Omnia ARCHDBA34.34.10B – Frequently Asked Questions

1) Will the Omnia ARCHDB deadbolt fit a 1-3/8 inch door, or is it only for 1-3/4 inch doors?
Both. The ARCHDB Arch deadbolt is ordered by door thickness, and you pick either 1-3/8 inch or 1-3/4 inch when you order. Each thickness is offered with either backset and in every finish, so a 1-3/8 inch older interior door and a 1-3/4 inch entry door can both carry the same trim.
2) What backset does the Omnia Arch deadbolt use, and does it match the hole already drilled in my door?
The Arch deadbolt comes in a 2-3/8 inch backset and a 2-3/4 inch backset, which are the two standard bored backsets on residential doors. Measure from the door edge to the center of the existing cross bore and order to match; you are not adjusting this one in the field, so the backset is a specify-at-order decision.
3) Is the Omnia ARCHDB keyed on both sides or does it have a thumbturn inside?
Single cylinder: keyed cylinder outside, thumbturn inside. That means nobody needs a key to get out, which is what you want on a normal entry door. If you have glass within reach of the bolt and your local code allows a double cylinder, you would need a different product, such as the Baldwin Reserve Double Cylinder Contemporary Square Deadbolt or the Emtek 8323 Modern Disc double cylinder.
4) Is the Omnia ARCHDB rated for a commercial building or apartment corridor doors?
It is a residential deadbolt. Omnia lists the ARCHDB for single-family homes, condos, townhouses and multi-family units. For a commercial opening where a specifier is calling out a grade, go to something like the Cal-Royal CRB800 Grade 1 heavy duty single cylinder deadbolt or the Dexter DB1000 Series Grade 1, both cylinder by thumbturn.
5) What is the closest equivalent to the Omnia ARCHDB single cylinder deadbolt from another brand?
The Omnia ARCHDB is a cylinder x thumbturn deadbolt in solid brass for residential entry doors. For the same keyed-outside, turn-inside function from another maker, the Deltana CL200LM is a Grade 1 single cylinder deadbolt with cylinder x thumbturn function, and the Dexter DB1000-SCT is a Grade 1 cylinder x thumbturn deadbolt covering doors from 1-3/8 to 1-7/8 inch. The Bravura 910005 is a Grade 2 rectangle single cylinder deadbolt, which is the closest in trim shape to the ARCHDB rectangular kit.
6) I need a deadbolt for a commercial opening with an ANSI grade on the submittal - what should I use instead of the Omnia ARCHDB?
The Omnia ARCHDB is built for residential entry use. When a project requires a stated ANSI/BHMA grade, the Accentra D111 is a Grade 1 cylinder x thumbturn deadbolt with a 2-3/8 inch backset covering 1-3/8 to 1-3/4 inch doors, the Falcon D111 is a Grade 1 heavy duty cylinder x thumbturn deadbolt with adjustable backset, and the Cal-Royal CRB800 is a heavy duty cylinder x thumbturn deadbolt with a UL 3-hour fire rated latch. For a graded medium-duty option, the Falcon D211 is Grade 2 cylinder x thumbturn.
7) The opening has glass next to the door and the thumbturn is a concern - what deadbolt replaces the Omnia ARCHDB there?
The Omnia ARCHDB is keyed outside with an interior thumbturn, so a hand reaching through adjacent glass can retract it. Where that is a concern, a double cylinder deadbolt requires a key on both sides: the Dexter DB1000-DCT is Grade 1 for 1-3/8 to 1-7/8 inch doors, the Dexter DB2000-DCT is Grade 2 for 1-3/8 to 1-3/4 inch doors, and the Design Hardware D1 Series is a Grade 1 extra heavy duty double cylinder for 1-3/4 inch doors. Confirm local egress code before specifying a double cylinder on a required exit.
8) My door is thicker than 1-3/4 inch - what deadbolt works where the Omnia ARCHDB does not?
The Omnia ARCHDB is offered for 1-3/8 inch and 1-3/4 inch door thicknesses. For thicker stock, the Corbin Russwin DL3011 cylindrical deadlock covers 1-3/4 to 2-1/4 inch doors, and the Deltana 7312KA2 double cylinder deadbolt covers 1-3/8 to 2 inch doors. The Dexter DB1000 single cylinder goes to 1-7/8 inch if you only need a small amount of extra range.
9) Which deadbolts look like substitutes for the Omnia ARCHDB but will not drop into the same bored prep?
The Omnia ARCHDB is a bored deadbolt with a 2-3/8 or 2-3/4 inch backset in a standard cross-bore door prep. Several nearby items are not interchangeable with it: the Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch and need a mortise pocket, the Codelocks CL200 is a surface-mounted deadbolt with key override, the DynaLock 1300 Series is a mortise electric deadbolt, and the Arrow 460 is a mortise lock strike rather than a lock. The BEST 8T is the tubular deadbolt tube component of a T Series lock, not a complete deadbolt.
10) Can I use the Omnia ARCHDB on a fire rated door, or do I need a different deadbolt?
