Dormakaba QDB282-626-S4-DBS-SC – Frequently Asked Questions

1) Will the Dormakaba QDB282 double cylinder deadbolt fit a 1-3/8 inch door?
Yes, but not out of the box. The QDB200 series covers 1-3/8 inch (35mm) through 2 inch (51mm) doors, and a 1-3/8 inch door needs the 8Q00082 spacer rings. Order those with the deadbolt if you are working on older interior doors; anything from 1-3/4 inch up to 2 inches installs without them.
2) What door prep does the Dormakaba QDB282 deadbolt need, and will it drop into an existing bore?
Standard prep: a 2-1/8 inch (54mm) diameter cross bore with a 2-3/4 inch (70mm) square backset, which is the common commercial deadbolt prep. A 2-3/8 inch (60mm) backset version is orderable for doors bored that way. The latch faceplate is 1-1/8 x 2-1/4 inches standard, with a 1 x 2-1/4 inch faceplate available, and you can pick square or round corners to match the mortise already cut in the edge of the door.
3) Will the QDB282 deadbolt latch into the strike already in my frame?
It throws a full 1 inch (25.4mm) bolt with a hardened steel roller, and ships with a 1-1/8 x 2-3/4 inch square corner deadbolt strike. If your frame is already prepped for that standard strike size, it drops straight in. A 1 inch throw needs a strike pocket deep enough to take it, so on a frame cut for a shorter residential bolt plan on re-cutting the pocket. Other strike options are available if your frame prep differs.
4) Should I use a double cylinder deadbolt or a cylinder x thumbturn on a commercial door?
Double cylinder means key on both sides, which is what the QDB282 is. Use it where the door has glass beside or in it and a thumbturn could be reached from outside. The trade-off is egress: with no thumbturn nobody leaves without a key, and most building codes restrict that on required exit doors, so check the occupancy before you specify it. If you need key outside and free egress inside, the same QDB200 platform is where a cylinder x thumbturn function belongs, and comparable Grade 2 thumbturn deadbolts include the Dexter DB2000 and the Falcon D211.
5) Is there a fire rated alternative to the Dormakaba QDB282 for a labeled opening?
The QDB282 is UL/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. On the alternative side, Hager carries a fire rating on the 3214 Grade 2 double cylinder, the 3215 and 3115 Grade 2 single cylinder units, and the Grade 1 3118 classroom deadbolt. Cal-Royal's CRB800 is a heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch. Of these only the Hager 3214 keeps the keyed-both-sides function of the QDB282.
6) We run a Best or SFIC key system - which deadbolts take our existing small format cores instead of the Dormakaba QDB282?
The QDB282 is available as an SFIC version prepped for a small format core with no core included, so existing cores drop straight in. If you are cross-shopping, the Arrow E61 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 interchangeable core deadbolt with a 2-3/4 inch backset. Both of those are single cylinder, so on an opening that must be keyed from both sides the SFIC QDB282 is the one that keeps the double cylinder function.
7) Our doors are 2 inches thick - which deadbolts cover that besides the Dormakaba QDB282?
The QDB282 covers 1-3/8 inch through 2 inch doors, with spacer rings needed at 1-3/8 inches. Among the alternatives, the Deltana 7312KA2 double cylinder deadbolt also lists 1-3/8 inch to 2 inch, and the Corbin Russwin DL3011 deadlock reaches 1-3/4 inch to 2-1/4 inch, though the DL3011 is a cylinder x blank configuration rather than keyed both sides. Most of the other Grade 2 double cylinder options stop at 1-3/4 inch, including the Hager 3214 and the Dexter DB2000.
8) What is the closest equivalent to the Dormakaba QDB282 double cylinder deadbolt from another manufacturer?
The QDB282 is a Grade 2 double cylinder deadbolt for commercial openings. The Hager 3214 is a Grade 2 double cylinder deadbolt built around a Schlage C keyway, which matches the Schlage C conventional cylinder the QDB282 offers, and Hager lists it for 1-3/8 inch to 1-3/4 inch doors. The Dexter DB2000 double cylinder is also Grade 2 and covers a 1-3/8 inch to 1-3/4 inch door range. Either one lands in the same grade and function as the QDB282; the QDB282 covers doors up to 2 inches with spacer rings at 1-3/8 inches.
9) I need a heavier deadbolt than the Dormakaba QDB282 for a high traffic entrance - what steps up?
The QDB282 is Grade 2 standard duty. For a heavier opening, the Design Hardware D1 Series is a Grade 1 extra heavy duty double cylinder deadbolt for 1-3/4 inch doors, and the Dexter DB1000 is a Grade 1 double cylinder deadbolt covering 1-3/8 inch to 1-7/8 inch doors. Both keep the double cylinder function - key on both sides, no thumbturn - so the operation on the door does not change, only the ANSI grade and duty rating.
