Omnia 566TD/238F.PA.5 – Frequently Asked Questions

1) Will the Omnia 566 glass knob latchset fit my existing door with a 2-3/8 inch backset bore?
Yes. The 566 glass knob latchset is built on a 2-3/8 inch backset with a full lip strike, so it drops into standard residential bored prep. Knobs are 2-3/8 inch diameter with a 2-1/2 inch projection off the face of the door, so allow that clearance where the door swings against a wall or an adjacent casing.
2) What is the difference between the Passage, Privacy and Single Dummy versions of the Omnia 566?
Three functions are offered. Passage latches the door but never locks, which is what you want on a hall, closet or office door. Privacy locks by a spindle mechanism in the inside rose with an emergency release on the outside rose, which is the bed and bath function. Single Dummy is a non-operating knob on one side only, with no latch at all, used on a door held shut by a ball catch or roller catch. Order by function, not by trying to convert one into another later.
3) Can I use the Omnia 566 glass knob on a commercial office or apartment corridor door?
No. The 566 is a residential-duty glass knob latchset and carries no commercial grade rating, so it does not belong on a corridor, stair or other code-driven opening. For those, go to a graded cylindrical knob lock such as the Schlage D10S Grade 1 passage or the Corbin Russwin CK4310 Grade 1 passage/closet lock. Inside an apartment unit, on bedroom, bath and closet doors, the 566 is in its element.
4) What is the closest equivalent to an Omnia 566 glass knob privacy set from another brand?
For a decorative residential privacy knob on the same 2-3/8 inch backset and full lip strike, the Baldwin Estate 5000 Baltimore knob with 5148 rose is a privacy lock built to a 2-3/8 inch backset with a full lip strike, matching the Omnia 566 door prep directly. The Baldwin Estate 5077 Bethpage privacy knob with R027 rose is another privacy/bed/bath option in the same decorative family. The difference is the knob material: the Omnia 566 uses glass knobs on a solid brass substrate, while the Baldwin sets use the Baltimore and Bethpage cast knob designs.
5) What should I use instead of an Omnia 566 on a commercial opening that needs an ANSI grade?
The Omnia 566 is a residential knob latchset. For an opening that has to carry a stated ANSI/BHMA grade, the Schlage D10S passage latch is a Grade 1 heavy duty cylindrical knob lock, and the Corbin Russwin CK4310 passage/closet lock is Grade 1 with a 1-3/8 inch to 2 inch door thickness range. For a Grade 2 medium duty passage with a fire rating, the Falcon W101 is a Grade 2 cylindrical knob lock with a fire rating on a 2-3/4 inch backset. Note the Falcon W101 uses a 2-3/4 inch backset, so it does not drop into a door bored for the Omnia 566 2-3/8 inch backset.
6) I need a keyed knob on the same door style as the Omnia 566 glass knob. What are my options?
The Omnia 566 is offered in passage, privacy with emergency release, and single dummy functions, so a keyed opening needs a different set. Decorative keyed knobs include the Deltana 6112 St. Thomas entry knob and the Deltana 6901 Portland entry knob, both with a 1-3/8 inch to 1-3/4 inch or wider door thickness range, and the Deltana 3381 Egg knob entry, which fits 1-3/8 inch to 2 inch doors. On the production side, the Kwikset 400P Polo keyed entry knob is a Grade 3 entrance knob for 1-3/8 inch to 1-3/4 inch doors, and the Callan Edgewood is a Grade 2 entrance knobset.
7) What is a decorative alternative to the Omnia 566 single dummy knob?
The Omnia 566 single dummy mounts thru-bolt or surface. Comparable decorative dummies include the Emtek Classic Brass Crystal knobsets in Georgetown and Providence, both dummy function and supplied as a pair, and the Emtek Arts and Crafts Hammered Egg dummy pair. For a plainer dummy, the Schlage A170 is a Grade 2 single dummy trim for 1-3/8 inch to 1-7/8 inch doors, the BEST 6K single dummy trim is Grade 2 medium duty, and the Bravura Biloxi round trim dummy is Grade 2. Note the Emtek sets are pairs, covering both faces, while the Omnia 566 single dummy is one side.
