Dormakaba QDB182-626-S4-DBS-SC – Frequently Asked Questions

1) Is the Dormakaba QDB182 deadbolt fire rated for a labeled door?
It is UL/cUL listed for 3 hour "A" label single door applications up to 4 feet by 8 feet, positive pressure rated to UL10C/UBC 7-2 (1997), and UL10B pressure rated. It also carries the California State Reference Code listing (formerly Title 19, Fire Marshal). That covers most labeled openings in a commercial corridor or stairwell.
2) What door prep does the Dormakaba QDB182 deadbolt need, and will it drop into an existing bore?
Standard door prep: a 2-1/8 inch (54mm) diameter cross bore with a 2-3/4 inch (70mm) square backset as standard, or 2-3/8 inch (60mm) if you order that backset. Those are the two normal backsets on a bored deadbolt, so an existing 161 style prep takes it without redrilling. The latch faceplate is 1-1/8 inch x 2-1/4 inch and you can order round or square faceplate corners to match the mortise already cut in your door edge.
3) Will the Dormakaba QDB182 latch into the strike already in my frame?
The bolt throws a full 1 inch (25.4mm) and the deadbolt ships with a 1-1/8 inch x 2-3/4 inch square corner strike, which is the standard commercial deadbolt strike. If your frame is already prepped for that strike size, the QDB182 lands in it. If your existing strike has radius corners or a different lip, other strike options are available. A 1 inch throw needs a full depth strike pocket in the frame, not a shallow residential one.
4) What is the difference between a double cylinder deadbolt like the QDB182 and a single cylinder with a thumbturn?
The QDB182 is keyed on both sides, no thumbturn. Use it where the door has glass or a sidelite next to it and you do not want someone reaching through and turning a knob to get out. The trade off is egress: anyone inside needs a key to unlock it, so it is restricted or prohibited on required exit doors in many occupancies, and your local code official decides that. If you want key outside and turn inside, the single cylinder version of the same series is the one to order, or a peer like the Dexter DB1000 single cylinder, which is also Grade 1.
5) Can I use my existing small format interchangeable cores in a Dormakaba QDB100 deadbolt?
Yes. Order the SFIC version, which comes prepped and without a core, and drop in the 6 or 7 pin SFIC cores you already run in the building. That keeps the deadbolt on your existing master key system without rekeying. If you are not on an SFIC system, the conventional cylinder version uses a 6 pin brass cylinder in the Schlage "C" keyway. There is also a less cylinder option if your locksmith is supplying cylinders.
6) Can I key several Dormakaba QDB182 deadbolts alike across a building?
Yes. Keyed alike is a selectable option at order, keyed different is the standard, and you can also specify none if you are supplying your own cylinders. Beyond that the series supports master keying, grand master keying and construction keying, so a property with a lot of storage rooms or utility doors can sit under one master. Two keys come with each lockset.
7) What is the closest Grade 1 double cylinder deadbolt to the Dormakaba QDB182?
The Design Hardware D1 Series double cylinder deadbolt is the closest match on paper: it is a Grade 1 double cylinder deadbolt rated extra heavy duty, and it is built for 1-3/4 inch doors. The QDB182 is also a Grade 1 heavy duty double cylinder deadbolt, and it carries a wider door range of 1-3/8 inch to 2 inch, with 8Q00082 spacer rings required at 1-3/8 inch. The Dexter DB1000 double cylinder is another Grade 1 double cylinder option, covering 1-3/8 inch to 1-7/8 inch doors. If the opening is a standard 1-3/4 inch commercial door, all three will prep the same; if the door is thicker than 1-7/8 inch, the QDB182 is the one that covers it.
8) Is there a Grade 2 double cylinder deadbolt for a lighter duty opening than the QDB182 suits?
Yes. The Dexter DB2000 is a Grade 2 double cylinder deadbolt covering 1-3/8 inch to 1-3/4 inch doors, the Hager 3214 is a Grade 2 double cylinder deadbolt with a Schlage C keyway and a fire rating over the same 1-3/8 inch to 1-3/4 inch range, and the Delaney LU Series 320601 is a Grade 2 double cylinder in stainless steel US32D. The QDB182 sits a grade above these at ANSI/BHMA A156.5 Grade 1 with a solid forged housing, a full 1 inch throw bolt with a hardened steel roller pin, and anti-drill ball bearings on non-IC cylinders. For an interior storage room or a low-traffic tenant door, the Grade 2 units cover the function; for an exterior or high-traffic opening written to Grade 1, the QDB182 is the one that meets the spec.
