Omnia MODDBA34.34.26D – Frequently Asked Questions

1) Will the Omnia MODDB auxiliary deadbolt fit a 1-3/8 inch door, or is it 1-3/4 only?
Both. The MODDB kit is built for 1-3/8 inch and 1-3/4 inch doors, and you pick the thickness when you order. Backset is a separate choice, 2-3/8 inch or 2-3/4 inch, and every one of the seven finishes is offered in both backsets at both thicknesses. Measure the door edge and the distance from the door edge to the center of the existing bore before you order, because the kit is built to the thickness you select rather than adjusting on site.
2) Should I use an auxiliary deadbolt like the Omnia MODDB or a full entry lockset?
An auxiliary deadbolt is a second lock, not the handle. The MODDB adds a keyed bolt above or below whatever knob, lever, or handleset already latches the door, which is how most residential entries are secured. It does not latch the door on its own and it has no handle, so if you are hanging hardware on a bare door you still need a lockset or passage set with it. If you want the deadbolt and the latch tied together in one mechanism, an interconnected lock like the Falcon H2101 does that job instead.
3) Is the Omnia MODDB deadbolt suitable for a commercial building or apartment corridor door?
It is a residential deadbolt. Omnia lists the MODDB as residential, and the finishes and solid brass trim are aimed at entry doors in houses, condos, townhomes, and multi-family units rather than commercial openings. For a commercial door or anything on a rated corridor, look at a graded commercial deadbolt instead: the Corbin Russwin DL3011 or DL3211 are Grade 1 cylindrical deadlocks for 1-3/4 inch doors, and the Cal-Royal CRB800 is a heavy duty single cylinder unit with a UL 3-hour fire rated latch.
4) What looks like a substitute for the Omnia MODDB single cylinder deadbolt but is not?
Several deadbolts in the same size class do not do what the MODDB does. The Arrow E60 is a Grade 2 exit deadlock with a blank plate outside and a thumbturn inside, so it cannot be keyed from the exterior. The Corbin Russwin DL3211 and DL2211 are Grade 1 cylindrical deadlocks with cylinder x blank trim, keyed outside with no inside turn. The Callan 205S is a Grade 3 one-sided half-bore deadbolt, which mounts on one face and does not go through the door as a cylinder x thumbturn assembly. The Baldwin 8BR0618001 is a deadbolt spacer, a fitting part rather than a working lock, and the BEST 8T is a tubular deadbolt tube component rather than a complete deadbolt.
5) What is a direct alternative to the Omnia MODDB auxiliary deadbolt if the door needs an ANSI Grade 1 single cylinder deadbolt?
The Omnia MODDB is a single cylinder auxiliary deadbolt with a keyed cylinder outside and a thumbturn inside, built in solid brass for residential openings. When the specification calls for a graded product, the Accentra D111 is a Grade 1 single cylinder deadbolt with cylinder x thumbturn function and a door thickness range of 1-3/8 inch to 1-3/4 inch, which covers the same 1-3/8 inch and 1-3/4 inch doors the MODDB is built for. The Dexter DB1000-SCT is another Grade 1 cylinder x thumbturn deadbolt, with a 1-3/8 inch to 1-7/8 inch door thickness range for doors thicker than 1-3/4 inch.
6) Which deadbolt should be used instead of the Omnia MODDB on a fire rated opening?
The Omnia MODDB is a residential auxiliary deadbolt. For an opening where a fire rating is required, the Hager 3115 is a cylinder x thumbturn deadbolt with a fire rating and a Schlage C keyway, fitting doors 1-3/8 inch to 1-3/4 inch. The Hager 3215 is a single cylinder deadbolt with a 1 inch throw, Grade 2, also fire rated across the same 1-3/8 inch to 1-3/4 inch thickness range. The Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch.
7) What is the equivalent of the Omnia MODDB deadbolt for a door that must be keyed on both sides?
The Omnia MODDB is a single cylinder deadbolt, keyed outside and thumbturn inside. Where a glass front or sidelite opening calls for key operation on both sides, the Delaney LU Series 320601 is a Grade 2 double cylinder deadbolt in stainless steel US32D, and the Dexter DB1000-DCT is a Grade 1 double cylinder deadbolt fitting doors 1-3/8 inch to 1-7/8 inch. For a contemporary trim shape close to the Modern collection styling, the Baldwin Reserve DC.CRD is a double cylinder contemporary round deadbolt and the Baldwin Reserve DC.CSD is the contemporary square version. Double cylinder deadbolts are restricted on egress doors in many jurisdictions, so confirm the local code before specifying one.
8) What deadbolt takes an interchangeable core instead of the fixed cylinder in the Omnia MODDB?
The Omnia MODDB comes as a keyed cylinder outside with a thumbturn inside. On a property standardized on small format interchangeable cores, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock prepped for SFIC and supplied less core, for doors 1-3/8 inch to 1-3/4 inch. The Deltana CL200LAIC is a Grade 2 single cylinder deadbolt with interchangeable core prep and a 2-3/4 inch backset, matching one of the two MODDB backsets. The Delaney LM Series 301702 is a Grade 1 single cylinder less core deadbolt in dull chrome US26D.
9) How far does the Omnia MODDB deadbolt stick out from the door face?
