Omnia D12042/A26D – Frequently Asked Questions

1) Will the Omnia D12042 lever lockset fit my existing door prep, or do I need to drill new holes?
The D12042 is a sideplate set with 5-1/2 inch center to center spacing between the lever and the deadbolt, so the two bores in your door have to sit at that spacing. It's a standard residential prep, but it is not the two-piece arrangement you get with a separate knob and deadbolt at whatever spacing the last installer chose. Measure center of the lever bore to center of the deadbolt bore before you order. Backset is chosen at order time, 2-3/8 inch or 2-3/4 inch, so match that to your existing bore as well.
2) Do I have to specify handing when ordering the Omnia D12042 deadbolt lever lockset?
Yes, handing is a required choice on the D12042, left handed or right handed. Stand outside the door: if the hinges are on your left it's a left hand door, hinges on the right is right hand. A lever set with sideplates is not field-reversible the way a plain knob often is, so getting this right on the order matters. Backset is the other required choice, 2-3/8 or 2-3/4 inch.
3) Which backset do I need for the Omnia D12042, 2-3/8 or 2-3/4 inch?
Measure from the edge of the door to the center of the existing bore. 2-3/8 inch is the common residential backset and 2-3/4 inch turns up on heavier or wider entry doors. Both are offered on the D12042 and backset is a required selection at order time, so you cannot leave it blank. If the door is new and unbored, pick the backset that suits the stile you have to work with and prep to it.
4) What is the difference between the Omnia D12042 double cylinder version and an Emtek single cylinder entry lockset?
The Omnia D12042 is ordered in a double cylinder function as well as a standard function, so the double cylinder version is keyed on both faces rather than turned by a thumbturn inside. The Emtek 5302 with the Helios lever and the Emtek 5302 with the Hanover lever are both single cylinder entry locksets, keyed outside only. Double cylinder is what gets specified next to glass, where an inside turn could be reached through a light; single cylinder is what most residential codes expect on a primary egress door, so check the local requirement for the opening before choosing.
5) What is the closest Emtek equivalent to the Omnia D12042 lever lockset for a residential entry door?
The Emtek 5302 Modern Rectangular Single Point Lockset with the Hanover lever is the nearest Emtek match in concept: it is a single point lockset in the Hanover series with an Entry function, so like the Omnia D12042 it puts a lever and keyed entry security on one residential opening. The difference is in the plate shape and how the two are ordered - the D12042 is a sideplate design in solid brass at 10 9/16 inch overall length with 5-1/2 inch center to center spacing, and it is ordered by handing (left or right) and backset (2-3/8 inch or 2-3/4 inch). If your door prep is already cut for a long sideplate, confirm the plate footprint before crossing to the Emtek.
6) I want a knob instead of a lever on my entry door - what should I use in place of the Omnia D12042?
The Emtek 5302 Modern Rectangular Single Point Lockset with Round Knobs is the knob alternative; it is a Round series single point lockset with an Entry function. The Omnia D12042 is a lever product - its handle type is lever throughout, which is what gives it the push-down operation people specify for accessibility. Choose the Emtek round knob version when the design calls for a knob, and stay with the D12042 when lever operation is the requirement.
7) Is the Emtek 5302 a drop-in substitute for the Omnia D12042, or does the door prep change?
Treat it as a different prep, not a drop-in. The Emtek 5302 Modern Rectangular is a brass tubular key-in-knob/lever lockset - a tubular bore with a rectangular rosette. The Omnia D12042 is a sideplate lockset measuring 10 9/16 inch overall length by 2 3/8 inch wide with 5-1/2 inch center to center spacing between the lever and the deadbolt, so the door carries a long plate over two bores at a fixed spacing. Swapping between the two means the visible plate area and the hole pattern both change, so verify the existing door face before committing either direction.
8) How much does the Omnia D12042 lever stick out from the door face?
Projection is 2-3/4 inches off the face of the door, and the sideplate itself runs 10 9/16 inches long by 2 3/8 inches wide. That projection is the number to check if the door swings back against a wall, a cabinet, or a second door in a tight entry, and the plate length matters on a narrow stile or a door with a light beside the lock edge.