9) What should I use instead of the QDB182 if the egress side needs a thumbturn rather than a key?
A double cylinder deadbolt like the QDB182 is keyed on both sides, which many life safety codes do not allow on a required egress door. For a keyed outside and thumbturn inside, the Dormakaba QDB100 series covers that function as well, and among other Grade 1 options the Delaney LM Series 301702 is a Grade 1 cylinder x thumbturn less core deadbolt in dull chrome US26D, the Falcon D111 is a Grade 1 heavy duty cylinder x thumbturn deadbolt with an adjustable backset, and the Deltana CL200LM is a Grade 1 single cylinder deadbolt. The Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and a 6-pin cylinder over a 1-3/8 inch to 1-3/4 inch door range. The QDB100 series thumbturn is ADA compliant per ANSI A117.1.
10) Which double cylinder deadbolts take a small format interchangeable core, and how does the QDB182 handle SFIC?
The QDB182 is offered in an SFIC cylinder configuration with no core included, so existing 6-pin or 7-pin small format cores drop straight in, alongside conventional Schlage C keyway and less cylinder options. Among comparables set up for interchangeable cores, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock with SFIC prep less core for 1-3/8 inch to 1-3/4 inch doors, and the Deltana CL200LAIC is a Grade 2 single cylinder interchangeable core deadbolt with a 2-3/4 inch backset. Both of those are single cylinder, so on a both-sides-keyed opening with an existing SFIC system the QDB182 SFIC configuration is the one that matches.
11) How well does the Dormakaba QDB100 deadbolt resist drilling and sawing?
The bolt carries a hardened steel roller pin so a hacksaw blade spins on it rather than cutting through, and the housing is solid forged with an anti-drill design using two ball bearings on the non-IC cylinder versions. That drill protection is tied to the conventional cylinder build, so if you spec SFIC you are relying on the core's own protection plus the forged housing.
12) What finishes does the Dormakaba QDB100 deadbolt come in, and will it match the rest of my building's hardware?
Five finishes: 605 bright brass, 613 oil rubbed bronze, 619 satin nickel, 625 bright chrome and 626 satin chrome. Those are BHMA numbers, so if your existing levers and closers are specified 626, the deadbolt in 626 matches them. The exposed trim is solid forged brass plated to the finish designation, not a plated pot metal casting, so it holds up better in exterior and high traffic locations.
13) Is a Grade 1 auxiliary deadbolt like the QDB182 overkill for a storage room or a park restroom?
No, that is exactly where the QDB100 series lands. Rest stop and state park restrooms, storage rooms and commercial office doors are the stated applications, and it is normally installed above a cylindrical lockset as a second point of security rather than as the only lock on the door. If the door sees light residential duty and no abuse, a Grade 2 like the Arrow DBX61 or a Grade 3 like the Cal-Royal ED500 covers it for less hardware.
14) Is there a hurricane rated version of the Dormakaba QDB100 deadbolt?
Hurricane compliance is an available option on the series, carrying a Miami Dade N.O.A. If you are building in a high velocity hurricane zone in South Florida, specify that option at order rather than assuming a standard QDB182 carries it.
15) What keyway options are available on the Dormakaba QDB100 deadbolt if I already run Schlage or Sargent keys?
Keyways cover BF-SFIC "F", KW Kwikset, WE Weiser, SC Schlage, GA Yale and LA Sargent, plus LC less cylinder. So a building already keyed in Schlage or Sargent can add these deadbolts onto the existing system rather than carrying a second key. The stock conventional cylinder configuration is the Schlage "C" keyway.
16) Can a Corbin Russwin DL3011 deadlock replace a Dormakaba QDB182?
Not directly, on two counts. The DL3011 is a Grade 1 cylindrical deadlock in a cylinder x blank configuration, so the inside face is a blank plate with no key and no turn, where the QDB182 is keyed on both sides. The DL3011 also carries a door thickness range of 1-3/4 inch to 2-1/4 inch, while the QDB182 covers 1-3/8 inch to 2 inch. The DL3211 and DL2211 are the same cylinder x blank arrangement on 1-3/4 inch doors. Those are the right call when you want the door secured from outside only; for both-sides keyed operation the QDB182 is the function to match.
