Omnia 53059/AD – Frequently Asked Questions

1) Which functions does the Omnia 53059 Ornate lockset come in, and which one do I want for an office or a closet?
Four functions: Standard, Panic-Proof, Passage, and Single Dummy. Passage is the one for a closet or a hall door that never locks, both knobs always turn. Standard is the keyed everyday entry. Panic-Proof lets the inside knob retract the latch and the deadbolt together in one motion, which is what you want on a door someone has to get out of in a hurry. Single Dummy is a surface-mounted non-operating knob for an inactive leaf, no latch at all.
2) How much space do I need on the door face for the Omnia 53059 escutcheon plates?
The plates measure 13-7/8 inches overall length by 2-7/8 inches wide, with a 2-1/8 inch projection off the face of the door. On a narrow-stile or glass-front door check the stile against that 2-7/8 inch width first, and check the 2-1/8 inch projection against anything the knob could hit, an adjacent wall, a pull, a door in a tight return.
3) Can I use the Omnia 53059 on a bathroom or bedroom door that needs to lock from inside?
No. The four functions are Standard, Panic-Proof, Passage, and Single Dummy, and none of them is a privacy set with an inside turn and emergency outside release. For a mortise privacy function look at the Cal-Royal NM8440, a Grade 1 privacy mortise lockset with deadbolt, or the Hager 3840S privacy mortise lock on a 2-3/4 inch backset for doors 1-3/4 to 2 inches thick. Neither will match the Ornate decorative plate, so on a job where appearance rules, use the 53059 Passage on the bath door and add a separate privacy bolt.
4) I need a mortise knob lock for a decorative entry, what else could I look at besides the Omnia 53059?
For a similar look in a mortise entry knob, Baldwin's 6301 knob-by-knob entry/apartment mortise lock body runs a 2-1/2 inch backset for doors 1-3/4 inches and over, and the 6310 knob-by-knob entry/storeroom body is a 2-1/2 inch backset for doors 1-3/8 inches and over, so the 6310 is the one for a thinner older door. Marks USA 21AC and 22AC are ornamental-iron mortise locks with a round knob, both listed at a 1 inch door thickness, which puts them on gate and iron doors rather than a standard wood or hollow metal opening. The Omnia is the only one of these that ships with the Ornate decorative plates as part of the set.
5) Will the Omnia 53059 work on a classroom or storeroom door where the outside stays locked?
It will not do a true classroom or storeroom function. The 53059 offers Standard, Panic-Proof, Passage, and Single Dummy only. For classroom, the Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset for 1-3/4 inch doors, and the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset with auxiliary deadlatch, also 1-3/4 inch. For storeroom, the Cal-Royal NM8080 is Grade 1 with an interchangeable core option, and the Accentra 8805FL is a Grade 1 storeroom mortise lock in the 8800 Series. Use the 53059 where the decorative face matters and the function is entry, passage or dummy.
6) I need a passage mortise lock for a hall or closet door instead of the ornate Omnia knob set - what should I order?
The Omnia 53059 does offer a passage function, and it is a knob set with decorative plates 13-7/8 inches long. If the opening calls for a plainer passage mortise lock, 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 with field reversible operation and a fire rating. Hager offers the same function two ways in the 3800 Series: the 3810E with escutcheon and the 3810S with rose, both passage with a 2-3/4 inch backset and a 1-3/4 to 2-1/2 inch door thickness range. The Falcon MA101's field reversible operation means one part covers both hands, where the Omnia 53059 is ordered left handed or right handed.
7) My spec calls for an ANSI/BHMA Grade 1 mortise lock - what mortise locksets carry a stated Grade 1?
Several mortise locksets state Grade 1 directly. The Accentra 8805FL is Grade 1 storeroom in the 8800 Series with an Arcadia lever. The Corbin Russwin ML2003 is a Grade 1 mortise classroom lockset in the ML2000 Series for 1-3/4 inch doors. Cal-Royal's NM series covers four functions at Grade 1 for 1-3/4 inch doors: NM8050 office/entrance with auxiliary deadlatch, NM8070 classroom, NM8080 storeroom with interchangeable core option, and NM8440 privacy with deadbolt. Sargent 7925 is Grade 1 heavy duty in the 7900 Series with corridor/dormitory function, rose trim, and a single cylinder deadbolt. The Omnia 53059 is a solid brass mortise knob lockset with decorative plates, so the choice between them is a spec question rather than a prep question.
8) The door is prepped for a 2-3/4 inch backset - which mortise locks match that without redrilling?
