Omnia TRADDBA34.38.10B – Frequently Asked Questions

1) Will the Omnia TRADDB auxiliary deadbolt fit a 1-3/8 inch door, or only a 1-3/4 inch door?
Both, but you order the thickness. The TRADDB is built as a thickness-specific kit rather than an adjustable one, so it comes in a 1-3/8 inch version and a 1-3/4 inch version, each in the same six finishes. Measure the door edge before you order; 1-3/4 is the standard on newer entry doors and 1-3/8 turns up on older interior and lightweight entry doors. Getting the wrong one means the turnpiece tailpiece and screws won't land right.
2) Is the Omnia TRADDB deadbolt keyed on both sides or key outside and thumbturn inside?
Key outside, thumbturn inside. The TRADDB is a single cylinder, cylinder x thumbturn function, so anyone inside can throw or retract the bolt by hand with no key. If you have glass within reach of the lock and want to stop someone breaking it and reaching the turn, you need a double cylinder deadbolt instead, keyed on both sides, like the Emtek 8323 Disc, the Baldwin Reserve Contemporary Round, or the Callan 210S.
3) Can I use the Omnia TRADDB deadbolt on apartment or office entry doors in a commercial building?
The TRADDB is a residential deadbolt, and Omnia rates it that way. It suits single-family entries, custom homes, and unit doors in multi-family housing. For a commercial opening, or anywhere a facility spec calls for a graded lock, go to a graded deadbolt instead: the Accentra D111 and the Dexter DB1000 are Grade 1 cylinder x thumbturn units rated 1-3/8 to 1-3/4 inch doors, and the Hager 3215 is a Grade 2 single cylinder with a 1 inch throw over the same thickness range.
4) What is an auxiliary deadbolt and do I still need a knob or lever with it?
An auxiliary deadbolt is a second, separate lock that goes above the main latch. It has no latchbolt of its own and won't hold the door closed, so you order it alongside a knobset, leverset, or handleset that does the latching. That is the whole point of the TRADDB: it adds a key-operated bolt to an opening whose primary lock is already there. If instead you want one bore doing both jobs, you're looking at an interconnected lock like the Falcon H2101, which combines an entrance lock and a single cylinder deadbolt.
5) What is the closest equivalent to the Omnia TRADDB auxiliary deadbolt if I need a keyed single cylinder deadbolt with a thumbturn inside?
The Omnia TRADDB is a cylinder x thumbturn deadbolt with a 2-3/8 inch backset in solid brass. For the same keyed-outside, turn-inside operation from another maker, the Accentra D111 is a Grade 1 single cylinder deadbolt with a 2-3/8 inch backset that covers 1-3/8 inch to 1-3/4 inch doors, and the Dexter DB1000 single cylinder deadbolt is Grade 1 cylinder x thumbturn covering 1-3/8 inch to 1-7/8 inch doors. Both operate the same way at the door; the Omnia is the one built in solid brass in the Traditional collection.
6) The Omnia TRADDB is a residential deadbolt. What should I use on a commercial opening that needs an ANSI Grade 1 deadbolt?
The Omnia TRADDB is built for residential applications. Where the spec calls for a Grade 1 deadbolt, the Cal-Royal CRB800 is a heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch, the Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock for 1-3/4 inch to 2-1/4 inch doors, and the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and a 6-pin cylinder for 1-3/8 inch to 1-3/4 inch doors. All three are keyed deadbolts; they carry the commercial grade rating the Omnia is not rated to.
7) I need a deadbolt keyed on both sides instead of a thumbturn. What are my options?
The Omnia TRADDB is keyed outside with a turnpiece inside, so it will not work where a key is required on both faces, such as a door with glass beside the lock. Double cylinder alternatives include the Hager 3214 Grade 2 deadbolt with a Schlage C keyway for 1-3/8 inch to 1-3/4 inch doors, the Dexter DB2000 double cylinder deadbolt at Grade 2 for the same thickness range, and the Design Hardware D1 Series Grade 1 double cylinder deadbolt for 1-3/4 inch doors. Check local egress code before specifying a double cylinder on an occupied exit door.
8) My doors have a 2-3/4 inch backset. The Omnia TRADDB is 2-3/8 inch - what deadbolt fits instead?
