Omnia 458TD/238F.PR.10B – Frequently Asked Questions

1) Is the Omnia 458 privacy knob suitable for a commercial building or apartment corridor doors?
The 458/PR is a residential-duty knobset, right for bedroom, bath, powder room and home office doors, including unit interiors in multi-family. For corridor, classroom or other traffic where an ANSI/BHMA grade is on the spec, look at a graded cylindrical lock instead: the Dexter C2000 privacy knob is Grade 2, and the Cal-Royal BER20 privacy knob is Grade 3.
2) Can you unlock an Omnia 458 privacy knob from the outside if a kid locks the bathroom door?
Yes. The privacy block locks from the inside only, and there is an emergency release on the outside knob so the door can be opened from the hall without tools or a key. That is the whole point of a bed/bath function: privacy while occupied, no lockout.
3) What do I have to specify when ordering the Omnia 458 privacy knobset?
Three choices. Finish, from Polished Brass, Satin Brass, Polished Chrome Plated, Polished Nickel Plated, Satin Nickel Plated, Black Oil-Rubbed and Tuscan Bronze. Rose shape, from Traditional, Arched, Modern, Rectangular and Square. And strike, either a full lip strike or a T strike. Nothing else is keyed or handed, so those three settle the order.
4) Full lip strike or T strike, which one do I need for my door frame?
Match what is already in the jamb. A T strike is the small rectangular plate that mortises into a flat wood jamb, and it is the usual swap when you are replacing residential hardware in a house. The full lip strike wraps the lip further to guide the latch in and pull the door tight, which helps on doors that have settled or sit slightly proud. The 458/PR is orderable either way, so pull the old strike first and order to the cutout you already have.
5) My door is bored for a 2-3/4 inch backset. Does the Omnia 458/PR fit, or do I need a different knob?
The Omnia 458/PR is built on a 2-3/8 inch backset. For a 2-3/4 inch bore, the Falcon W101 Grade 2 cylindrical knob lock is a passage/closet latch with a 2-3/4 inch backset, and the Sargent 8XG04 Grade 1 storeroom/closet knob lock uses a 2-3/4 inch backset as well. If the opening needs to work either way, the Schlage Residential F500 Plymouth with Georgian knob combo pack ships with adjustable backsets and dual strikes for doors 1-3/8 inch to 1-3/4 inch thick.
6) The Omnia 458/PR is a privacy knob. What do I use on the hall and closet doors in the same house so the knobs match in style?
The 458/PR handles the bed and bath openings in privacy function. For hall and closet doors that need no lock, passage knobs in comparable traditional styling include the Baldwin Estate 5011 Colonial Passage Knob with 5058 Rose and the Baldwin Estate 5000 Baltimore 2 inch knob with 5048 rose, which uses the same 2-3/8 inch backset and a full lip strike. The Bravura Albany and Bravura Lynchburg round-trim passage knobsets are Grade 2 passage alternatives. Matching the rose shape and finish across the two functions is what keeps the set looking uniform.
7) What is a direct alternative to the Omnia 458/PR privacy knob for a bedroom or bath door?
The Omnia 458/PR is a privacy/bed/bath knob latchset with a 2-3/8 inch backset in solid brass. Two other knobs carry the same privacy/bed/bath function: the Deltana 6112 St. Thomas Knob Privacy, which fits doors 1-3/8 inch to 2 inch thick, and the Dexter C2000 Series privacy cylindrical ball knob, a Grade 2 non-keyed knob for doors 1-3/8 inch to 1-3/4 inch. The Omnia is finished in solid brass with a choice of rose shapes, while the Dexter is a ball-knob design carrying an ANSI Grade 2 rating.
8) Which privacy knob is the closest match to a Baldwin Estate privacy knob with a full lip strike?
