heavy solid-core or wood entry door.