10) The fire marshal will not allow a double cylinder deadbolt on our egress door - what single cylinder deadbolt do I use instead?
A double cylinder deadbolt like the Dormakaba QDB282 takes a key on both sides, which is what egress review objects to. A cylinder x thumbturn deadbolt keys the outside and turns free from the inside. In the same Grade 2 band, the Dexter DB2000 single cylinder covers 1-3/8 inch to 1-3/4 inch doors, the Arrow DBX61 is a Grade 2 single cylinder deadbolt, and the Hager 3215 is a Grade 2 cylinder x thumbturn with a 1 inch throw - the same 1 inch throw the QDB282 carries. Falcon's D211 is a Grade 2 medium duty cylinder x thumbturn if you want a classroom function on the same door.
11) Will a Corbin Russwin DL3011 or DL3211 deadlock work in place of a Dormakaba QDB282?
Not as a like-for-like swap. The QDB282 is a double cylinder deadbolt, keyed on both faces, with a 2-1/8 inch cross bore and a 2-3/4 inch or 2-3/8 inch backset. The Corbin Russwin DL3011 and DL3211 are Grade 1 cylindrical deadlocks in a cylinder x blank configuration - one keyed face and a blank plate on the other - so the inside face gives no key operation at all. The DL3011 is listed for 1-3/4 inch to 2-1/4 inch doors and the DL3211 for 1-3/4 inch doors, both narrower at the thin end than the QDB282 range. Use them where the interior side is intentionally dead, not where you need key control from both sides.
12) We key everything to Schlage C - which deadbolts besides the Dormakaba QDB282 come on that keyway?
The QDB282 is offered with a conventional cylinder in the Schlage C keyway, so it pins into an existing SC system directly. The Hager 3214 double cylinder deadbolt is also built on a Schlage C keyway, as are the Hager 3215 single cylinder and the Hager 3115 cylinder x thumbturn, both Grade 2. The Hager 3118 is a Grade 1 classroom deadbolt on Schlage C with a 6-pin cylinder if the facility standard calls for 6-pin.
13) What do I have to specify when ordering a Dormakaba QDB282 deadbolt?
Five decisions. Backset, 2-3/4 or 2-3/8 inch. Cylinder type: conventional Schlage C keyway, SFIC less core, or less cylinder. Faceplate corners, square or round. Finish: 605 bright brass, 613 oil rubbed bronze, 619 satin nickel, 625 bright chrome, or 626 satin chrome. And keying, either keyed different, keyed alike if you want one key across several units, or none when you are going less cylinder. Match the backset and corner style to the door you already have and the rest is preference.
14) I need the same deadbolt on twenty units keyed to one key. Can the QDB200 be ordered that way?
Keyed alike is a selectable option, so a run of QDB282 deadbolts can come keyed to a single key rather than the standard keyed different. For a property where you expect to change tenants, the SmartKey re-key option lets the lock be re-keyed in the door without pulling it off, and the SFIC version lets you swap cores instead. Keep the backset, faceplate corner style and finish consistent across the order so the units all prep and look the same.
15) Is a Grade 2 deadbolt enough for a light commercial door, or do I need Grade 1?
Grade 2 standard duty is what the QDB200 series is built and certified to, and Dormakaba positions it for light commercial work: storage rooms, park and rest stop restrooms, offices, and residential openings, usually alongside a cylindrical lockset for a second layer. For high traffic or high abuse openings, step up to a Grade 1 deadbolt such as the Design Hardware D1 Series double cylinder or the Dexter DB1000 double cylinder, which covers 1-3/8 to 1-7/8 inch doors.
16) What other double cylinder deadbolts could I use instead of the Dormakaba QDB282?
For a like-for-like Grade 2 double cylinder, the Delaney LU Series in stainless steel (US32D) and the Dexter DB2000 double cylinder, rated for 1-3/8 to 1-3/4 inch doors, are the closest peers. Stepping up in grade, the Design Hardware D1 Series is a Grade 1 extra heavy duty double cylinder for 1-3/4 inch doors. Going the other way, the Callan 210S is a Grade 3 double cylinder. On a decorative opening the Baldwin Reserve contemporary round and square double cylinder deadbolts and the Emtek 8323 Disc are the trim-driven choices.
17) Is there a lighter or more economical double cylinder deadbolt than the Dormakaba QDB282?