8) Are Emtek Porcelain knobs a substitute for the Omnia 566 glass knob latchset?
No. The Emtek Porcelain knobs with threaded rod are supplied as two knobs per set on a threaded rod, so they are replacement knobs rather than a complete latchset. The Omnia 566 is a latchset that includes the latch on a 2-3/8 inch backset with full lip and a rose, in passage, privacy, or single dummy function. If the door already has a working latch and only the knobs are being changed, the Emtek porcelain knobs address that; if the latch is being replaced too, they do not.
9) The door is thicker than 1-3/4 inches. Is the Omnia 566 still the right knobset?
For a thicker interior door, the sets that state the widest ranges are the Corbin Russwin CK4310 passage/closet lock and CK4851 entrance/office lock at 1-3/8 inch to 2 inch, the Falcon X101 Grade 1 passage knobset at 1-3/8 inch to 2-1/4 inch, and the Deltana 6171 Round knob entry and 3381 Egg knob entry at 1-3/8 inch to 2 inch. The Deltana sets keep a decorative cast knob; the Corbin Russwin and Falcon sets are graded commercial knobsets, with the Falcon X101 taking an interchangeable core.
10) What replaces an Omnia 566 privacy knob on a storeroom or utility door that needs to stay locked?
The Omnia 566 privacy function locks by a spindle mechanism on the inside rose with an emergency release outside, which is a bathroom and bedroom arrangement rather than a secured door. For a storeroom, the Sargent 6G04 is a Grade 2 standard duty storeroom/closet knob lock with a single cylinder, and the Sargent 8XG04 is a Grade 1 heavy duty storeroom/closet single cylinder knob lock on a 2-3/4 inch backset. The BEST 8K Series is a Grade 1 heavy duty single cylinder entrance function knob lock. The 2-3/4 inch backset on the Sargent 8XG04 differs from the Omnia 566 2-3/8 inch bore.
11) Which rose shape should I pick for the Omnia 566, and what size is each one?
Five rose shapes, and the footprint decides it on a narrow stile or a door with existing wear marks. Traditional is 2-5/8 inch diameter, Modern is 2-5/8 inch diameter, Arched is 2-5/8 inch wide by 3-1/4 inch high, Rectangular is 2-5/8 inch wide by 3 inch high, and Square is 2-9/16 inch square. The two round roses cover the least area; Arched and Rectangular are the ones that will hide an older rectangular escutcheon shadow.
12) Do the Omnia 566 knobs come in a finish that matches the rest of my brass hardware?
Seven finishes are offered: Polished Brass, Satin Brass, Antique Brass, Black Oil-Rubbed, Polished Chrome Plated, Polished Nickel Plated and Satin Nickel Plated. Because the substrate is solid brass rather than plated zinc, the brass finishes wear the way the rest of a solid brass set in the house will.
13) I have a door that stays shut with a ball catch. Do I need a full latchset or just a knob?
Just the knob. Order the 566 in Single Dummy, which is a fixed knob with no latch and no working spindle, mounted either thru-bolt or on the surface. It is the right call for closet doors and French door leaves that a catch already holds. If you need both leaves trimmed, order two. A cross-brand alternative in a dummy knob is the Emtek Classic Brass Crystal Georgetown dummy, which ships as a pair.
14) What else could I buy instead of the Omnia 566 glass knob for a period interior door?
The closest look from another brand we carry is Emtek's Classic Brass Crystal knobsets, offered with the Georgetown and Providence knobs, and Emtek's Porcelain knobs with threaded rod if you want porcelain rather than glass. Baldwin's Estate line runs solid brass but in metal knob designs, such as the 5077 Bethpage privacy knob on an R027 rose. The 566 is the one of these that gives you a choice of five rose shapes and three functions on the same knob.
