Omnia 25430/A3 – Frequently Asked Questions

1) Which Omnia 25430 function should I order for a front entry door?
For a standard keyed entry, order the Standard function. If the door has glass beside or within it and you want the inside to require a key as well, the Double Cylinder version locks from both sides with no thumbturn. On a rental or an exterior door that must stay locked from outside while always opening from inside, order Storeroom. Panic-Proof is the choice where the inside knob must retract the latch and the deadbolt in one motion for egress.
2) How much clearance do I need on the door face for the Omnia 25430 knob plates?
The plate assembly runs 10-5/8 inches overall by 2-3/8 inches wide, and the knob projects 2-3/4 inches off the face. Measure the flat area of the stile before ordering: a narrow rail or a raised panel starting less than 2-3/8 inches in from the door edge will not seat the plate flat. The 2-3/4 inch projection also matters where the door swings back against a wall or against an adjacent door in a corner, since the knob hits before the door face does.
3) Is the Omnia 25430 mortise lockset rated for commercial or residential use?
Residential. The 25430 is a solid brass beaded knob lockset built for houses, period renovations, and custom residential work. If you are specifying for a school, office, or any opening on a commercial drawing, look at a Grade 1 mortise lock instead, such as the Corbin Russwin ML2003 classroom mortise lockset or the Cal-Royal NM8050 office and entrance mortise lockset, both of which are listed Grade 1.
4) Can I use the Omnia 25430 on a door that already has a bored hole instead of a mortise pocket?
No. This is a mortise lockset, meaning the lock case sits in a rectangular pocket routed into the edge of the door, not in a round cross bore. A door prepped for a cylindrical lock has to be re-prepped by a shop or a router jig to take it. If the door is already bored for a tubular lock and you want to keep it that way, a cylindrical passage or entry lock, such as the Schlage PC10 passage cylindrical lock, drops into the existing prep instead.
5) What is a comparable mortise knob lockset to the Omnia 25430 if I want a knob-by-knob entry function?
The Baldwin 6301 is a knob-by-knob entry/apartment mortise lock body with a 2-1/2 inch backset, and it fits doors 1-3/4 inch and over. The Omnia 25430 is a mortise beaded knob lockset with plates, ordered with a 2-1/2 inch or 2-3/4 inch backset and left or right handing. If the opening already takes a 2-1/2 inch backset knob mortise prep, both land in the same pocket; the difference is the 25430 comes as a complete set with knobs and plates in solid brass, where the Baldwin 6301 is the lock body itself.
6) I need a mortise storeroom lock for a commercial opening, not a residential one. What should I look at instead of the Omnia 25430?
The Omnia 25430 is built for residential use, in solid brass with a beaded knob and matching plates. For a commercial storeroom opening, 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. Both are levered rather than knobbed, which also matters if the opening has to meet an accessibility requirement.
7) The Omnia 25430 classroom function is on my list for a school corridor. Is it the right lock for that?
The Omnia 25430 does offer a classroom function, but it is a residential solid brass knob lockset. For a school corridor, the Cal-Royal NM8070 is a Grade 1 classroom mortise lockset for 1-3/4 inch doors with an auxiliary deadlatch, and the Corbin Russwin ML2003 is a Grade 1 classroom mortise lockset in the ML2000 Series for 1-3/4 inch doors. If the facility wants a visual indicator at the door, the Marks USA LA318GJ is a Grade 1 classroom security indicator mortise lockset with an ANSI strike and steel escutcheon measuring 8-1/2 inch by 2-3/4 inch by 7/16 inch.
8) Can I use a Sargent 4874 in place of the Omnia 25430 double cylinder?
Not as a like-for-like. The Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset in the 4870 Series - a deadbolt alone, with no knob or latch. The Omnia 25430 double cylinder is a complete beaded knob lockset with plates in solid brass. The 4874 is the right part when the door already has separate latching hardware and you are adding keyed security above it, not when the knob set itself has to be replaced.
