Stanley Security QDB284-626-S4-DBS-1 – Frequently Asked Questions

1) Is the Stanley QDB285 deadbolt fire rated for a labeled door?
It is UL/cUL listed for 3 hours on A label single door openings up to 4 feet by 8 feet, and positive pressure rated to UL10C/UBC 7-2 (1997), plus UL10B pressure rated. It also carries ANSI/BHMA A156.12 Grade 2 and meets ANSI A117.1 accessibility with an ADA compliant thumbturn, and it is Miami-Dade N.O.A. hurricane compliant.
2) What door prep does the QDB285 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) or 2-3/8 inch (60mm) backset. That is the common tubular deadbolt prep, so it retrofits most existing deadbolt holes without redrilling the face of the door. The edge bore takes the deadbolt latch, and the latch is adjustable at the point of installation.
3) Will the QDB285 latch into the deadbolt strike already in my frame?
The bolt is a full 1 inch (25.4mm) throw with a hardened steel roller, and the standard strike supplied is 1-1/8 inch x 2-3/4 inch with square corners. If your frame is cut for that same standard deadbolt strike, it lines up. Other strike options are available if your frame prep differs.
4) What does the indicator on the Stanley QDB285 actually show?
It shows from the outside whether the bolt is thrown, so someone approaching can see locked or unlocked without trying the door. That is why these turn up on rest stop and state park restrooms, storage rooms, and single-occupancy commercial spaces where a person inside throws the thumbturn.
5) Can I use my existing small format interchangeable cores with a Stanley QDB200 deadbolt?
Yes. The QDB200 series is offered with an SFIC option so you can carry over the small format cores already in your building and keep the keying system you have. There is also a SmartKey re-key option that lets you re-key the lock in the door without pulling the deadbolt off.
6) My door is 2 inches thick. Which deadbolts will actually cover that?
The QDB200 series handles it, with a range to 2 inch (51mm). Most competing tubular deadbolts we carry stop at 1-3/4 inch, including the Dexter DB2000 and Hager 3215. If you need to go thicker still, the Corbin Russwin DL3011 cylindrical deadlock is listed for 1-3/4 to 2-1/4 inch doors.
7) What is a direct equivalent to the Stanley Security QDB285 single cylinder deadbolt from another brand?
The QDB285 is a Grade 2 deadbolt with cylinder by thumbturn operation. Close equivalents by grade and function include the Arrow DBX61, a Grade 2 single cylinder deadbolt, the Dexter DB2000 Grade 2 single cylinder deadbolt for doors 1-3/8 to 1-3/4 inch thick, the Falcon D211 Grade 2 classroom function deadbolt, and the Cal-Royal CB160 Grade 2 single cylinder deadbolt with tamper-resistant cylinder guard. All four use the same cylinder by thumbturn arrangement as the QDB285.
8) I need a heavier deadbolt than a Grade 2 for a high traffic entrance - what steps up from the QDB285?
The QDB285 is rated Grade 2 for light commercial use. For a Grade 1 deadbolt in the same cylinder by thumbturn arrangement, look at the Dexter DB1000 Grade 1 single cylinder deadbolt for 1-3/8 to 1-7/8 inch doors, the Accentra D111 Grade 1 with 2-3/8 inch backset for 1-3/8 to 1-3/4 inch doors, the Falcon D111 Grade 1 heavy duty classroom deadbolt with adjustable backset, or the Delaney LM Series Grade 1 less core deadbolt in dull chrome.
9) The opening needs a key on both sides, not a thumbturn. What do I order instead of the QDB285?
The QDB285 is cylinder by thumbturn, so it will not give you key control on the inside. For double cylinder operation, the Dexter DB2000 double cylinder is Grade 2 for 1-3/8 to 1-3/4 inch doors, the Delaney LU Series is a Grade 2 double cylinder in stainless steel US32D, the Hager 3214 is a Grade 2 double cylinder with Schlage C keyway 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 your local egress code before specifying double cylinder.
10) We keep small format interchangeable cores on our master key system - which deadbolts accept an SFIC instead of the QDB285 standard cylinder?
The QDB285 series is offered with an SFIC option so existing small format cores can be reused. If you are cross-shopping, the Arrow E61 26D IC is a Grade 2 single cylinder deadlock supplied SFIC prep less core for 1-3/8 to 1-3/4 inch doors, the Deltana CL200LAIC is a Grade 2 single deadbolt with interchangeable core prep and 2-3/4 inch backset, and the Delaney LM Series Grade 1 deadbolt ships less core as well.
11) Which products look like a substitute for the QDB285 but will not drop into the same door prep?
Several deadbolts in the same shopping bracket use a different preparation. The QDB285 is a bored deadbolt using a 2-1/8 inch cross bore with a 2-3/8 or 2-3/4 inch backset. The Emtek 2050 and 2051 are European mortise deadbolts with an integrated roller latch, which need a mortise pocket. The Dormakaba D900 is a small case mortise deadbolt, and the Codelocks CL200 is a surface mounted deadbolt with key override. The Arrow 460 is a mortise lock strike, not a lock at all.
12) The door only needs to lock from the inside with no key outside - is the QDB285 right, or is there a better option?
The QDB285 is keyed from the outside and turned from the inside, so it is more lock than that opening needs. For a non-keyed exit application the Arrow E60 is a Grade 2 exit deadlock with a blank plate on the outside and a thumbturn inside, for 1-3/8 to 1-3/4 inch doors. For a single-sided application on a door with no through bore, the Callan Model 205S is a Grade 3 one sided half-bore deadbolt.
