Omnia RECTDBA34.34.26D – Frequently Asked Questions

1) Will the Omnia RECTDB auxiliary deadbolt fit my door, and what backset do I need to order?
The RECTDB is built for 1-3/4 inch doors, the standard thickness on a residential entry or a light commercial opening. Backset is a choice you make at order time: 2-3/8 inch or 2-3/4 inch. Measure from the door edge to the center of the existing bolt hole and pick the one that matches. There is no adjustable backset here, so ordering the wrong one means the bolt won't line up with the prep.
2) I have a 1-3/8 inch door. Can I use the Omnia RECTDB deadbolt on it?
No. The RECTDB is a single-thickness deadbolt for 1-3/4 inch doors only, so a 1-3/8 inch door needs something with a range. The Dexter DB2000 single cylinder covers 1-3/8 to 1-3/4 inches, as does the Accentra D111 in Grade 1 and the Cal-Royal LSD. For an older interior door at 1-3/8 inches, one of those is the part to order.
3) What does single cylinder mean on the Omnia RECTDB, and can I get a key on both sides?
Key outside, thumbturn inside. The RECTDB is cylinder by thumbturn only, so anyone inside throws or retracts the bolt by hand without a key. That is what you want on most entries, and it is what fire escape thinking favors. If you need a key on both sides, say for a door with glass beside it, this is not the part. Double cylinder options include the Baldwin Reserve Contemporary Square deadbolt, the Emtek 8323 Modern Disc in brass, and the Callan 210S.
4) Is the Omnia RECTDB deadbolt rated for a commercial building or an apartment corridor door?
Omnia lists the RECTDB as residential. It suits entry doors on houses, condo and apartment unit doors, and light back-of-house use. For a corridor, stairwell, or anything that has to answer to a commercial spec, look at a graded deadbolt instead: the Cal-Royal CRB800 is heavy duty single cylinder, the Design Hardware D1 Series is Grade 1 extra heavy duty for 1-3/4 inch doors, and the Corbin Russwin DL3211 is a Grade 1 cylindrical deadlock for 1-3/4 inch doors.
5) What is the closest equivalent to the Omnia RECTDB if I need a single cylinder deadbolt with square trim?
The Bravura 310SC Elite is a Grade 2 contemporary square deadbolt with Cylinder x Thumbturn function, the same keyed-outside, turn-inside operation the Omnia RECTDB uses. The Callan Model 200S is another square trim single cylinder deadbolt, Grade 3, also Cylinder x Thumbturn. The Bravura Rectangle Deadbolt single cylinder is Grade 2 Cylinder x Thumbturn with rectangular trim, closest in shape to the RECTDB rectangular escutcheon.
6) I need a deadbolt with an ANSI grade for a spec-driven job - what takes the place of the Omnia RECTDB?
For a Grade 1 single cylinder deadbolt, the Accentra D111 is Cylinder x Thumbturn and fits doors 1-3/8 inch to 1-3/4 inch, and the Dexter DB1000 single cylinder is Grade 1 covering 1-3/8 inch to 1-7/8 inch. The Deltana CL200LM is a Grade 1 single cylinder deadbolt as well. Stepping to Grade 2, the Dexter DB2000 single cylinder covers 1-3/8 inch to 1-3/4 inch and the Arrow DBX61 is a Grade 2 single cylinder. All four run the same Cylinder x Thumbturn function as the Omnia RECTDB, so the keying and the user operation are unchanged.
7) The Omnia RECTDB is built for 1-3/4 inch doors - what single cylinder deadbolt should I use on a 1-3/8 inch door?
Several single cylinder deadbolts with Cylinder x Thumbturn function reach down to 1-3/8 inch: the Accentra D111 (1-3/8 inch to 1-3/4 inch), the Dexter DB2000 single cylinder (1-3/8 inch to 1-3/4 inch), the Hager 3215 (1-3/8 inch to 1-3/4 inch), and the Cal-Royal ED500 (1-3/8 inch to 1-3/4 inch, Grade 3, adjustable backset). The Deltana 7312KA2 spans 1-3/8 inch to 2 inch but is a double cylinder, keyed on both faces rather than a thumbturn inside.
8) The opening needs a fire rated deadbolt - can I use the Omnia RECTDB or do I need something else?
The Omnia RECTDB is a residential auxiliary deadbolt. Where the opening calls for a fire rating, the Hager 3215 single cylinder with 1 inch throw carries a fire rating and runs Cylinder x Thumbturn on 1-3/8 inch to 1-3/4 inch doors, as do the Hager 3115 Grade 2 and the Hager 3118 Grade 1 classroom deadbolt, both with a Schlage C keyway. The Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch.
9) I want keyed access from both sides instead of a thumbturn - what is the double cylinder version to order in place of the Omnia RECTDB?