The QDB282 is Grade 2 and rated for commercial use. If the opening does not need that, the Callan Model 210S is a Grade 3 double cylinder deadbolt and the Deltana 7312KA2 is a Grade 3 double cylinder that covers 1-3/8 inch to 2 inch doors - the same door range the QDB282 spans. Grade 3 is the residential-duty tier of ANSI/BHMA, so it is a step below the Grade 2 cycle and strength testing the QDB282 is certified to under A156.12.
18) What is another Grade 2 double cylinder deadbolt if I need a specific finish the Dormakaba QDB282 does not come in?
The QDB282 is offered in 605 bright brass, 613 oil rubbed bronze, 619 satin nickel, 625 bright chrome and 626 satin chrome. If the job calls for a different finish, the Delaney LU Series is a Grade 2 double cylinder deadbolt supplied in US32D stainless steel, and the Hager 3214 is a Grade 2 double cylinder on the Schlage C keyway. Both hold the same double cylinder function, so the change is trim appearance rather than how the door operates.
19) Can I use a Codelocks CL200 surface deadbolt or a Baldwin Reserve deadbolt instead of a Dormakaba QDB282?
They look like substitutes and are not. The Codelocks CL200 is a light duty surface deadbolt with key override - it mounts on the face of the door rather than through a 2-1/8 inch cross bore, so it does not use the QDB282 prep, and it is rated light duty against the QDB282 standard duty commercial rating. The Baldwin Reserve DC.CRD and DC.CSD are double cylinder deadbolts, which matches the function, but they are residential decorative trim rather than a commercial Grade 2 unit. For a bored commercial opening keyed both sides, stay with a Grade 2 bored double cylinder such as the Hager 3214 or Dexter DB2000.
20) The restroom door needs to lock from the inside only - is the Dormakaba QDB282 right, or is there a better deadbolt?
The QDB282 is keyed on both sides, so an occupant needs a key to secure it - wrong for a restroom or store room that locks from within. The Arrow E60 is a Grade 2 exit deadlock, non-keyed, with a blank plate on one face and a thumbturn on the other for 1-3/8 inch to 1-3/4 inch doors, which is the pattern for that use. The Callan Model 205S is a Grade 3 one-sided half-bore deadbolt where only one face gets trim at all.
21) Which deadbolts have an adjustable backset if I am not sure whether the doors are 2-3/8 or 2-3/4?
The Dormakaba QDB282 handles this by supplying an adjustable backset deadbolt latch, and it is ordered in either 2-3/4 inch or 2-3/8 inch. Among the alternatives, the Falcon D111 is a Grade 1 heavy duty classroom deadbolt with adjustable backset, the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with adjustable backset for 1-3/8 inch to 1-3/4 inch doors, and the Brinks Raleigh E2401 uses a 4-way adjustable backset. All three of those are cylinder x thumbturn rather than keyed on both faces.
22) What is the difference between the Dormakaba QDB282 and an electronic deadbolt like the Codelocks CL2200 or Delaney KP400?
The QDB282 is a mechanical double cylinder deadbolt - a key opens it from either face, with no power, no batteries and no code. The Codelocks CL2200 is a medium duty electronic surface deadbolt, the CL2210 is an electronic mortise deadbolt, and the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote. Those give credential or code entry and change the door prep and the maintenance picture; the QDB282 stays inside a standard bored prep with a 2-1/8 inch cross bore and keys into an existing key system.
23) What is the QDB282 deadbolt made of, and how does it hold up to attack?
Exposed trim is stainless steel with an iron forged cylinder guard. Against attack it uses a full 1 inch steel throw bolt with a hardened steel roller pin, two ball bearings, and a free spinning cylinder collar, which is aimed at saw, drill and wrench attempts. That free spinning collar is the detail that matters on an exterior opening: a wrench gets no purchase on the cylinder.
24) Which finish of the Dormakaba QDB200 deadbolt matches the levers already on my building?
Five BHMA finishes are offered: 605 bright brass, 613 oil rubbed bronze, 619 satin nickel, 625 bright chrome, and 626 satin chrome. On most commercial jobs the existing hardware is 626 satin chrome, so that is the usual match. If your other openings are polished, 625 bright chrome pairs with them; 605 and 613 are the ones to pick when the building runs brass or dark bronze trim.
25) Can a keyed deadbolt like this go on a restroom or storage room door where staff need to see if it is occupied?
The QDB200 series is offered with an indicator that shows locked or unlocked from the exterior, and rest stop and park restrooms and storage rooms are exactly the applications Dormakaba calls out for it. Note that a double cylinder version needs a key from inside to get out, so for an occupied restroom you generally want the indicator paired with a function that gives free egress rather than key on both sides.