The Omnia TRADDB is prepped for a 2-3/8 inch backset. For a 2-3/4 inch bore, the Deltana CL200LA is a Grade 2 single cylinder deadbolt with a 2-3/4 inch backset, and the CL200LAIC is the same lock with an interchangeable core prep. If your fleet has both backsets, the Cal-Royal ED500 and Cal-Royal LSD are Grade 3 single cylinder deadbolts with an adjustable backset covering 1-3/8 inch to 1-3/4 inch doors, and the Brinks Raleigh E2401 has a 4-way adjustable backset.
9) What is a simpler option than the Omnia TRADDB if the door does not need to be keyed?
The Omnia TRADDB includes a keyed cylinder on the exterior. If the opening only needs to be secured from inside, the Arrow E60 is a Grade 2 non-keyed exit deadlock with a blank plate outside and a thumbturn inside, covering 1-3/8 inch to 1-3/4 inch doors. For a door with no through-bore on the outside face at all, the Callan 205S is a Grade 3 one-sided half-bore deadbolt. Neither can be opened with a key from the exterior the way the Omnia can.
10) My door is thicker than 1-3/4 inches. Will the Omnia TRADDB work, and what else should I look at?
The Omnia TRADDB is built for 1-3/8 inch and 1-3/4 inch doors. For a thicker stile, the Corbin Russwin DL3011 Grade 1 cylindrical deadlock covers 1-3/4 inch to 2-1/4 inch, the Deltana 7312KA2 double cylinder deadbolt is Grade 3 and covers 1-3/8 inch to 2 inch, and the Dexter DB1000 single cylinder deadbolt at Grade 1 covers 1-3/8 inch to 1-7/8 inch. The Corbin Russwin gives the widest range of the three.
11) How much does the Omnia TRADDB deadbolt stick out from the door face?
The exterior cylinder rose projects 9/16 inch off the face, and the interior turnpiece projects 1-3/8 inch. The rose is 2-5/8 inch in diameter. Those numbers matter when a storm door, a screen door, or a narrow entry trim sits close to the face, and when you are checking that the turnpiece clears an inswing door at a tight wall return.
12) What finishes does the Omnia TRADDB deadbolt come in, and will it match my existing Omnia levers?
Six orderable finishes: Polished Brass, Satin Brass, Black Oil-Rubbed, Polished Chrome, Polished Nickel Plated, and Satin Nickel. All six are offered in both the 1-3/8 and 1-3/4 inch door thickness. Because the trim is solid brass rather than plated zinc, the plated and living finishes wear the way the rest of the Omnia Traditional collection does, which is what you want when the deadbolt sits directly above a matching handleset.
13) Can I key the Omnia TRADDB deadbolt to match the other locks on the house?
The TRADDB ships as a keyed cylinder x turnpiece kit, so keying is decided by the cylinder that goes in it. Matching it to an existing set means matching keyway and keying at order time. If you are standardizing a portfolio around a facility keyway instead, a deadbolt built for an interchangeable core is the cleaner path, like the Deltana CL200LAIC, which is a Grade 2 single deadbolt supplied for an IC cylinder, or the Arrow E61 with SFIC prep less core.
14) I need a traditional round brass deadbolt but on a tighter budget, what else is close to the Omnia TRADDB?
Closest in look and function is the Bravura 310B Elite, a Grade 2 traditional round deadbolt with the same cylinder x thumbturn setup. The Emtek #11 Tuscany is the other direction, cast bronze traditional trim, also cylinder x thumbturn. Where the Omnia differs is the specifics it publishes: solid brass, a 2-5/8 inch rose, 9/16 inch exterior projection, and a fixed 2-3/8 inch backset, which is what you check against an existing bore.
15) Is the Omnia TRADDB a good match for a contemporary door, or is there a squarer looking deadbolt?
The Omnia TRADDB is a Traditional collection deadbolt with a 2-5/8 inch round rose. For contemporary trim with the same cylinder x thumbturn operation, the Bravura 310SC Elite is a Grade 2 contemporary square deadbolt and the 310RC Elite is the contemporary round version; the Bravura 910 rectangle deadbolt is a Grade 2 single cylinder with rectangular trim. The Brinks Mendocino E2402 is a contemporary square single cylinder deadbolt with a 4-way adjustable backset. All lock the same way; the difference is the shape of the trim at the door face.