The Omnia ARCHDB is specified as a residential deadbolt. Where a fire rated opening is involved, the Hager 3115 Grade 2 cylinder x thumbturn deadbolt, the Hager 3215 single cylinder with 1 inch throw, and the Hager 3118 Grade 1 classroom deadbolt are all fire rated and cover 1-3/8 to 1-3/4 inch doors with a Schlage C keyway. The Cal-Royal CRB800 is a heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch.
11) What finishes does the Omnia Arch deadbolt come in for matching the rest of the door hardware?
Seven finishes across both backsets and both door thicknesses: polished brass (US3), satin brass (US4), black oil-rubbed (US10B), polished nickel plated (US14), satin nickel (US15), polished chrome (US26) and Tuscan bronze (TB). Because the body is solid brass rather than plated steel, the living finishes hold up outdoors better than a coated base metal.
12) I want to add a deadbolt above an existing knob, not replace the lockset. Is this the right part?
Yes. The ARCHDB is an auxiliary deadbolt, meaning it installs on its own bore above or below an existing knob or lever set rather than interconnecting with it. If you would rather have one unit where the lever retracts the bolt together, that is an interconnected lock instead, like the Falcon H2101 entrance interconnected lock with single cylinder deadbolt.
13) I have a mix of door thicknesses across a building. Can I standardize on the Omnia Arch deadbolt?
Yes, and that is a common use for it. The same Arch trim is built for 1-3/8 inch and 1-3/4 inch doors and in both the 2-3/8 inch and 2-3/4 inch backsets, so every opening reads identically from the hallway while each unit is ordered to the door it goes on. Keep the finish constant and vary only backset and thickness on the order.
14) We key our buildings on small format interchangeable core - is the Omnia ARCHDB the right choice or is there an SFIC alternative?
The Omnia ARCHDB is a keyed single cylinder deadbolt for residential entries and is supplied with its own cylinder. If you standardize on interchangeable core, the Deltana CL200LAIC is a Grade 2 single cylinder deadbolt prepped for an interchangeable core and supplied less cylinder, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock with SFIC prep less core for 1-3/8 to 1-3/4 inch doors, and the Delaney LM Series is a Grade 1 single cylinder less core deadbolt in dull chrome US26D.
15) I want the same arch or decorative look as the Omnia ARCHDB from another brand - what are the options?
The Omnia ARCHDB pairs solid brass construction with an arch trim and finishes including polished brass, satin brass, black oil-rubbed, polished and satin nickel, polished chrome, and Tuscan bronze. For a comparable decorative approach, the Emtek #11 Tuscany is a lost wax cast bronze cylinder x thumbturn deadbolt, and the Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt. Bravura offers shaped trim in the 310B Elite traditional round, 310RC Elite contemporary round, and 310SC Elite contemporary square, all Grade 2 cylinder x thumbturn.
16) We are moving a property to keypad entry - what takes the place of the Omnia ARCHDB deadbolt?
The Omnia ARCHDB is a mechanical keyed deadbolt with an interior thumbturn. For credential-based entry in the same deadbolt position, the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, the Codelocks CL2200 is an electronic surface deadbolt in brushed steel, the Codelocks CL2210 is an electronic mortise deadbolt, and the Dormakaba Saffire LX-D and Nova-D are RFID electronic deadbolts for multihousing use.
17) What should I use instead of the Omnia ARCHDB on a door that needs no key on the inside face at all?
The Omnia ARCHDB puts a keyed cylinder outside and a thumbturn inside. If the opening calls for a different arrangement, the Arrow E60 is a Grade 2 non-keyed exit deadlock with a blank plate outside and thumbturn inside for 1-3/8 to 1-3/4 inch doors, and the Corbin Russwin DL3211 is a Grade 1 cylindrical deadlock with cylinder outside and blank inside for 1-3/4 inch doors. For a single-face application, the Callan 205S is a Grade 3 one-sided half-bore deadbolt.
18) The Omnia ARCHDB has a standard thumbturn - is there a deadbolt with an easier turn for accessibility?
The Omnia ARCHDB uses a 1-3/8 inch projection interior turnpiece operated by hand without a key. Where grip strength is a consideration, the Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn for 1-3/8 to 1-3/4 inch doors, which is the same cylinder x thumbturn function with a larger lever-style turn.
19) Is there a deadbolt with added cylinder protection compared to the Omnia ARCHDB?
The Omnia ARCHDB is a solid brass auxiliary deadbolt with a keyed exterior cylinder. If the exposure calls for hardware that resists attack at the cylinder, the Cal-Royal CB160 is a Grade 2 single cylinder deadbolt with a tamper-resistant cylinder guard, and the Detex DX Series is a hinge side locking deadbolt with multi-point security.
20) Is the Omnia ARCHDB a round deadbolt or a square one?
Arch describes a rectangular escutcheon, 2-3/4 by 2-5/8 inches, not a round rose. If the openings around it are trimmed round, a round-trim deadbolt such as the Bravura 310B Elite or the Callan Model 200S-G2 round trim will line up better visually; for a squared contemporary look there is the Bravura 310SC Elite square deadbolt.
