Omnia D11055/A3 – Frequently Asked Questions

1) What is the difference between the standard and double cylinder versions of the Omnia D11055?
The standard version is keyed on the outside with a thumbturn inside. The double cylinder version takes a key on both faces, so nobody can retract the deadbolt from inside without a key. Double cylinder is what people specify on doors with glass beside or in the door, where an arm reaching through the glass could otherwise turn the inside thumbturn. Check your local egress code first, since keyed-both-sides deadbolts are restricted in some jurisdictions on a dwelling exit door.
2) Is the Omnia D11055 a commercial-rated lockset for an apartment building corridor?
The D11055 is a residential lockset. It suits individual dwelling unit entries, townhouse and condo doors, and single-family entries, including unit doors in a multi-family building. For a corridor, stairwell, or any opening in a commercial building carrying real traffic or a fire rating, this is the wrong family of product and you want a Grade 1 or Grade 2 commercial cylindrical or mortise lock instead.
3) Does the 2-1/2 inch projection on the Omnia D11055 clear a storm door or a door casing?
The lever and plate stand 2-1/2 inches off the door face. That is the number to check against your storm door or screen door: if the storm door panel or its closer bracket sits closer than that to the primary door, the lever will strike it. Same check on the interior side against a tight casing or an adjacent return wall, since a lever needs swing clearance the whole way down, not just at rest. The plate footprint itself is 10-5/8 inches by 2-3/8 inches, so it also needs a stile wide enough to take 2-3/8 inches of plate without running off the edge of the rail or into the glass stop.
4) I want a knob instead of a lever on my entry door. What do I use in place of the Omnia D11055?
The Omnia D11055 is built around a lever handle, so every function it offers is lever-operated. Where a knob is wanted on the entry door, the Emtek 5302 Modern Rectangular Single Point Lockset with Round Knobs is a single cylinder set in the Round series with an Entry product function. Note that a knob is not an ADA-friendly operator the way a lever is, which matters if the opening falls under an accessibility requirement.
5) Is the Emtek 5302 single point lockset a drop-in substitute for an Omnia D11055 double cylinder set?
It is not the same function. The Omnia D11055 double cylinder variant is keyed on both sides, which is what gets specified on a door with glass beside or within it. The Emtek 5302 Modern Rectangular Single Point Lockset with Hanover Lever and the Emtek 5302 with Round Knobs are both single cylinder sets carrying an Entry function, so they are keyed outside and operated by hand inside. A double cylinder requirement is not met by either of those; stay with the D11055 double cylinder variant for that opening.
6) What are the dummy versions of the Omnia D11055 for, and do they lock?
The dummy versions do not lock and have no working latch. Single dummy is one surface-mounted plate and lever for a door that stays closed by a ball catch or magnetic catch, or for the inactive leaf of a pair. Pair dummy is two of them, one on each face, for a door you want to pull from either side. People order them so a closet, pantry, or inactive door matches the working entry set on the rest of the openings. If you need it to actually secure the door, order the standard or double cylinder function instead.
7) I need the deadbolt and lever to match on several doors in a house. What finishes does the Omnia D11055 come in?
Three finishes across the whole D11055 range: polished brass, polished chrome plated, and shaded bronze. All three are available in every function, standard, double cylinder, single dummy, and pair dummy, so you can run one finish across your entry doors and your closet or pantry dummies and have them read the same. Polished chrome is the cooler match to nickel and chrome plumbing trim; shaded bronze is the darker, aged look; polished brass is the warm traditional one.
8) Should I use a sideplate lockset like the Omnia D11055 or separate rosettes with a standalone deadbolt?
A sideplate set puts the deadbolt and the lever on one continuous escutcheon plate, so the two holes are tied to a fixed 5-1/2 inch center to center relationship and the plate hides the door prep between them. Choose it when you want that unified traditional look, or when you are covering up an old door face with existing marks or mismatched holes. Separate rose trim with a standalone deadbolt is the more flexible choice: you can set the deadbolt at whatever height you like above the lever, and you can swap either piece independently later. The sideplate commits you to the spacing.
9) What else could I put on a residential entry door instead of the Omnia D11055 sideplate set?
If the sideplate footprint is too much plate for the door, or your stile is too narrow to take 2-3/8 inches of width, look at Emtek's single point locksets. The Emtek 5302 Modern Rectangular is a brass tubular key-in-lever set, and the same 5302 platform is offered with the Hanover lever or with round knobs, both as single cylinder entry function. Those are single point sets, so lever and cylinder in one unit rather than a lever plus a separate deadbolt on a shared plate, and they read modern rather than traditional. The Emtek Helios lever is the same idea on the Modern Brass Tubular body.
10) Can I use one Omnia D11055 set on a pair of French doors?
You need two orders for a pair. The active leaf takes the standard or double cylinder function in the correct hand, and the inactive leaf takes the pair dummy or single dummy so the trim matches across both doors. Order both leaves in the same finish, and confirm each leaf's stile can carry a 2-3/8 inch wide plate with 2-1/2 inches of projection without the levers colliding at the meeting stiles when both doors are closed.
11) What is the difference between the Omnia D11055 and the Emtek Helios lever lockset for a contemporary house?
The Omnia D11055 is a traditional collection sideplate lockset, meant to sit with classic door hardware, and it is chosen by finish, function, handing and backset. The Emtek Modern Brass Tubular Single Point Lockset with Helios Lever is in the Helios series with an Entry product function and a modern brass tubular build. On a contemporary opening the Helios set is the closer style match; where the rest of the doors in the house already carry traditional trim, the D11055 keeps the set consistent.
12) Is the Omnia D11055 lever easier to operate than a knob for an accessible entrance?
It is a lever, not a knob, which is the operable-without-grasping shape people specify for accessibility on a residence. That is the practical advantage: an occupant with limited hand strength can push the lever down with a forearm or a closed fist. Note it is a residential-duty lockset, so for an opening that has to satisfy an actual code-enforced accessible route in a commercial or public building you should be specifying commercial-grade hardware.
13) Will the Omnia D11055 hold up on a coastal or high-humidity exterior door?
The lockset is stainless steel, which is the reason it goes on exterior entries: it resists the corrosion that eats plated pot metal at the door edge. Bear in mind the finish is a separate matter from the base metal. Polished brass and polished chrome plated are bright plated finishes that will want regular wiping in salt air, while shaded bronze is a living finish that darkens and changes with exposure by design.
