Omnia 12036/A26D – Frequently Asked Questions

1) How much room does the Omnia 12036 lockset take up on the door face?
The plate runs 10-9/16 inches overall by 2-3/8 inches wide, and the lever projects 2-1/2 inches off the face. That 2-3/8 inch width is the number that matters on a narrow stile: if the flat of your stile is under about 2-1/2 inches the plate will run onto the glass stop or the panel molding. The 2-1/2 inch projection is what you check against an adjacent wall, a door stop, or a second leaf on a pair.
2) What functions does the Omnia 12036 mortise lockset come in?
Nine functions: passage, privacy, classroom, storeroom, standard, double cylinder, panic-proof, single dummy and pair dummy. That covers a whole house off one plate design. Bedroom and bath take privacy, closets and halls take passage, the entry takes standard or double cylinder, and dummies handle the inactive leaf of a pair or a fixed closet door where you only want the look of the lever.
3) Is the Omnia 12036 mortise lockset suitable for a commercial or school door?
No. The 12036 is a residential lockset, and it should not be specified where a commercial opening needs a graded lock. For a school or office door, look at a Grade 1 mortise set instead: the Corbin Russwin ML2003 classroom lockset or the Cal-Royal NM8070 classroom lockset, both Grade 1 for 1-3/4 inch doors, or the Cal-Royal NM8080 storeroom lockset with an interchangeable core option.
4) What is a Grade 1 mortise lever lockset alternative to the Omnia 12036 for a commercial opening?
The Omnia 12036 is a solid brass mortise lever lockset built for residential use. For a commercial opening, the Cal-Royal NM8050 is a heavy duty Grade 1 office/entrance mortise lockset with an auxiliary deadlatch for 1-3/4 inch doors, and the Cal-Royal NM8080 is a heavy duty Grade 1 storeroom mortise lockset with an interchangeable core option, also for 1-3/4 inch doors. The Accentra 8805FL is a Grade 1 storeroom mortise lock with the Arcadia lever from the 8800 Series. Any of these carries an ANSI/BHMA Grade 1 rating the Omnia 12036 is not built to, which matters where a spec calls out Grade 1 by name.
5) The Omnia 12036 comes in 2-1/2 inch and 2-3/4 inch backset. What other mortise locks match those backsets?
The Omnia 12036 is ordered with either a 2-1/2 inch or a 2-3/4 inch backset. On the 2-1/2 inch side, the Baldwin 6301 is an entry/apartment mortise lock body with a 2-1/2 inch backset in knob by knob, and the 6301LS is the same entry/apartment lock body in lever by lever, both for doors 1-3/4 inch and over; the Baldwin 6310 is an entry/storeroom mortise lock body at 2-1/2 inch backset for doors 1-3/8 inch and over. On the 2-3/4 inch side, the Hager 3810S is a 3800 Series Grade 1 passage mortise lock with rose at 2-3/4 inch backset and the 3810E is the same passage lock with escutcheon, both for 1-3/4 inch to 2-1/2 inch doors, and the Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset.
6) The Omnia 12036 is handed left or right. Which comparable mortise locks avoid handing at the time of order?
The Omnia 12036 is ordered as left handed or right handed, so the hand has to be confirmed at the door before the order goes in. If you would rather not commit, the BEST 45H Series heavy duty mortise lock body in public entrance function is field reversible, and the Falcon MA101 Grade 1 heavy duty mortise passage lock is field reversible as well. The Kaba Ilco 185 Series mortise lock is a deadbolt function with no handing. The Baldwin 6310190RRLS, by contrast, is a right hand reverse lever by lever entry/storeroom mortise lock, so it is handed like the Omnia.
7) Which products look like substitutes for the Omnia 12036 but will not replace it?