Five-eighths of an inch on the outside, and the interior turnpiece projects 1-3/8 inches. That outside projection matters if you have a storm door or screen door swinging past it, and the interior figure is what you check against a door stop, a cased opening, or anything mounted close to the inside face. Overall the escutcheon runs 2-3/4 inches by 2-5/8 inches with a 2-5/8 inch diameter trim.
10) What finishes does the Omnia MODDB deadbolt come in, and will it match my other Omnia Modern hardware?
Seven finishes: Black Oil-Rubbed, Polished Nickel Plated, Satin Nickel, Polished Chrome, Satin Chrome, Polished Brass, and Satin Brass. All seven are offered in both backsets and both door thicknesses, so a property manager standardizing across a building can hold one finish and still get whatever backset each door needs. The MODDB belongs to Omnia's Modern collection, which is the range to stay within if you want the levers and trim on the same door to match.
11) I need a deadbolt with an ANSI grade for a spec. Does the Omnia MODDB work?
If the drawing calls out a grade, specify a graded product instead of the Omnia MODDB. Options in the same cylinder and thumbturn function: the Accentra D111 and the Deltana CL200LM are Grade 1, the Arrow DBX61 and the Deltana CL200LA are Grade 2, and the Dexter DB1000 single cylinder is Grade 1 covering 1-3/8 inch through 1-7/8 inch doors. All of them lock and unlock the same way as the MODDB from the buyer's side.
12) My doors have different backsets. Is there a deadbolt with an adjustable backset instead of picking one?
The Omnia MODDB is ordered to a fixed backset, either 2-3/8 or 2-3/4 inches, so a mixed building means ordering both. If you would rather stock one part and set it on site, several adjustable-backset deadbolts cover both dimensions from a single box: the Brinks Raleigh and Mendocino Series have a four-way adjustable backset, and the Cal-Royal ED500 and Falcon D111 are also adjustable. The trade-off is styling, since none of those are the Omnia Modern trim.
13) Can I key the Omnia MODDB deadbolt to match the lock already on the door?
The MODDB takes a keyed cylinder outside, so a locksmith can key it to an existing system the same way as any other keyed residential deadbolt. What decides it is the keyway on your existing cylinder, so have that identified before ordering. If you specifically need a small format interchangeable core so a facility can rekey without pulling hardware, the Arrow E61 SFIC-prep deadlock ships less core for 1-3/8 to 1-3/4 inch doors and the Deltana CL200LAIC is an interchangeable core deadbolt on a 2-3/4 inch backset.
14) Is there a contemporary square trim deadbolt to match an Omnia MODDB opening where round trim does not suit the door?
The Omnia MODDB is a Modern collection deadbolt with a 2-5/8 inch diameter round rose. Where square trim is wanted instead, the Bravura 310SC Elite is a Grade 2 contemporary square deadbolt with cylinder x thumbturn function, and the Brinks Mendocino E2402 is a contemporary square single cylinder deadbolt with a 4-way adjustable backset. The Callan 200S is a Grade 3 single cylinder square trim deadbolt with the same cylinder x thumbturn operation. For a round contemporary alternative, the Bravura 310RC Elite is the round Grade 2 version.
15) What is the electronic version of a single cylinder deadbolt like the Omnia MODDB for a multi-family property?
The Omnia MODDB is a mechanical keyed deadbolt with an interior thumbturn. Where a property wants credential or code entry on the same style of opening, 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 Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, and the Codelocks CL2200 is a medium duty electronic surface deadbolt in brushed steel. Surface mounted units such as the CL2200 use a different door prep than a bored deadbolt.
16) What single cylinder deadbolt has an ADA friendly thumbturn as an alternative to the Omnia MODDB turnpiece?
The Omnia MODDB uses a 1-3/8 inch projecting interior turnpiece. Where an ergonomic turn is wanted, the Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn, covering doors 1-3/8 inch to 1-3/4 inch with cylinder x thumbturn function. The Cal-Royal CB160 is a Grade 2 single cylinder deadbolt with a tamper-resistant cylinder guard for the same function.
17) What solid brass or cast metal deadbolt is comparable to the Omnia MODDB for a high-end residential entry?
The Omnia MODDB is a solid brass single cylinder deadbolt in the Modern collection, offered in polished and satin brass, polished and satin nickel, polished and satin chrome, and black oil-rubbed. In the same decorative class, the Emtek #11 Tuscany is a lost wax cast bronze deadbolt with cylinder x thumbturn function, and the Emtek 8323 Modern Disc deadbolt is brass in a double cylinder configuration. For a European mortise approach on the same kind of entry, the Emtek 2050 and 2051 are mortise deadbolts with an integrated roller latch, square and round respectively, both cylinder x thumbturn.
18) If the opening needs a deadbolt combined with a latch rather than an auxiliary deadbolt like the Omnia MODDB, what should be used?
The Omnia MODDB is an auxiliary deadbolt, meant to add locking beyond a primary lockset. Where one device should handle both, the Falcon H2101 is a Grade 2 entrance interconnected lock with a single cylinder deadbolt, and the Baldwin Estates 8011 is a contemporary 1-5/8 inch deadbolt in entrance function. The Emtek 2050 and 2051 European mortise deadbolts include an integrated roller latch.