13) Our doors are 2 inches thick - which deadbolts cover that, since many stop at 1-3/4?
The QDB285 covers a door range of 1-3/8 inch to 2 inch, with service part 8Q00082 spacer rings needed at 1-3/8 inch. Among comparable deadbolts, the Deltana 7312KA2 double cylinder Grade 3 also lists 1-3/8 to 2 inch, and the Corbin Russwin DL3011 Grade 1 cylindrical deadlock covers 1-3/4 to 2-1/4 inch. Many others, such as the Dexter DB2000 and the Hager 3215, stop at 1-3/4 inch.
14) What do I have to specify when ordering the QDB285 deadbolt?
Three choices: backset (2-3/4 inch or 2-3/8 inch), latch faceplate corner style (square or round), and finish. Finishes run 605 bright brass, 613 oil rubbed bronze, 619 satin nickel, 625 bright chrome, and 626 satin chrome. The standard faceplate is 1-1/8 inch x 2-1/4 inch, with a 1 inch x 2-1/4 inch faceplate also available.
15) Is a Grade 2 auxiliary deadbolt enough for a commercial opening, or do I need Grade 1?
The QDB285 is a Grade 2, standard duty commercial deadbolt, built for light commercial work and normally paired with a cylindrical lock to add a second point of security rather than carrying the opening alone. For a high-traffic or high-abuse opening where you want Grade 1, look at the Falcon D111 or the Dexter DB1000 single cylinder deadbolt, both Grade 1 cylinder x thumbturn.
16) Is the QDB285 keyed on both sides or thumbturn inside?
Single cylinder: key outside, thumbturn inside, and the thumbturn is ADA compliant. If your code official or egress plan calls for key on both sides, this is not the right function and you would need a double cylinder unit such as the Delaney LU Series Grade 2 double cylinder deadbolt.
17) Is there a lighter duty deadbolt than the QDB285 for interior or light residential doors?
Yes. The QDB285 is a Grade 2 commercial deadbolt. Lighter options include the Cal-Royal ED500 Grade 3 single cylinder with adjustable backset for 1-3/8 to 1-3/4 inch doors, the Cal-Royal LSD Grade 3 with ADA ergonomic thumbturn for the same door range, and the Callan Model 200S Grade 3 single cylinder square trim deadbolt. All three use cylinder by thumbturn operation like the QDB285.
18) We want keyless entry on the same openings where we use the QDB285. What electronic deadbolts cover that?
The QDB285 is a keyed mechanical deadbolt with a thumbturn. For credential or code based access on a comparable opening, the Delaney KP400 is a Grade 2 electronic deadbolt with a programmable remote, the Codelocks CL2200 is a medium duty electronic surface deadbolt in brushed steel, the Codelocks CL2210 is an electronic mortise deadbolt, and the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override.
19) Our doors are keyed on a Schlage C keyway - what Grade 2 deadbolt matches that if we are comparing against the Stanley QDB285?
The QDB285 is a Grade 2 cylinder by thumbturn deadbolt offered with a SmartKey re-key option. If your system is built on Schlage C, the Hager 3115 is a Grade 2 cylinder by thumbturn deadbolt with a Schlage C keyway for 1-3/8 to 1-3/4 inch doors and carries a fire rating, and the Hager 3215 is a Grade 2 single cylinder with a 1 inch throw in the same door range. The QDB285 also uses a full 1 inch steel throw bolt.
20) We want a deadbolt plus latch in one unit rather than adding a separate QDB285 above the lockset - what does that?
The QDB285 is an auxiliary deadbolt commonly installed above a cylindrical lock for a second point of security, which means two bores and two units. If you would rather buy one assembly, the Falcon H2101 is a Grade 2 entrance interconnected lock with a single cylinder deadbolt built in. For a deadlocking function in a cylindrical body, the Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock for 1-3/4 to 2-1/4 inch doors.
21) Field crews do not always know the backset before they get to the door - which deadbolts adjust?
The QDB285 uses an adjustable backset deadbolt latch and is ordered in either 2-3/8 inch or 2-3/4 inch backset. Other adjustable options include the Falcon D111 Grade 1 deadbolt with adjustable backset, the Cal-Royal ED500 Grade 3 with adjustable backset, and the Brinks Raleigh and Mendocino single cylinder deadbolts, both with a 4-way adjustable backset.
22) How does the QDB285 resist someone attacking the lock?
Four things do the work: a full 1 inch steel throw bolt, a hardened steel roller pin in the bolt that spins against a saw blade, two ball bearings, and a free-spinning cylinder collar so a wrench cannot grab and turn the cylinder. Exposed trim is stainless steel with an iron forged cylinder guard.
23) We want a square rose to match our contemporary trim instead of the QDB285 look - what Grade 2 deadbolts offer that?
The QDB285 is ordered with either square or round face plate corners on the latch, in finishes including 605 bright brass, 613 oil rubbed bronze, 619 satin nickel, 625 bright chrome, and 626 satin chrome. If you want square exterior trim, the Bravura 310SC Elite is a Grade 2 contemporary square deadbolt, the Callan Model 200S is a Grade 3 square trim deadbolt, and the Bravura 910 is a Grade 2 rectangle single cylinder deadbolt. For round contemporary trim the Bravura 310RC Elite is Grade 2.