The Omnia 12036 is a complete mortise lever lockset with plates, so a like-for-like replacement has to include both the lock body and the lever trim. Several mortise-family parts are not that. The Sargent 130KB and 130W are mortise thumbturns, trim pieces only. The Schlage L0170 is half dummy trim in the L Series, non-keyed, with no latching mechanism, and the Falcon MESC600DT is dummy escutcheon lever trim for M9900 Series exit devices. The BEST 45HCA Series intruder unit and the BEST 45H public entrance unit are lock bodies without trim. The Kaba Ilco BR Series is a glass door bottom rail lock for a different opening type entirely.
8) What mortise lock has a fire rating where the Omnia 12036 does not carry one?
The Omnia 12036 is a residential mortise lever lockset. On a rated opening, the Schlage Electronics LEMD-GRW is a Grade 1 ENGAGE Series wireless mortise lock with a 3 hour fire rating, 125kHz proximity reader and Greenwich trim, and the LEBMB-ADD is a Grade 2 mobile-enabled mortise lock with a 3 hour fire rating covering privacy, office and apartment functions for 1-3/4 inch doors. For a mechanical option, the Falcon MA101 Grade 1 heavy duty mortise passage lock in the MA Series is fire rated.
9) Can I use one lever design across every door in the house with the Omnia 12036?
That is what the 12036 range is built for. The same 10-9/16 inch plate and lever is available in passage, privacy, classroom, storeroom, standard, double cylinder, panic-proof, single dummy and pair dummy, in five finishes. Pick the function per opening and the finish once, and every door reads the same from the hallway. The dummy versions matter for that: they carry no latch at all, so a fixed or inactive leaf still matches its neighbors.
10) What is the difference between the Omnia 12036 and a Baldwin 6301 mortise lock body?
Different scopes. The 12036 is a complete lockset, lock plus lever plus plates, in one order. The Baldwin 6301 is a lock body only, entry/apartment function on a 2-1/2 inch backset for doors 1-3/4 inches and over, and you buy trim separately; the 6301LS is the lever-by-lever version of it. If you want a finished decorative opening in one part number, the 12036 is the one. If you are replacing a failed lock body behind trim you are keeping, the Baldwin body is the right shape of purchase.
11) I need a decorative mortise lever set for an entry door but I only want the look on the inactive leaf. What do I order?
Order the 12036 in a dummy function. Single dummy covers one leaf, pair dummy covers both faces of an inactive leaf. Dummy trim has no latch and no mortise lock body, so the door is held by a flush bolt or roller catch, not by the lever. Emtek runs the same idea in its own styling if you want a different lever shape: the 3102 Memphis, 3104 Hamilton, 3106 Manhattan and 3019 Brisbane are all mortise entrance sets in dummy function.
12) Does the Omnia 12036 come with the plates, or do I buy trim separately?
Plates are included. The 12036 ships as a complete mortise lockset with the plates and lever, so what arrives is the whole visible assembly at the ordered finish. You still specify hand, backset and function, and keyed functions such as standard and double cylinder need cylinders and keys sorted to whatever the rest of the house is keyed to.
13) Should I put a double cylinder mortise lock on a house entry door?
The 12036 offers a double cylinder function, which means a key is needed from inside as well as outside. It stops someone reaching through adjacent glass and turning a thumbturn, which is why it gets specified on glazed entries. The tradeoff is egress: nobody leaves without a key in the door. Many residential codes restrict it on a required exit. Where you want the glass protection without that problem, the standard keyed function with an inside turn is the safer pick.
14) What is the difference between the classroom and storeroom function on the Omnia 12036?
Both are keyed on the outside, and they differ in how the outside lever behaves. Storeroom keeps the outside lever locked at all times, so it is key-only entry and the door secures itself every time it shuts. Classroom lets a key unlock the outside lever and leave it unlocked until someone keys it back, so a room can be held open through the day. Inside lever always retracts the latch on both. For a home office or a storage room, storeroom; for a room you want to switch between open and secure, classroom.
15) Is there a decorative mortise lever lockset comparable to the Omnia 12036 in solid brass?
