Dormakaba QDB186-613-S4-DBS-SC – Frequently Asked Questions

1) Is the Dormakaba QDB186 deadbolt fire rated for a labeled door?
UL/cUL listed for 3 hours on "A" label single doors up to 4 feet by 8 feet, positive pressure rated to UL10C/UBC 7-2 (1997), and also UL10B pressure rated. It carries ANSI/BHMA A156.5 Grade 1 and meets ANSI A117.1 accessibility, with an ADA compliant thumbturn. There is a hurricane compliant option under Miami DADE N.O.A. and it meets the California State Reference Code formerly known as Title 19.
2) What door prep does the Dormakaba QDB186 deadbolt need, and will it drop into an existing deadbolt hole?
Standard prep: a 2-1/8 inch (54mm) diameter cross bore with a 2-3/4 inch (70mm) backset, which is the normal commercial deadbolt prep. A 2-3/8 inch (60mm) backset version is also built if the existing bore sits closer to the edge. The strike is the standard 1-1/8 inch x 2-3/4 inch square corner deadbolt strike, and the latch faceplate is 1-1/8 inch x 2-1/4 inch, available with square or round corners so it matches whatever mortise is already cut in the door edge. Retrofitting an old bolt is usually just a matter of matching backset and faceplate corner style.
3) Can I use my existing small format interchangeable cores with the Dormakaba QDB186?
Yes. The QDB100 deadbolt is ordered with an SFIC prep and no core included, so your existing 6- or 7-pin small format cores drop straight in and the bolt joins your current keying system. The other two choices are a conventional 6-pin brass cylinder in the Schlage "C" keyway, or less cylinder if a locksmith is supplying it. Conventional cylinders ship two keys per lockset and support master, grand master and construction keying.
4) What is the Grade 1 equivalent of the Dormakaba QDB186 from another brand?
Closest like for like is the Hager 3118, a Grade 1 classroom deadbolt with a Schlage C keyway and a 6-pin cylinder, listed for 1-3/8 inch to 1-3/4 inch doors and fire rated. The Falcon D111 is also a Grade 1 heavy duty classroom deadbolt with a cylinder by thumbturn function and an adjustable backset, which is handy when you are not sure what backset is bored in the door. Accentra D111 is another Grade 1 single cylinder deadbolt, fixed at a 2-3/8 inch backset. Note the QDB100 covers doors up to 2 inches thick, wider than the 1-3/4 inch top end on the Hager and Accentra.
5) I need a deadbolt keyed on both sides instead of a thumbturn. Is the QDB186 the right one?
No. The QDB186 is cylinder by thumbturn, so the inside is always a turn knob and there is no key on the room side. For a double cylinder bolt, look at the Design Hardware D1 Series, a Grade 1 extra heavy duty double cylinder deadbolt for 1-3/4 inch doors, or the Dexter DB1000 double cylinder, Grade 1 for 1-3/8 inch to 1-7/8 inch doors. Be aware that double cylinder bolts are restricted on egress doors in many jurisdictions, which is exactly why the thumbturn version carries the ADA and accessibility compliance.
6) Will the QDB186 latch into the strike that is already in my frame?
It ships with the standard 1-1/8 inch x 2-3/4 inch square corner deadbolt strike, which is the common commercial deadbolt strike, so an existing frame cut for that size takes it directly and Dormakaba builds other strike options for frames that are not. What matters more is depth: the bolt throws a full 1 inch, so the frame pocket behind the strike has to be deep enough to take it. On a hollow metal frame check the strike box, and on a wood jamb drill the pocket out fully rather than letting the bolt bottom out.
7) What is the closest Grade 1 classroom-function deadbolt to the Dormakaba QDB186?
The Falcon D111 is the nearest equivalent. It is a Grade 1 heavy duty classroom deadbolt in the D100 Series with a cylinder x thumbturn function, matching the QDB186's Grade 1 heavy duty rating and cylinder x thumbturn operation. The Hager 3118 is a second Grade 1 classroom deadbolt, keyed to the Schlage C keyway with a 6-pin cylinder and fitting doors 1-3/8 inch to 1-3/4 inch. The QDB186 covers a wider door range and is offered in 2-3/4 inch and 2-3/8 inch backsets.
8) What is the difference between the Dormakaba QDB186 and the Corbin Russwin DL3011 or DL3211 deadlocks?
The Corbin Russwin DL3011 and DL3211 are Grade 1 cylindrical deadlocks with a cylinder x blank trim, meaning there is no interior thumbturn to retract the bolt from inside. The DL3011 fits doors 1-3/4 inch to 2-1/4 inch and the DL3211 fits 1-3/4 inch doors. The Dormakaba QDB186 is a cylinder x thumbturn deadbolt, so the inside face can throw and retract the bolt without a key. If the drawing calls for cylinder x blank, the DL series is the match; if it calls for a thumbturn, it is not.
9) Which deadbolt takes an interchangeable core if the facility keys everything on small format cores?
The Dormakaba QDB186 is available in an SFIC cylinder configuration supplied without a core, so an existing small format core drops in. Among alternatives, the Deltana CL200LAIC is a Grade 2 single cylinder deadbolt built for an interchangeable core and supplied non-cylinder with a 2-3/4 inch backset, and the Arrow E61 is a Grade 2 single cylinder deadlock with SFIC prep less core for doors 1-3/8 inch to 1-3/4 inch. The QDB186 is the Grade 1 option of the three.