15) Does the Omnia 566 privacy knob let you get into a bathroom if someone is locked in?
Yes. The privacy version locks from the inside rose and has an emergency release on the outside rose, so a parent or a property manager can open the door from the corridor side without tools or removing the knob. That is the function to order for bedrooms and baths. Passage has no lock at all, and Single Dummy does not even carry a latch.
16) Can I standardize a whole apartment or renovation on the Omnia 566 across passage, privacy and dummy doors?
That is what the range is built for. One knob and one rose shape carries across Passage, Privacy and Single Dummy in the same finish, so bedroom, bath, closet and French doors all read identically. Specify the same rose shape and finish on every line of the order, and vary only the function per opening. Entry doors are the exception, since the 566 is a non-keyed residential latchset.
17) What is a simpler alternative to the Omnia 566 for closet and hall doors in a rental unit?
For hall and closet doors where the glass knob is not required, the Pamex FTF Baron knob lockset in passage function is a Grade 3 set for 1-3/8 inch to 1-3/4 inch doors, and the Bravura Albany with round trim is a Grade 2 passage knobset. The Kwikset 200P Polo passage knob ships with a 6AL latch and RCS round corner strike. The Omnia 566 differs in substrate and trim: it is solid brass with glass knobs and five rose shapes, including arched and square.
18) Can I use a Sargent 78-2875 or 28C knob trim in place of an Omnia 566?
No. The Sargent 78-2875 is an outside knob only in the 7800 Series, and the Sargent 28C-KNOB is exit device trim with knob and rose for 1-3/4 inch doors. Both are trim that mounts to an exit device rather than standalone latchsets. The Imperial USA ED-BKL580 is likewise knob trim in the ED-500 Series. The Omnia 566 is a self-contained latchset for a standard bored door prep on a 2-3/8 inch backset.
19) I want one product family to cover passage, privacy, and dummy across a whole apartment interior. How does the Omnia 566 compare to alternatives?
The Omnia 566 covers passage, privacy with emergency release, and single dummy in one family, across seven finishes and five rose shapes, so the interior doors match. Among the alternatives, the Dexter C2000 Series spans passage, privacy, entry/office, and classroom knob functions, all Grade 2 for 1-3/8 inch to 1-3/4 inch doors, and the Pamex FTF Baron family covers passage, privacy, and entrance/office at Grade 3 on the same door thickness range. The Dexter and Pamex families add keyed functions the Omnia 566 does not offer; the Omnia 566 offers the glass knob and rose shape choice.
20) Is there a keyless combination knob that can go on an interior door instead of an Omnia 566?
The Lockey 3830 is a mechanical keyless combination knob lock with an auto-locking passage function for doors 1 3/16 inch to 2 inch thick. It controls access by code with no key, where the Omnia 566 passage function has no locking at all and the privacy function locks only from inside with an emergency release. The Lockey 3830 suits a door where entry needs to be restricted without issuing keys; the Omnia 566 suits doors where the glass knob appearance is the point.
21) Is an Arrow MK01 or RK01 a drop-in for an Omnia 566 passage set?
They are both passage/hall/closet cylindrical knob locks at Grade 2 for 1-3/8 inch to 1-3/4 inch doors, so they serve the same passage function on a standard bored door. The Arrow MK01 is from the MK Series and the RK01 is an RK Series ball knob. What differs is the appearance: the Omnia 566 uses a 2-3/8 inch diameter glass knob on a solid brass substrate with a choice of five rose shapes, where the Arrow sets are plain metal knobs.
22) Is the Omnia 566 solid brass or brass-plated?
Solid brass substrate, not a plated pot-metal knob. That matters on a lever-free glass knob because the spindle and rose carry the load every time the door is used, and it is why the brass finishes hold up rather than wearing through to a base metal.