The Omnia 12036 is a solid brass mortise lever lockset offered in Polished Brass, Black Oil-Rubbed, Polished Chrome Plated, Satin Chrome Plated, and Satin Nickel Plated. On the decorative side, the Emtek 3019 Brisbane is a brass mortise entrance lockset in dummy function, and Emtek also builds the 3102 Memphis, 3104 Hamilton, and 3106 Manhattan mortise entrance locksets in dummy function. The Emtek units named here are dummy trim, so they mount on an inactive leaf and do not latch; the Omnia 12036 is a working lockset in functions including passage, privacy, and storeroom.
16) I need keypad or card access on the door instead of a keyed Omnia 12036. What mortise locks do that?
The Omnia 12036 is a mechanical mortise lever lockset with keyed functions such as storeroom and double cylinder, so access is by key. For credential-based access in the same mortise prep, the Alarm Lock DL3500CR is a Trilogy electronic mortise lock, Grade 1, classroom function, with 300 user codes for doors 1-5/8 inch to 1-7/8 inch. The Schlage CO-100 is a standalone electronic mortise lock with a keypad reader in privacy function, Grade 1 heavy duty for 1-3/4 inch doors. The TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors, and the Dormakaba Saffire LX-I-M002 is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2.
17) For a bathroom or bedroom door, is there a simpler alternative to the Omnia 12036 privacy lockset?
The Omnia 12036 is available in privacy function as part of a solid brass mortise lever lockset with plates. If the opening only needs the privacy function without the decorative brass suite, the Hager 3840S is a 3800 Series Grade 1 privacy mortise lock with a 2-3/4 inch backset for doors 1-3/4 inch to 2 inch, and the Cal-Royal NM8440 is a heavy duty Grade 1 privacy/bed/bath mortise lockset with deadbolt for 1-3/4 inch doors.
18) I only need passage function. What is a straightforward passage mortise lock next to the Omnia 12036?
The Omnia 12036 is offered in passage function among its function choices. Where only passage is needed, the Schlage PM010 is a Grade 1 passage latch mortise lock, non-keyed, 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 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, which is the one to specify in behavioral health openings. Note the Schlage PC10 is a Grade 1 passage lock with rose but is cylindrical, not mortise, so it will not drop into a mortise pocket.
19) The Omnia 12036 offers a double cylinder function. What other mortise double cylinder options exist?
The Omnia 12036 is available in double cylinder function as a solid brass mortise lever lockset. The Sargent 4874 is a double cylinder mortise deadbolt in the 4870 Series with a 2-3/4 inch backset, which is a deadbolt only rather than a latching lockset. The Marks USA 21AC is an entrance double cylinder Unilock ornamental iron mortise lock with a round knob for 1 inch doors, and the 22AC is an entrance double cylinder ornamental iron mortise lock with round knob, also for 1 inch doors, both suited to narrow ornamental iron gates and doors rather than a standard wood door.
20) Can the Omnia 12036 be tied into an access control system, or do I need a different mortise lock?
The Omnia 12036 is a mechanical mortise lever lockset, so it operates by lever and key with no electrified option. For a door that has to lock or unlock from a system, the Command Access ML190 is a heavy duty motorized mortise lock in storeroom function with field selectable fail safe or fail secure operation on 24VDC, and the BEST 45HW Series is a heavy duty wired electromechanical mortise lock with 12V or 24V operation. The Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock, keyed outside, with request to exit and 12/24VDC for 1-3/4 inch doors.
21) What finishes is the Omnia 12036 solid brass lockset available in?
Five: polished brass, black oil-rubbed, polished chrome plated, satin chrome plated, and satin nickel plated. The body is solid brass throughout, so on the plated finishes you have brass under the plating rather than a zinc casting. If you are matching hinges and stops already in the building, polished brass and satin nickel are the two that most often line up with existing residential trim.
22) Will the Omnia 12036 lever work for someone who cannot grip a knob?
It is a lever, not a knob, so it operates with a closed fist, a forearm or an elbow, which is the reason levers get specified in aging-in-place and accessible residential work. If you are matching an existing house, note that swapping a knob set for this changes the prep as well as the look, since the 12036 is a mortise lockset on a 10-9/16 inch plate.