The Omnia 53059 is ordered with either a 2-1/2 inch or 2-3/4 inch backset, so the 2-3/4 inch option drops into that prep. Among other mortise locks on a 2-3/4 inch backset: Hager's 3800 Series 3810E passage with escutcheon, 3810S passage with rose, 3840S privacy, and 3850E office with lever and escutcheon non-keyed. The Sargent 4874 double cylinder mortise deadbolt is also a 2-3/4 inch backset. The Baldwin 6301 and 6310 lock bodies are 2-1/2 inch backset, which matches the other Omnia 53059 option instead. Confirm door thickness alongside the backset: the Hager 3840S is listed at 1-3/4 to 2 inch where the 3810E, 3810S, and 3850E run 1-3/4 to 2-1/2 inch.
9) What finishes does the Omnia 53059 Ornate knob lockset come in?
Four: Siena Brass, Venetian Nickel, Florentine Brass, and Etruscan Bronze. All four are offered across every function, so a building running Passage sets on the interiors and Standard keyed sets on the entries can hold one finish throughout. These are Omnia's own hand-applied finish names rather than BHMA numbers, so match them by name against Omnia hardware already in the building, not by a 605 or 613 equivalent.
10) Is the Omnia 53059 solid brass all the way through or brass plated?
Solid brass construction, not plated steel or zinc. That matters two ways on a commercial job: the finish wears into the material instead of off it on a high-touch knob, and brass holds up in a humid or coastal corridor where a plated part blisters. It is a knob, not a lever, so it is not the part for an opening that has to meet an ADA operable-hardware requirement.
11) What is the difference between the Single Dummy and the Passage version of the Omnia 53059?
Passage has a working latch, both knobs turn and retract it, so the door stays shut until someone pushes it. Single Dummy has no latch and no mortise body at all, it is a fixed knob on the Ornate plate that mounts to the door face for pulling. Order Single Dummy for the inactive leaf of a pair, or a false door front where you only need the hardware to match. Order Passage for a real closet or corridor door. Both need the handing selected so the knob and plate read correctly on the face.
12) I am standardizing hardware across a building, can I mix Omnia 53059 functions on different doors and keep them looking the same?
Yes, and that is the practical reason to spec it. Every one of the four functions, Standard, Panic-Proof, Passage and Single Dummy, is available in all four Ornate finishes with the same 13-7/8 by 2-7/8 inch plate and 2-1/8 inch projection. So a corridor of passage sets, keyed entries at the tenant doors and dummy knobs on the inactive leaves all read as one set of hardware from the hallway. Handing and backset are still per-door choices, so survey the openings before you build the order.
13) Is a mortise lockset like the Omnia 53059 the right choice, or should I use a cylindrical lock?
Mortise is right when the door already has a rectangular pocket cut into its edge, or when you are cutting new prep on a solid door and want the heavier body and the option of a deadbolt in the same case. Cylindrical goes in a round cross-bore and is far easier to retrofit into an existing bored door, the Schlage PC10 Grade 1 passage cylindrical lock is that route. Do not try to convert one to the other by hand, a mortise pocket cannot accept a cylindrical lock and boring a mortise-prepped door usually means replacing the door.
14) What is a decorative mortise dummy alternative to the Omnia 53059 single dummy?
The Omnia 53059 is offered in a single dummy function across its four finishes, with the same 13-7/8 inch decorative plates as the working functions. For decorative dummy mortise trim from another line, Emtek offers four designs as mortise entrance locksets in dummy function: the 3019 Brisbane in brass, the 3102 Memphis, the 3104 Hamilton, and the 3106 Manhattan. The distinction is the operating trim: the Omnia 53059 dummy is a knob set, and the Emtek 3019 Brisbane is a brass set in the Brisbane series. On the commercial side, the Schlage L0170 is a Grade 1 heavy duty non-keyed mortise half dummy lever trim in the L Series for 1-3/4 inch doors - half dummy, so a single side rather than a matched pair.
15) Can I use an electronic mortise lock in place of the Omnia 53059 if I need keypad or credential access?
The Omnia 53059 is a mechanical mortise knob lockset in solid brass with four function choices, so credential access means moving to a different lock. In the same mortise pocket, the Alarm Lock DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes and classroom function, for 1-5/8 to 1-7/8 inch doors. The Schlage CO-100 is a Grade 1 heavy duty standalone electronic mortise lock with a keypad reader in privacy function for 1-3/4 inch doors. For RFID, the TownSteel FME-2000 is a Grade 1 heavy duty classroom mortise lockset with RFID for 1-3/4 inch doors, and the Dormakaba LX-I-M002 Saffire is an electronic RFID mortise lockset with BLE mobile access at BHMA Grade 2. Note the door thickness differences: the DL3500CR tops out at 1-7/8 inch where the CO-100 and FME-2000 are specified at 1-3/4 inch.