9) Is the Schlage PC10 an alternative to the Omnia 25430?
They do not share a door prep. The Schlage PC10 is a Grade 1 non-keyed passage cylindrical lock with a rose for 1-3/4 inch doors - cylindrical, meaning a bored hole through the door face. The Omnia 25430 is a mortise lockset, which needs a pocket routed into the door edge. A door prepped for one will not take the other without rework, so the choice is driven by what is already cut into the door.
10) What mortise lock should I use instead of the Omnia 25430 on a thin ornamental iron door?
The Omnia 25430 is sized for standard residential doors. For a 1 inch ornamental iron door, the Marks USA 21AC is an entrance double cylinder Unilock ornamental iron mortise lock with a round knob for 1 inch doors, and the Marks USA 22AC is an entrance double cylinder ornamental iron mortise lock with a round knob, also for 1 inch doors. Both keep the round knob operation while fitting the narrow stile that a wood-door mortise set will not.
11) Is there a keypad or electronic version of the Omnia 25430 beaded knob lockset?
No, the 25430 is mechanical only, keyed and non-keyed functions with a knob. For keyless entry in a mortise pocket, the electronic options are separate products with their own trim: the Alarm Lock DL2700CR Trilogy T2 with classroom function, the Alarm Lock DL4500 electronic mortise deadbolt with keypad privacy, or the Schlage CO-100 standalone electronic mortise lock with keypad reader. None of those carry the traditional beaded knob styling.
12) What finishes does the Omnia 25430 knob lockset come in, and will they match my other hardware?
Three finishes: Polished Brass, Polished Chrome Plated, and Shaded Bronze. Polished Brass is the US3 equivalent and Polished Chrome the US26, so they coordinate with hinges and bath hardware specified in those standard codes. Shaded Bronze is a living finish look for period and traditional work. All three are available across every function, so a whole floor can be standardized on one finish and mixed functions.
13) Is the Omnia 25430 a complete lockset or just the lock body?
Complete set. The 25430 ships as a full mortise lockset with the beaded knobs and matching plates, so you are not sourcing trim separately. That is the difference between it and a bare lock body like the Baldwin 6301 knob-by-knob mortise lock body or the BEST 45H heavy duty mortise lock body, which are the lock case only and need trim specified on top.
14) I need a matching knob on a closet or a double door that does not latch. What do I order?
Single Dummy for one fixed knob on a non-latching door, and Pair Dummy where you need a knob on both faces of an inactive leaf. Both use the same beaded knob and plate as the working functions, so a set of double doors reads identically whether the leaf latches or not. Emtek makes mortise dummy sets too, like the 3104 Hamilton and 3106 Manhattan, but those are different knob patterns and will not match the beaded design.
15) Can I order the Omnia 25430 with levers instead of knobs for an accessible door?
The 25430 is a knob set only, beaded knob with matching plates. Knobs require grasping and twisting, so where an accessible lever is called for you need a different product. Lever mortise options include the Baldwin 6301LS entry and apartment lever-by-lever mortise lock body at 2-1/2 inch backset, or the Hager 3810E passage mortise lock with lever and escutcheon on a 2-3/4 inch backset.
16) Is there a simpler mortise option than the Omnia 25430 if the door only needs to latch?
The Omnia 25430 does come in a passage function, but if the trim style is not the point, the Schlage PM010 is a Grade 1 non-keyed passage latch mortise lock for 1-3/4 inch doors, and the Hager 3810S is a Grade 1 passage mortise lock with a rose and a 2-3/4 inch backset for doors 1-3/4 inch to 2-1/2 inch. The Falcon MA101 is a Grade 1 heavy duty mortise passage lock in the MA Series that is field reversible and fire rated. The Omnia route gets you solid brass and a beaded knob with matching plates; the others are non-keyed latch hardware without that trim treatment.
