Omnia 12043/A32D – Frequently Asked Questions

1) Do I have to specify handing when ordering the Omnia 12043 mortise lockset?
Handing is required on the Omnia 12043, left hand or right hand. Stand outside the door (the side you key or push in from), and if the hinges are on your left it is a left hand door, hinges on your right is right hand. The lever and latch are set up for that hand, so this is not something you correct on site.
2) Is the Omnia 12043 mortise lockset heavy enough for a commercial building, or should I be buying Grade 1?
The Omnia 12043 is built for residential use, so it suits single-family entries, condo and apartment unit doors and interior swings. For a school, hospital, or high-traffic institutional opening where the spec calls out a grade, go to a Grade 1 mortise instead: the Cal-Royal NM8070 classroom or NM8440 privacy, both Grade 1 for 1-3/4 inch doors, or the Falcon MA101 Grade 1 heavy duty passage mortise, which is fire rated.
3) Why choose a mortise lockset like the Omnia 12043 instead of a bored cylindrical lock?
A mortise lock like the Omnia 12043 drops into a rectangular pocket routed into the door edge rather than a round cross-bore, which is why it carries a bigger case and, in functions like panic-proof and double cylinder, a deadbolt in the same body. The trade is prep: cutting a mortise pocket in an existing door is real work, and if your door already has a 2-1/8 inch cross-bore you are better off with a cylindrical lock such as the Schlage PC10 Grade 1 passage. Choose mortise when the door is already prepped for one, or when you want latch and deadbolt in a single case.
4) What is the closest Grade 1 equivalent to the Omnia 12043 mortise lever lockset in storeroom function?
The Omnia 12043 is a residential mortise lever lockset offered in a storeroom function among its options. For a Grade 1 storeroom mortise lock, the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series with an Arcadia lever, and the Cal-Royal NM8080 is a Grade 1 storeroom mortise lockset for 1-3/4 inch doors with an interchangeable core option. The Omnia is built for residential use, while both of those are specified at Grade 1.
5) I need a mortise classroom lock for a school corridor instead of a residential one - what should I use?
The Omnia 12043 offers a classroom function but is a residential lockset. For an institutional classroom opening, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset in the ML2000 Series for 1-3/4 inch doors, and the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with an auxiliary deadlatch, also for 1-3/4 inch doors. The TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset for 1-3/4 inch doors with RFID credential reading if the facility is moving to cards.
6) What looks like a substitute for the Omnia 12043 but is only a lock body without trim?
The Omnia 12043 is a complete mortise lever lockset supplied with plates. Several mortise parts that come up in the same search are bodies or trim only: the BEST 45HCAC is a heavy duty mortise lock body in public entrance function with field reversible operation, the Baldwin 6301LS is a lever by lever entry/apartment mortise lock body with a 2-1/2 inch backset for doors 1-3/4 inch and over, and the Schlage L0170 is Grade 1 heavy duty half dummy trim in the L Series for 1-3/4 inch doors. Those require the matching complement to make a working opening.
7) The Omnia 12043 takes a 2-1/2 or 2-3/4 inch backset - what mortise locks match those backsets?
The Omnia 12043 is ordered with either a 2-1/2 inch or 2-3/4 inch backset. On the 2-1/2 inch side, the Baldwin 6301 entry/apartment and Baldwin 6310 entry/storeroom mortise lock bodies are both 2-1/2 inch backset, the 6310 covering doors 1-3/8 inch and over. On the 2-3/4 inch side, the Hager 3850E is a Grade 1 office mortise lock with lever and escutcheon, non-keyed, at 2-3/4 inch backset for doors 1-3/4 inch to 2-1/2 inch, and the Sargent 4874 mortise deadbolt is also 2-3/4 inch backset.
8) Do I need to specify handing on a mortise lever lockset, or are there reversible alternatives?
The Omnia 12043 requires a left handed or right handed selection at order time. Where handing is not known until the door is in front of the installer, the BEST 45HCAC heavy duty mortise lock body and the Falcon MA101 Grade 1 heavy-duty mortise passage lock are both field reversible, and the Kaba Ilco 185 Series mortise deadbolt is a no-handing part.
9) What satin stainless steel mortise lockset works for a behavioral health or ligature resistant opening?
The Omnia 12043 is a satin stainless steel US32D mortise lever lockset built for residential use. For a ligature resistant opening in the same finish family, the TownSteel MRX-L-01 is a stainless steel Grade 1 heavy duty anti-ligature lever mortise lockset in passage function for 1-3/4 inch doors, the MRX-A-01 is the same passage function with satin stainless steel arch trim, and the Marks USA 5PDN is a Grade 1 hospital passage mortise push/pull paddleset in satin stainless steel that is ligature resistant and ADA compliant.
10) Is a cylindrical passage lock an acceptable swap for a mortise lever lockset?
No. The Omnia 12043 is a mortise lock, which sits in a pocket cut into the door edge. The Schlage PC10 is a Grade 1 non-keyed passage cylindrical lock with a rose for 1-3/4 inch doors - a cylindrical prep with bored holes, not a mortise pocket. If the door is already mortised, the Schlage PM010 Grade 1 passage latch mortise lock for 1-3/4 inch doors is the mortise counterpart of that same passage function.
11) What is the difference between the storeroom and classroom versions of the Omnia 12043 mortise lockset?
Both are keyed outside on the Omnia 12043, and the difference is what the key does. Storeroom keeps the outside lever locked at all times and the key retracts the latch for entry; nobody can leave it unlocked by accident, which is what you want on a mechanical room or a store. Classroom lets the key unlock and relock the outside lever so it can be left free during the day and locked when needed. Inside lever is always free on both, so egress is never blocked.
12) What is the panic-proof function on the Omnia 12043 and when would I use it?