9) What are the dummy versions of the Omnia D12042 for?
Single dummy and pair dummy are non-operating trim. There is no latch and no deadbolt behind them; the lever is fixed and the plate just mounts to the face of the door. Single dummy is for one leaf, typically a closet or a false door held by a ball catch or a roller. Pair dummy gives you the trim on both faces of the same door. Buyers use these on the inactive leaf of a double door so it matches the working set beside it. If you need the door to actually lock, order the standard or double cylinder function.
10) What finishes does the Omnia D12042 come in, and can I match it across a whole building?
Five finishes: polished brass (US3), oil-rubbed bronze (US10B), satin nickel plated (US15), polished chrome plated (US26), and satin chrome plated (US26D). Every finish is offered in all four functions, standard, double cylinder, single dummy, and pair dummy, so you can run one look across entry doors and closet trim in a building without a finish break. Oil-rubbed bronze is a living finish and will change tone with handling over time.
11) Should I use a sideplate lockset like the Omnia D12042 or a separate lever and deadbolt?
A sideplate set ties the lever and the deadbolt into one continuous plate on each face, so the two bores are covered by a single piece of brass and the alignment is fixed by the plate rather than by the installer. Separate trim gives you freedom in spacing and lets you swap the deadbolt without touching the lever, but you see two rosettes and any misalignment between them. Go with the sideplate when the entry door is the visual centrepiece and the prep is at the standard 5-1/2 inch spacing; go with separate pieces when your existing bore spacing is nonstandard.
12) What else could I use instead of the Omnia D12042 if I want a single point entry lockset?
Emtek's single point locksets are the closest alternatives ZenSupply carries. The Emtek 5302 Modern Rectangular with the Hanover lever is a single cylinder entry set on a brass tubular chassis, and the 5302 with the Helios lever is the same single cylinder entry arrangement in the Helios trim. If you want a knob rather than a lever, the 5302 Modern Rectangular comes with round knobs, also single cylinder entry. The practical difference from the Omnia D12042 is that these Emtek sets are single point, so lever and deadbolt function are combined in one unit rather than spread across a plate with a separate deadbolt bore.
13) Is the Omnia D12042 lever lockset suitable for a commercial building or apartment corridor doors?
The D12042 is a residential-rated set. It's built for entry doors on single family homes, townhouses, condominiums, and individual apartment unit doors. For corridor doors, stairwells, or anything in a commercial building that needs a cycle-rated commercial chassis, this is not the set to specify. Property managers do use it inside multi-family units and on renovation work where the look of solid brass trim is the point.
14) I need matching hardware on an interior or closet door that does not need to lock - what pairs with the Omnia D12042?
Stay within the Omnia D12042 itself: it is ordered in single dummy and pair dummy functions alongside the keyed ones, in the same solid brass sideplate form and the same finishes, so a non-latching door gets the identical plate and lever as the entry door beside it. The Emtek 5302 comparables are entry-function locksets - the Hanover, Round and Helios versions are all listed as Entry - so they do not cover the dummy application.
15) For a run of units where I want one lever style across every door, does the Omnia D12042 or the Emtek 5302 family give more consistency?
Both approach it differently. The Emtek 5302 platform carries several lever and knob styles on the same single point lockset - Hanover, Helios and the Round knob all sit on the 5302 body - so you standardize on one lock and vary the handle. The Omnia D12042 standardizes the other way: one lever and one solid brass sideplate across five finishes, Polished Brass, Satin Nickel Plated, Polished Chrome Plated, Satin Chrome Plated and Oil-Rubbed Bronze, with keyed, double cylinder and dummy functions all in that same appearance. Pick the Emtek route if different doors want different handle shapes, and the D12042 if every door should read identically.
16) Is the Omnia D12042 solid brass all the way through or just plated?
Solid brass construction, with the plated finishes applied over that brass body rather than over a zinc or steel casting. That matters on an exterior entry door where a plated pot-metal lever eventually corrodes at the edges. Polished brass is the unplated finish; the nickel and chrome options are plate over the same brass base.