10) Which deadbolts look like a substitute for the Dormakaba QDB186 but are not?
Several deadbolts in the same size class change how the opening works. 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 corridor. The Callan Model 205S is a Grade 3 one-sided half-bore deadbolt, operating from one face only. The Arrow 460 is a mortise lock strike, not a lock. The Codelocks CL200 is a light duty surface deadbolt with key override, mounted on the door face rather than through a bored prep. The Dormakaba QDB186 is a Grade 1 heavy duty bored deadbolt with cylinder outside and thumbturn inside.
11) What Grade 1 single cylinder deadbolt alternatives are there to the Dormakaba QDB186?
The Accentra D111 is a Grade 1 single cylinder deadbolt with a 2-3/8 inch backset for doors 1-3/8 inch to 1-3/4 inch, cylinder x thumbturn. The Dexter DB1000 single cylinder is Grade 1 cylinder x thumbturn for 1-3/8 inch to 1-7/8 inch doors. The Delaney LM Series is a Grade 1 single cylinder deadbolt supplied less core in a dull chrome US26D finish. All three share the QDB186's Grade 1 rating and cylinder x thumbturn function.
12) Which heavy duty deadbolt works for a fire rated opening besides the Dormakaba QDB186?
The Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch and a cylinder x thumbturn function. The Hager 3118 Grade 1 classroom deadbolt carries a fire rating and uses a Schlage C keyway with a 6-pin cylinder. The Dormakaba QDB186 is UL and cUL listed 3 hour for A label single door applications up to 4 feet by 8 feet, and is UL10C and UL10B positive pressure rated.
13) What do I have to specify when ordering a Dormakaba QDB186 deadbolt?
Four things plus keying. Backset (2-3/4 inch standard or 2-3/8 inch), cylinder type (conventional Schlage "C", SFIC less core, or less cylinder), faceplate corners (square or round, to match the existing door edge mortise), and finish. Keying is a required selection: keyed different, keyed alike if you want a run of doors on one key, or none when you have chosen a less cylinder option.
14) Can I get several QDB186 deadbolts keyed alike for one building?
Yes, keyed alike is a standard ordering option on the QDB100 deadbolt, so a run of storage rooms or a set of tenant spaces can open on one key. Keyed different is the default. Beyond that, conventional cylinders support master keying, grand master keying and construction keying, and each conventional lockset comes with two keys. If the building already runs on small format cores, order the SFIC version less core instead and pin them into your existing system.
15) What finishes does the QDB186 deadbolt come in, and will it match the rest of my door hardware?
Five finishes: 605 bright brass, 613 oil rubbed bronze, 619 satin nickel, 625 bright chrome and 626 satin chrome. The exposed trim is solid forged brass plated to the finish designation, not a plated pot metal casting, so it holds up on an exterior or high traffic opening. Those are standard BHMA finish numbers, so 626 satin chrome will read the same as the 626 levers and closers already on your doors.
16) Do I need a Grade 1 deadbolt or will a Grade 2 do for an interior office door?
Grade 1 like the QDB100 is what you want on exterior openings, fire rated doors and anywhere the bolt is the security of record, because of the forged housing, the 1 inch throw and the anti-drill and anti-saw features. For a low traffic interior door where the bolt is convenience rather than perimeter security, a Grade 2 costs less to standardize on: the Arrow DBX61 and Dexter DB2000 are Grade 2 single cylinder deadbolts, and the Dexter is listed for 1-3/8 inch to 1-3/4 inch doors. Do not swap grades on a labeled fire door without checking the replacement carries its own listing.
17) My door has no bore at all yet. Is a bored deadbolt like the QDB186 the right choice, or should I use a mortise deadlock?
A bored bolt like the QDB100 is the faster install on a standard door: one 2-1/8 inch cross bore, a 2-3/4 inch backset and the edge mortise for the faceplate, all cuts a standard boring jig makes. Go mortise only when the door is already mortise prepped or you need the bolt integrated with a lock case, in which case the Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock for 1-3/4 inch to 2-1/4 inch doors. For an aluminum storefront stile neither of these applies; that opening takes a narrow stile deadlatch or hook bolt instead.
18) Is there a Grade 1 deadbolt with an adjustable backset instead of ordering a fixed backset?
The Falcon D111 is a Grade 1 heavy duty classroom deadbolt with an adjustable backset, which suits a mixed-prep building where the bore centers vary door to door. The Dormakaba QDB186 is ordered to a fixed backset, 2-3/4 inch or 2-3/8 inch, so the prep has to be confirmed before the order goes in. Both are cylinder x thumbturn Grade 1.
19) What deadbolt suits a residential or light commercial door where a Grade 1 heavy duty unit is more than the opening needs?
The Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn for doors 1-3/8 inch to 1-3/4 inch. The Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset over the same door range. The Bravura 310B Elite is a Grade 2 traditional round deadbolt, cylinder x thumbturn. The Dormakaba QDB186 is a Grade 1 heavy duty commercial deadbolt with an ADA compliant thumbturn.
20) What should be used instead of a Dormakaba QDB186 when the opening needs electric or keypad control rather than a key?
The DynaLock 1300 Series is a heavy duty mortise electric deadbolt for openings tied into an access control system. The Codelocks CL2210 is an electronic mortise deadbolt, and the CL2200 is a medium duty electronic surface deadbolt in a brushed steel finish. The Dormakaba QDB186 is a mechanical Grade 1 heavy duty deadbolt operated by cylinder and thumbturn, with no electrical connection.