Panic-proof on the Omnia 12043 means turning the inside lever retracts the latch and the deadbolt together in one motion, so someone can get out in a hurry without hunting for a thumbturn. It is the function to specify on an apartment or unit entry door where a deadbolt is thrown from inside and you still need single-motion egress. A plain double cylinder version, also offered, is the opposite trade: it is keyed both sides, so no one gets out without a key.
13) Will the Omnia 12043 lever work for ADA accessibility on a residential entry?
The Omnia 12043 uses a lever handle rather than a knob, which is the operable-without-grasping form ADA calls for and the reason lever hardware gets specified on unit entries and common-area doors. It is a residential-duty lockset, so for a facility door carrying a Grade 1 commercial spec, look at something like the Cal-Royal NM8080 storeroom mortise lockset or the Corbin Russwin ML2003 instead.
14) How much clearance do I need on the door face and edge for the Omnia 12043 lockset plate?
The Omnia 12043 measures 10-9/16 x 2-3/8 x 2-5/8 inches, the last of those being the projection off the door face. The 10-9/16 and 2-3/8 figures cover the plate footprint, so you need a flat, unobstructed area of that size on the stile clear of any glass bead, panel moulding or astragal. On a narrow or heavily moulded stile that plate is what runs you out of room, not the lock case.
15) I need a 2-1/2 inch backset mortise lock body for a residential entry, what are my options besides the Omnia 12043?
The Omnia 12043 takes a 2-1/2 inch backset as one of its two choices. If you want the lock body alone rather than a full trimmed lever set, Baldwin's 6301LS is an entry/apartment lever-by-lever mortise body at 2-1/2 inch backset for doors 1-3/4 inch and over, and the Baldwin 6310 entry/storeroom is the same backset for doors 1-3/8 inch and over. The Baldwin bodies are the pick when you are reusing existing trim; the Omnia comes as a set with its plates.
16) Can I use the Omnia 12043 on a pair of doors where one leaf does not open?
Yes, and the pair dummy and single dummy functions on the Omnia 12043 exist for exactly that. Put the active function (keyed, privacy or passage) on the operating leaf and a dummy on the fixed leaf so both sides look identical. Pair dummy gives you levers on both faces of the inactive leaf; single dummy is one face only, for a leaf that is never touched from the far side.
17) Does the Omnia 12043 come with the plates, or do I order trim separately?
Plates are included with the Omnia 12043; it ships as a lever set with its mounting plates rather than a bare lock body. What you still specify at order is function, handing and backset. If you only need the case because you are keeping existing trim, a lock body such as the Baldwin 6301 mortise body is the different animal you want.
18) I want keypad or card access on a mortise door instead of keys - what replaces a mechanical lever lockset?
The Omnia 12043 is a mechanical mortise lever lockset. For credential-based access on a mortise prep, the Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes in classroom function for doors 1-5/8 inch to 1-7/8 inch thick, the Dormakaba E-Plex E5086 is a Grade 1 electronic pushbutton and card mortise lock, and the Schlage LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and a 3 hour fire rating. The Accentra NTM623-NR is a nexTouch Series mortise lock with a capacitive touchscreen keypad and cylinder override for sites that want a key fallback.
19) What is the alternative to the Omnia 12043 for a bed or bath door that only needs privacy?
The Omnia 12043 comes in a privacy function with a lever. If a Grade 1 privacy mortise lock is called for, 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 thick, and the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with a deadbolt for 1-3/4 inch doors. The Schlage CO-100-MS-40-KP is a Grade 1 heavy duty standalone electronic mortise lock in privacy function with a keypad reader for 1-3/4 inch doors.
20) Is there a simpler mortise option if the door only needs to latch and never lock?
The Omnia 12043 is sold in a passage function among its lever options. Where a non-keyed passage mortise latch is all that is required, the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, and the Falcon MA101 is a Grade 1 heavy-duty mortise passage lock in the MA Series with field reversible operation and a fire rating. The Hager 3810S is a Grade 1 passage mortise lock with rose trim and a 2-3/4 inch backset, and the 3810E is the same passage function with an escutcheon instead of a rose.
21) What is the difference between an Omnia 12043 double cylinder mortise lockset and a Sargent 4874 mortise deadbolt?
The Omnia 12043 is a mortise lever lockset available in a double cylinder function, so the lever and the locking come as one assembly. The Sargent 4874 is a double cylinder mortise deadbolt in the 4870 Series with a 2-3/4 inch backset - a deadbolt only, with no lever operation, so it is used alongside separate door trim rather than in place of a complete lockset.
22) Can I key the Omnia 12043 units in a building alike or on a master system?
The keyed functions on the Omnia 12043, standard, storeroom, classroom, double cylinder and panic-proof, all operate from a cylinder, so the keying decision is made at the cylinder rather than the lockset. Ordering the same function across a run of unit doors keeps the operation consistent, and the levers and plates match across every function, keyed or not, so a building mixing entry, privacy and passage still reads as one set.
23) Is satin stainless steel the only finish on the Omnia 12043 mortise lever set?
Satin stainless, US32D, is the finish on the Omnia 12043. That is the same finish family as most commercial lever hardware, so it matches brushed stainless closers, push plates and hinges already on a building without a colour mismatch. Function, handing and backset are the choices you make; the finish is fixed.
24) Which dummy mortise trim should I order to match a working lever lockset on a pair of doors?
The Omnia 12043 is sold in single dummy and pair dummy functions, so the inactive leaf can carry the same lever appearance as the working one. If the look wanted is a knob or a specific Emtek design, the Emtek 3102 Memphis, 3104 Hamilton, 3106 Manhattan and 3019 Brisbane are all mortise entrance locksets in dummy function, with Brisbane in brass.