16) Which of these deadbolts look like substitutes for the Omnia TRADDB but will not drop into the same bored door prep?
The Omnia TRADDB is a bored deadbolt on a 2-3/8 inch backset. Several deadbolts in the same family need a different door prep entirely: the Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch, the Dormakaba D900 is a small case mortise deadbolt, and the Codelocks CL200 is a surface mounted deadbolt with key override. The Arrow 460 is a mortise lock strike, not a lock at all. The Baldwin 8BR0618001 is a deadbolt spacer, a component rather than a complete deadbolt.
17) I want keypad or credential entry instead of a keyed deadbolt like the Omnia TRADDB. What replaces it?
The Omnia TRADDB is a mechanical deadbolt operated by key and turnpiece. Electronic replacements in the same deadbolt format include the Delaney KP400, a Grade 2 electronic deadbolt with a programmable remote, the Codelocks CL2200 electronic surface deadbolt in brushed steel, and the Codelocks CL2210 electronic mortise deadbolt. For multifamily credential systems, the Dormakaba Nova-D is an RFID multihousing smart electronic deadbolt and the Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override. Note that the surface and mortise versions do not use the same door prep as a bored deadbolt.
18) I want a solid brass deadbolt like the Omnia TRADDB in a decorative style. What else is cast in brass or bronze?
The Omnia TRADDB is a solid brass Traditional deadbolt with a 2-5/8 inch round rose. In the same decorative territory, the Emtek #11 Tuscany is a lost wax cast bronze deadbolt with cylinder x thumbturn operation, the Emtek 8323 Modern Disc deadbolt is brass in a double cylinder configuration, and the Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt. The Tuscany matches the Omnia on keyed-outside, turn-inside operation; the two Baldwin and Emtek double cylinder models take a key on both faces.
19) What deadbolt should I use on a classroom or institutional door where the Omnia TRADDB is meant for homes?
The Omnia TRADDB is a residential auxiliary deadbolt. On institutional openings, the Falcon D111 is a Grade 1 heavy duty classroom deadbolt with an adjustable backset and cylinder x thumbturn operation, the Falcon D211 is the Grade 2 medium duty classroom equivalent, and the Corbin Russwin DL3211 is a Grade 1 cylindrical deadlock for 1-3/4 inch doors. For facilities standardizing on one keyway, the Hager 3118 Grade 1 classroom deadbolt uses a Schlage C keyway with a 6-pin cylinder.
20) The Omnia TRADDB is an auxiliary deadbolt that mounts separately. What if I want the deadbolt and knob as one unit?
The Omnia TRADDB is a standalone auxiliary deadbolt installed above the latchset. If you would rather have one unit doing both jobs, the Falcon H2101 is a Grade 2 entrance interconnected lock with a single cylinder deadbolt, which combines the deadbolt and the latch trim in one assembly and retracts both with the inside lever. That changes the door prep, so it is a different bore pattern than adding an auxiliary deadbolt to an existing door.
21) Which deadbolts are the closest peers to the Omnia TRADDB at a lighter duty level for interior or low-traffic doors?
The Omnia TRADDB is a residential deadbolt with cylinder x thumbturn operation. At Grade 3, the Callan 200S is a single cylinder square trim deadbolt and the Cal-Royal LSD is a single cylinder deadbolt with an ADA ergonomic thumbturn covering 1-3/8 inch to 1-3/4 inch doors, which is worth noting if the turn has to be operable without tight grasping. At Grade 2, the Cal-Royal CB160 adds a tamper-resistant cylinder guard and the Callan 200S-G2 is a round trim single cylinder deadbolt.
22) Is a solid brass deadbolt worth it over a plated one on an exposed exterior door?
On a door that takes weather, brass is the substrate you want. The TRADDB is solid brass through the trim rather than plated pot metal, so surface wear and coastal air don't expose a different material underneath. On a covered porch or an interior-to-garage door the difference matters much less, and a graded utility deadbolt will serve just as well there.