The Omnia RECTDB is Cylinder x Thumbturn, keyed outside with a turnpiece inside. For key-both-sides, the Baldwin Reserve Contemporary Square Deadbolt is a double cylinder with square trim and the Baldwin Reserve Contemporary Round is the round-trim double cylinder. The Dexter DB1000 double cylinder is Grade 1 for 1-3/8 inch to 1-7/8 inch doors, the Dexter DB2000 double cylinder is Grade 2 for 1-3/8 inch to 1-3/4 inch, and the Design Hardware D1 Series double cylinder is Grade 1 extra heavy duty for 1-3/4 inch doors. Note that key-both-sides deadbolts are restricted on egress doors in many jurisdictions.
10) I am standardizing a building on interchangeable cores - what deadbolt works instead of the Omnia RECTDB?
The Omnia RECTDB ships as a keyed cylinder deadbolt kit. For a small format interchangeable core program, the Arrow E61 is a Grade 2 single cylinder deadlock with SFIC prep supplied less core, for 1-3/8 inch to 1-3/4 inch doors, and the Deltana CL200LAIC is a Grade 2 single deadbolt with interchangeable core, non-cylinder, on a 2-3/4 inch backset. The Delaney LM Series is a Grade 1 single cylinder less-core deadbolt in dull chrome US26D.
11) What looks like a substitute for the Omnia RECTDB but is not a drop-in?
A few parts share the deadbolt name without doing the same job. The Arrow 460 is a mortise lock strike, the door-frame side of the opening, not a lock. The Baldwin Reserve 8BR0618001 is a deadbolt spacer and the BEST 8T is a tubular deadbolt tube component, both sub-parts rather than complete kits. The Arrow E60 is a non-keyed exit deadlock with a blank plate outside and thumbturn inside, so it gives no key access from the exterior. The Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch, which need a mortise pocket rather than the bored prep the Omnia RECTDB uses.
12) The tenant has trouble gripping a thumbturn - is there an accessible alternative to the Omnia RECTDB?
The Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn, for 1-3/8 inch to 1-3/4 inch doors, and keeps the same Cylinder x Thumbturn function as the Omnia RECTDB, so the key side of the opening does not change. For a keypad alternative that removes the key entirely on the outside, the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote and the Codelocks CL200 is a surface deadbolt with key override.
13) The Omnia RECTDB is residential - what is the commercial deadlock to use on a 1-3/4 inch institutional door?
The Omnia RECTDB is a residential auxiliary deadbolt. On the commercial side, the Corbin Russwin DL3211 is a Grade 1 cylindrical deadlock, cylinder by blank, for 1-3/4 inch doors, and the DL3011 covers 1-3/4 inch to 2-1/4 inch. The Corbin Russwin DL2211 is a Grade 1 cylindrical deadlock in classroom function for 1-3/4 inch doors. Note that these are cylinder by blank, so there is no inside thumbturn the way the RECTDB has.
14) Is the Omnia RECTDB meant to be the only lock on the door, or does it go with a knob or lever?
It is an auxiliary deadbolt, meaning it mounts above the primary lockset and adds keyed security rather than replacing the latching hardware. The door still needs a knob or lever with a latch to stay closed. Plan on a second bore and a separate strike prep in the jamb for the bolt.
15) How far does the Omnia RECTDB stick out from the door face, and will the thumbturn clear a storm door or trim?
The keyed cylinder side projects 5/8 inch off the exterior face, and the interior turnpiece projects 1-3/8 inch. The exterior number is the one that matters if you have a storm or screen door hung close to the slab, and 5/8 inch is a low profile for a brass deadbolt. Inside, the 1-3/8 inch turn gives a decent grip for a gloved hand.
16) What size is the Omnia RECTDB rose, and will it cover the old escutcheon marks?
Both the exterior plate and interior plate are a 2-5/8 inch square. That is a rectangular, squared-off trim rather than a round rose, so it will not hide the outline of a previous round escutcheon on a painted or stained door. If you are swapping into an existing round trim footprint and want the marks covered, a round deadbolt such as the Bravura 310B Elite or the Brinks Raleigh is the closer visual match.
17) What finishes does the Omnia RECTDB deadbolt come in for matching the rest of my door hardware?
Eight finishes across both backsets: polished brass (US3), satin brass (US4), oil rubbed black (US10B), polished nickel (US14), satin nickel (US15), polished chrome (US26), satin chrome (US26D), and Tuscan bronze (TB). Because the body is solid brass rather than plated pot metal, the brass and bronze finishes wear in rather than flaking, which is what you want on an exterior door in a building where all the openings need to keep looking alike.
18) I manage a building and need the deadbolts to run on one key. Does the Omnia RECTDB work for that?
The RECTDB takes a standard keyed cylinder on the outside, so a locksmith can key it into a system the same way as any other bored deadbolt. If instead you want cores you can swap yourself when a tenant turns over, this is not the design for it, and an interchangeable core deadbolt like the Deltana CL200LAIC or the Arrow SFIC prep model supplied less core is the better route.