The Baldwin Estate 5000 Baltimore 2 inch knob with 5148 rose is a privacy lock with a 2-3/8 inch backset and full lip strike, and the Baldwin Estate 5077 Bethpage with R027 rose is a privacy/bed/bath knob. The Omnia 458/PR is also a privacy latchset built on a 2-3/8 inch backset, offered with a full lip strike or a T strike, and its knob measures 2 inch diameter with 2-1/2 inch projection on a 2-5/8 inch rose. The Omnia adds a choice of arched, modern, rectangular, square, or traditional rose, where the Baldwin models are supplied with their own specific rose.
9) My door is thicker than standard. Will a residential privacy knob still work, or do I need something else?
The Omnia 458/PR is a residential privacy latchset. Where a door runs thicker than a typical residential slab, the Deltana 6112 St. Thomas Knob Privacy is rated for doors 1-3/8 inch to 2 inch thick. On the commercial side, the Corbin Russwin CK4310 passage knob and the CK4851 entrance/office knob both cover 1-3/8 inch to 2 inch, and the Falcon X101 Grade 1 passage knobset goes to 2-1/4 inch. Confirm the actual slab thickness before ordering, because those wider ranges come with different functions than privacy.
10) Can I use the Omnia 458/PR on a commercial corridor or a fire-rated door?
The Omnia 458/PR is a residential privacy latchset in solid brass. For commercial openings, the knob locks that carry a fire rating are the Falcon W101 Grade 2 cylindrical knob lock in passage/closet function with a 2-3/4 inch backset and the Falcon X101 heavy duty Grade 1 passage knobset with interchangeable core. Heavy duty Grade 1 knob locks in other functions include the Sargent 8XG04 storeroom/closet lock with a 2-3/4 inch backset, the Schlage D10S Grade 1 passage latch, and the BEST 8K Series entrance function single cylinder knob lock.
11) What looks like a substitute for a privacy knob but will not lock the bathroom door?
Dummy knobs are the common mix-up. The BEST 6K Series single dummy trim, the Schlage A170 single dummy trim, the Cal-Royal BA40 dummy knob, the Bravura Biloxi dummy knobset, and the Emtek Hammered Egg, Georgetown, and Providence dummy pairs all carry a dummy function, meaning they are fixed trim with no latch and no locking. Passage knobs such as the Arrow MK01, Arrow RK01, and Pamex FTF in passage function do throw a latch but have no privacy lock. The Omnia 458/PR carries the privacy/bed/bath function with an interior privacy block and emergency release from outside.
12) The door needs a key, not a privacy lock. What knob do I order instead?
The Omnia 458/PR is privacy function, locked from inside with no key. Keyed knob options include the Cal-Royal BER00 Grade 3 entrance/office knob with a Kwikset keyway, the Pamex FTF Baron in entrance/office function at Grade 3, the Kwikset 400P-CP Polo keyed entry knob at Grade 3 for doors 1-3/8 inch to 1-3/4 inch, and the Master Lock BC Series Grade 3 biscuit knob keyed entry. For heavier openings the Dexter C2000 entry/office ball knob is Grade 2 and the Corbin Russwin CK4851 entrance/office knob uses a conventional cylinder.
13) How far does the Omnia 458 knob stick out from the door, and how big is the rose?
The knob is 2 inches in diameter with a 2-1/2 inch projection off the face of the door, on a 2-5/8 inch traditional rose. Worth checking if the door swings back against a wall, a vanity, or another door in a tight bath, since that projection is what hits first.
14) Is the Omnia 458 knob solid brass or plated pot metal?
Solid brass throughout, which is why it holds up to daily bathroom use and resists corrosion in a humid room better than plated zinc. The plated finishes (polished chrome, polished nickel, satin nickel) are plating over that brass body, while polished and satin brass are the brass itself.
15) What is a cheaper privacy knob than the Omnia 458 for a rental turnover?
If solid brass and the rose styling aren't the point, the Pamex FTF Baron privacy knob is a Grade 3 lockset for 1-3/8 to 1-3/4 inch doors, and the Cal-Royal BER20 privacy knob is Grade 3 with brass trim over the same thickness range. Deltana's 6112 St. Thomas privacy knob is the closer match if you want decorative styling, covering 1-3/8 to 2 inch doors.