17) What is a Grade 3 double cylinder deadbolt alternative for a light residential rental door?
The Callan Model 210S is a Grade 3 double cylinder deadbolt, and the Deltana 7312KA2 is a Grade 3 double cylinder deadbolt keyed alike in pairs with a 1-3/8 inch to 2 inch door thickness range. Both give both-sides-keyed operation at a lighter grade. The QDB182 is a Grade 1 heavy duty commercial deadbolt with a solid forged housing and saw-resistant hardened steel roller pin, and it is UL/cUL listed for 3 hour A label single door applications. On a fire rated opening or anywhere the spec calls Grade 1, the Grade 3 units will not carry the listing.
18) I need a decorative double cylinder deadbolt to match residential trim - is the QDB182 the wrong choice?
For a decorative opening it likely is. The QDB182 exposed trim is solid forged brass plated to the finish designation, offered in 605 bright brass, 613 oil rubbed bronze, 619 satin nickel, 625 bright chrome and 626 satin chrome, in round or square faceplate corners - a commercial appearance. If the door calls for designer trim, the Baldwin Reserve double cylinder deadbolt comes in contemporary round and contemporary square, the Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt, and the Emtek 8323 Modern Disc is a brass double cylinder deadbolt. Those are styled for architectural and residential entries; the QDB182 is the Grade 1 commercial answer.
19) The QDB182 comes in 2-3/8 inch and 2-3/4 inch backsets - what if the field backset is uncertain?
The QDB182 is ordered to a fixed backset, either 2-3/4 inch square standard or 2-3/8 inch, so the crossbore centerline has to be known before the order goes in. When you are prepping unknown doors or buying stock for a mixed property, an adjustable backset unit removes the guess: the Falcon D111 is a Grade 1 heavy duty deadbolt with an adjustable backset, the Cal-Royal ED500 is a Grade 3 deadbolt with an adjustable backset for 1-3/8 inch to 1-3/4 inch doors, and the Brinks Raleigh E2401 has a 4 way adjustable backset. Those are single cylinder cylinder x thumbturn units, so for a both-sides-keyed opening you still measure and order the QDB182 to the correct backset.
20) Is a surface mounted or electronic deadbolt an option in place of the QDB182?
They solve a different problem. The QDB182 is a bored deadbolt that goes into a standard 2-1/8 inch diameter crossbore with a 1-1/8 inch by 2-1/4 inch faceplate. If the door cannot be bored or you want code entry, the Codelocks CL200 is a light duty surface deadbolt with key override, the CL2200 is a light duty electronic surface deadbolt in brushed steel, and the CL2210 is an electronic mortise deadbolt. The Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, and the DynaLock 1300 Series is a heavy duty mortise electric deadbolt for access control tie-in. None of those are Grade 1 bored deadbolts; where the spec calls for a Grade 1 mechanical bolt on a standard door prep, the QDB182 is the match.
21) Does the QDB182 use the same strike as the deadbolts I already have, and what if I need a different one?
The QDB182 ships with a standard deadbolt strike, 1-1/8 inch by 2-3/4 inch with square corners, which is the common commercial deadbolt strike prep. If the frame is prepped for a mortise lock body rather than a bored deadbolt, the Arrow 460 is a mortise lock strike with straight lip covering latchbolt and deadbolt functions for 1-3/4 inch doors, and it is a strike only, not a lock. Match the existing frame cutout before ordering: a bored deadbolt strike and a mortise strike are not interchangeable in the same frame prep.
22) For an exit only door that needs no key outside, is there an alternative to a double cylinder deadbolt?
Yes. The Arrow E60 is a Grade 2 exit deadlock, non-keyed, in a blank plate x thumbturn arrangement for 1-3/8 inch to 1-3/4 inch doors, and the Callan Model 205S is a Grade 3 one sided half-bore deadbolt. Both throw the bolt from inside with no outside key access, which suits a service or exit only opening. The QDB182 is keyed on both sides for openings where the door must also be operated from outside, and it is available for 1-3/8 inch through 2 inch doors, with spacer rings 8Q00082 needed at 1-3/8 inch.