17) What is the closest match to the Omnia 25430 dummy if I want a period-styled brass mortise dummy from another brand?
Emtek offers several brass mortise entrance dummy locksets, each in its own style: the 3019 Brisbane, the 3102 Memphis, the 3104 Hamilton, and the 3106 Manhattan, all in a dummy function. The Omnia 25430 covers dummy applications too, in single dummy and pair dummy, in Polished Brass, Polished Chrome Plated, or Shaded Bronze with the traditional beaded knob. The choice between them is the design family rather than the mechanism.
18) I want keyless entry on the same opening. What replaces the Omnia 25430 if I go electronic?
The Omnia 25430 is a keyed mechanical mortise lockset. For keyless on a mortise prep, the Alarm Lock DL2700CR is a Trilogy T2 Grade 1 electronic mortise lock with classroom function and weatherproof design for doors 1-5/8 inch to 1-7/8 inch, and the DL3500CR is a Grade 1 Trilogy electronic mortise lock with 300 user codes and classroom function over the same thickness range. If the goal is a deadbolt rather than a latching set, the Alarm Lock DL4500 is a Grade 1 electronic mortise deadbolt with 2,000 user codes and a privacy keypad. Note the thickness ranges - a heavier door than 1-7/8 inch rules these out.
19) For a bathroom or bedroom door, how does the Omnia 25430 privacy function compare with other mortise privacy locks?
The Omnia 25430 privacy function is a solid brass beaded knob set with matching plates, available in Polished Brass, Polished Chrome Plated, and Shaded Bronze. 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, and the Cal-Royal NM8440 is a Grade 1 privacy mortise lockset with a deadbolt for 1-3/4 inch doors. The two peers are lever-oriented commercial privacy hardware; the 25430 is a knob set aimed at traditional residential doors.
20) Will a Schlage L0170 work as a substitute for the Omnia 25430?
Only for a dummy application, and the trim is different. The Schlage L0170 is a Grade 1 non-keyed mortise half dummy lever trim in the L Series for 1-3/4 inch doors - half dummy lever trim, so it is a pull on one face with no working mechanism. The Omnia 25430 offers single dummy and pair dummy in a beaded knob with plates, plus keyed and non-keyed functions from the same knob design. If the door needs an active latch or a key, the L0170 is not the part.
21) For an apartment building where I need one mortise design across entry and storeroom doors, how does the Omnia 25430 compare with Baldwin?
The Omnia 25430 carries standard, storeroom, classroom, privacy, passage, double cylinder, panic-proof, single dummy, and pair dummy functions on one beaded knob design in Polished Brass, Polished Chrome Plated, and Shaded Bronze. Baldwin splits it across bodies: the 6301 is entry/apartment knob by knob at a 2-1/2 inch backset for doors 1-3/4 inch and over, and the 6310 is entry/storeroom knob by knob at a 2-1/2 inch backset for doors 1-3/8 inch and over. Baldwin also offers the same two in lever form, the 6301LS and the 6310190RRLS right hand reverse.
22) I need a mortise lock with a deadbolt-only function. Does the Omnia 25430 do that, or is there a better part?
The Omnia 25430 is a knob lockset with plates, so the knob and trim come with it. For a deadbolt-only mortise part, the Kaba Ilco 185 Series is a mortise deadbolt with no handing, sold in a single pack, and the Sargent 4874 is a double cylinder mortise deadbolt with a 2-3/4 inch backset. The no-handing feature of the 185 Series is worth noting if you are stocking for a building where left and right openings are mixed, since the Omnia set is ordered left or right handed.
23) What material is the Omnia 25430 knob and plate, and how does it hold up outdoors?
Solid brass throughout, knobs and plates. Brass does not rust, which is why it holds up on an exterior entry where a plated steel set would blister at the edges. On the Shaded Bronze the surface will move with handling over time, which is the intended look on period work; Polished Brass and Polished Chrome hold their appearance longer under regular cleaning.