16) Does the Omnia 458 privacy knob have to be ordered handed left or right?
No handing to call out. It's a cylindrical bored knobset, so the same set works on a left or right hand door. What you do need to get right is the backset (2-3/8 inches) and the strike style, since those are what the door and jamb prep dictate.
17) Is there a simpler privacy knob than the Omnia 458/PR for turnover units where solid brass is more than the job needs?
The Omnia 458/PR is solid brass and offered across polished brass, satin brass, polished and satin nickel plated, polished chrome plated, black oil-rubbed, and Tuscan bronze. Where the specification is lighter, the Cal-Royal BER20 is a Grade 3 privacy knob lock with brass trim for doors 1-3/8 inch to 1-3/4 inch, and the Pamex FTF Baron privacy knob lockset is Grade 3 over the same thickness range. Both hold the privacy/bed/bath function the bedroom and bath doors need.
18) What knob should I use on a school or office door where the Omnia 458/PR privacy function is not appropriate?
The 458/PR is a residential privacy latchset for bed and bath openings. Institutional functions come from other knobs: the Dexter C2000 Series classroom ball knob is Grade 2 and keyed for doors 1-3/8 inch to 1-3/4 inch, the Sargent 6G04 is a Grade 2 storeroom/closet knob lock with a single cylinder, and the Sargent 8XG04 is the Grade 1 heavy duty storeroom equivalent. For office doors, the Corbin Russwin CK4851 covers entrance/office at Grade 1 for doors 1-3/8 inch to 2 inch.
19) How does the Omnia 458/PR differ from a Deltana or Sure-Loc knob of similar traditional styling?
The Omnia 458/PR is a privacy/bed/bath knob latchset in solid brass on a 2-3/8 inch backset, with a 2 inch knob, 2-1/2 inch projection, and a 2-5/8 inch traditional rose, plus arched, modern, rectangular, square, and traditional rose shapes and a full lip or T strike. Deltana's traditional-styled knobs in the same family run to entry function, including the 3381 Egg Knob Entry, the 6171 Round Knob Entry, and the 6901 Portland Knob Entry, while the Deltana 6112 St. Thomas is the privacy one. Sure-Loc offers the Arapaho knob and the Modern Bergen round knob as style alternatives.
20) Is there a keyless combination knob I can use instead of a privacy knob on an interior door?
The Lockey 3830 is a mechanical keyless combination knob lock with an auto-locking passage function, fitting doors 1 3/16 inch to 2 inch thick. It is a code-entry device rather than a bed and bath privacy lock, so it does not offer the interior privacy block and outside emergency release that the Omnia 458/PR uses on bedroom and bathroom doors.
21) Can a knob like the Omnia 458/PR be used on a door with an exit device?
No. Exit device openings take trim made for the device, not a standalone cylindrical latchset. The Sargent 28C-KNOB is exit device trim with knob and rose in entrance function for 1-3/4 inch doors, the Sargent 78-2875 is an outside knob only with B design, and the Imperial USA ED-BKL580 is knob trim in storeroom function for the ED-500 series. The Omnia 458/PR is a self-contained cylindrical privacy latchset with its own latch and strike.
22) Can I get an Omnia 458 privacy knob with a square rose to match modern trim?
Yes. The 458 privacy knobset offers five rose shapes, Square, Rectangular, Arched, Modern and Traditional, so the same 2 inch knob can be dressed to match either classic or squared-off trim in the rest of the house.
23) Is the Omnia 458 a knob-only trim or a complete lockset with the latch?
It's a complete latchset: knobs both sides, roses, the latch, and a strike, ordered as either a full lip or T strike. You are not adding a separate latch. Compare that with dummy trim like the BEST 6K single dummy or the Schlage A170, which are knob-only with no latch behind them and are used on doors that don't latch at all.