19) How many holes do I have to drill for the Omnia RECTDB, and can it drop into an existing deadbolt prep?
It is a bored deadbolt, so it goes into a standard cross bore through the face with an edge bore for the bolt, plus a strike mortise in the jamb. If a deadbolt is already in the door, confirm the existing backset is 2-3/8 or 2-3/4 inch and the slab is 1-3/4 inch thick, then order to match and the bolt will land in the same hole. The 2-5/8 inch square trim is what determines whether the old marks stay hidden.
20) My door prep is 2-3/4 inch backset but I am not sure - is there a deadbolt that fits either backset without ordering a specific one?
The Omnia RECTDB is ordered by backset, in 2-3/8 inch and 2-3/4 inch. If you would rather carry one part that covers both, the Brinks Raleigh Series round deadbolt and the Brinks Mendocino Series square deadbolt both have a 4-way adjustable backset and Cylinder x Thumbturn function, and the Cal-Royal ED500 and Falcon D111 also use an adjustable backset. That is the difference to weigh: a fixed-backset order versus a field-adjustable one.
21) Can I get the Omnia RECTDB square look in solid brass from another maker for a traditional entry?
The Omnia RECTDB is solid brass with a 2-5/8 inch square rectangular trim. In cast metal alternatives, the Emtek #11 Tuscany is a lost wax cast bronze deadbolt with Cylinder x Thumbturn function, and the Emtek 8323 Modern Disc is a brass deadbolt in double cylinder. The Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt in the Estate Series. Of those, only the Emtek Tuscany matches the RECTDB Cylinder x Thumbturn operation.
22) I do not want to bore the door all the way through - what surface or one-sided deadbolt can I use instead of the Omnia RECTDB?
The Omnia RECTDB is a bored deadbolt with trim on both faces. If the door cannot take a through-bore or you only want hardware on one side, the Callan Model 205S is a Grade 3 one-sided half-bore deadbolt, and the Codelocks CL200 is a surface deadbolt with key override. The Codelocks CL2200 is an electronic surface deadbolt in brushed steel, medium duty.
23) Is there a Cylinder x Thumbturn deadbolt with a cylinder guard for a door that has been attacked before?
The Cal-Royal CB160 is a Grade 2 single cylinder deadbolt with a tamper-resistant cylinder guard, running the same Cylinder x Thumbturn function as the Omnia RECTDB. For a heavier build on the same function, the Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt, and the Detex DX Series adds hinge side locking dead bolts with multi-point security on the pull side of the opening.
24) I am adding an auxiliary deadbolt above an existing knob - is there a version with no exterior trim plate?
The Omnia RECTDB carries a 2-5/8 inch square rectangular escutcheon on the door face. If you want the deadbolt without added trim, the Dormakaba M1960 is an M1000 Series single cylinder deadbolt, cylinder by turn, supplied with no trim. The Dormakaba D900 is a small case mortise deadbolt, cylinder by thumbturn, keyed different with SC keyways, for openings prepped for a mortise case rather than a bore.
25) I am putting the Omnia RECTDB across a multi-family property - is there a credential-based deadbolt for the same doors?
For unit doors where you would rather issue credentials than keys, the Dormakaba Nova-D is an RFID multihousing smart electronic deadbolt and the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override. The Codelocks CL2210 is an electronic mortise deadbolt. The Omnia RECTDB stays the mechanical option for the same openings, keyed outside with a thumbturn inside.
26) The opening needs a deadbolt and latch that work together off one lever - what replaces a separate Omnia RECTDB?
The Falcon H2101 is an entrance interconnected lock with a single cylinder deadbolt, Grade 2, combining the latch and deadbolt in one prep instead of a separate auxiliary deadbolt above the lockset. Where the door already has its primary lockset and you only need the added keyed bolt, the Omnia RECTDB is the standalone auxiliary deadbolt for that.
27) Does the classroom function on a Falcon D111 or D211 do the same thing as the Omnia RECTDB?
Both the Falcon D111, Grade 1 heavy duty, and the Falcon D211, Grade 2 medium duty, are listed as Cylinder x Thumbturn like the Omnia RECTDB, but they are classroom deadbolt locks in the D100 and D200 Series and are specified for classroom keying practice. The Omnia RECTDB is a residential auxiliary deadbolt kit in solid brass. If the door schedule calls out classroom function, the Falcon parts are the ones to price.
28) Is a solid brass deadbolt like the Omnia RECTDB worth it on an exterior door?
Brass does not rust, which is why it holds up on a weather-exposed entry where a plated steel body will bleed and pit at the edges. The RECTDB body is solid brass rather than a brass-plated shell, so the finish is carried by the material and the exposed square trim keeps its color rather than wearing through at the thumbturn.