16) Is the Sargent 4874 mortise deadbolt a substitute for the Omnia 53059 mortise lockset?
No - they do different jobs in the door. 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 operating trim to retract a latch. The Omnia 53059 is a mortise knob lockset with decorative plates and a knob on each side, ordered in standard, panic-proof, passage, or single dummy function. Two other items that also read as mortise but are not locksets: the Kaba Ilco 185 Series is a deadbolt function mortise lock with no handing, and the Sargent 130KB is a standard duty mortise thumbturn in the 8200 Series, which is trim rather than a lock. If the opening needs both latching and a turning knob, the 53059 covers it; if it needs a separate bolt above the lock, the 4874 is the deadbolt.
17) I want a lever instead of the Omnia 53059 knob on a mortise entrance door - what are my options?
The Omnia 53059 is a knob lockset, so a lever means a different part. Baldwin offers the same lock bodies in lever trim: the 6301LS is the entrance/apartment lever by lever version on a 2-1/2 inch backset for 1-3/4 inch and over doors, and the 6310190RRLS is the entrance/storeroom lever by lever on a 2-1/2 inch backset, right hand reverse, for 1-3/8 inch and over. Both share the 2-1/2 inch backset with the Omnia 53059's 2-1/2 inch option. Note that the 6310190RRLS is handed right hand reverse as ordered, while the Omnia 53059 is specified left handed or right handed at the time of order. For a Grade 1 lever mortise entrance lock, the Accentra 8805FL is storeroom function in the 8800 Series with an Arcadia lever.
18) Can I order just the mortise lock body and reuse my existing knobs instead of the full Omnia 53059 set?
The Omnia 53059 ships as a complete lockset with its decorative plates included, so it is bought as a set rather than as a bare body. If only the lock body is wanted, the BEST 45H Series is a heavy duty mortise lock body in public entrance function with field reversible operation, and the 45HCA Series heavy duty mortise lockbody comes in intruder function in the 40H Series. Baldwin's 6301 and 6310 are also supplied as mortise lock bodies on a 2-1/2 inch backset, with entrance/apartment and entrance/storeroom functions respectively. Trim-only parts exist too: the Sargent 130W is a mortise thumbturn with a round backplate in the 7800 Series.
19) I need a privacy function for a restroom or bedroom door - what mortise lock covers that?
The Omnia 53059 is offered in standard, panic-proof, passage, and single dummy functions, so a privacy opening calls for a different lock. The Cal-Royal NM8440 is a Grade 1 heavy duty privacy mortise lockset with a deadbolt for 1-3/4 inch doors. The Hager 3840S in the 3800 Series is a Grade 1 privacy mortise lock with a 2-3/4 inch backset and a 1-3/4 to 2 inch door thickness range, which matches the Omnia 53059's 2-3/4 inch backset option. For electronic privacy, the Schlage CO-100 is a Grade 1 heavy duty standalone electronic mortise lock with privacy function and keypad reader for 1-3/4 inch doors. The NM8440 includes a deadbolt where the 3840S is specified as a privacy mortise lock.
20) Which mortise locks state a fire rating if my opening is a rated door?
For a rated opening, look to the peers that state a fire rating: the Falcon MA101, a Grade 1 heavy-duty mortise passage lock with field reversible operation, states a fire rating, as does the Falcon MESC600DT dummy escutcheon lever trim for M9900 Series exit devices. Schlage Electronics states hours directly - the LEMD-GRW, a Grade 1 ENGAGE Series wireless mortise lock with a 125kHz proximity reader and Greenwich trim, is 3 hours, and the LEBMB-ADD mobile-enabled mortise lock is 3 hours at Grade 2 for 1-3/4 inch doors. The Omnia 53059 is a solid brass ornate mortise knob lockset chosen for commercial door systems, so on a rated opening confirm the assembly requirement against the rated peers above.
21) I need an access-controlled or electrified mortise lock wired to my panel - what replaces a mechanical mortise lockset?
The Omnia 53059 is a mechanical mortise knob lockset, so panel-controlled access means an electrified body. The BEST 45HW Series is a heavy duty wired electromechanical mortise lock with 12V/24V operation. The Command Access ML190 Series is a heavy-duty motorized mortise lock in storeroom function with field selectable fail safe or fail secure operation and 24VDC power. The Schlage L9092EU with 03A trim is a heavy duty electric lock/unlock outside lever mortise lock, keyed outside, with request to exit on 12/24VDC, corridor function for 1-3/4 inch doors. The ML190's field selectable EL/EU operation means one lock covers either fail state, where the L9092EU is ordered as the EU configuration.
