Schlage B663P 626 – Frequently Asked Questions

1) What does classroom function mean on a Schlage B663 deadbolt?
On the B663, the key throws and retracts the bolt from the outside, but the inside thumbturn only retracts it. Nobody inside can lock the door; that takes the key from the corridor side. It's the E0171 function in Schlage's B600 lineup. In practice a teacher or staff member keys the door locked from the hall, and anyone inside can still get out by turning the thumbturn. If you want a thumbturn that both locks and unlocks, that's the B660 (E0151) instead.
2) Is the Schlage B663 still Grade 1 if I order it with an interchangeable core?
No, and this catches people out on spec jobs. The B600 deadbolt is ANSI/BHMA A156.5 Grade 1 only with the conventional cylinder. Order it FSIC and it certifies Grade 2; order it SFIC and it's Grade 3. If your drawing calls for Grade 1 deadbolts, specify the P6 conventional 6-pin cylinder, not the B or J less-core options.
3) Can I use a Schlage B663 deadbolt on a fire rated door?
The B Series deadbolts are UL 10C listed and 3-hour fire rated as auxiliary locks on A label single doors up to 4' x 8', plus UL 10B listed for neutral pressure doors. Auxiliary is the operative word: it's the second lock on the opening, not the latching device that holds the door closed.
4) Will the B663 drop into my existing deadbolt prep and strike?
Standard tubular prep, yes. The bolt housing is 1 inch diameter with a 2-3/4 inch backset, the faceplate is 1-1/8 x 2-1/4 inches square corner, and the strike is 1-1/8 x 2-3/4 inches square corner. Bolt throw is 1 inch. If your existing prep is a 2-3/8 inch backset, the fixed-backset B663 won't line up, though Schlage's 12-296 adjustable latch covers 2-3/8 or 2-3/4. Round corner, ANSI and thimble strikes are also available if the frame is prepped differently.
5) What do I have to specify when ordering a Schlage B663 classroom deadbolt?
Four things. Cylinder: P6 conventional 6-pin C keyway, J for FSIC less core, or B for SFIC less core. Finish: 605 bright brass, 606 satin brass, 609 antique brass, 612 satin bronze, 613 oil rubbed bronze, 619 satin nickel, 622 matte black, 625 bright chrome, 626 satin chrome, 626AM satin chrome antimicrobial, or 643E aged bronze. Keying: keyed different (standard), keyed alike for multiple locks, or none if you're taking it less cylinder. Keyway: C standard or S123. Keyed locks ship with two cut keys.
6) The Schlage B663 will not fit my door thickness - what Grade 1 deadbolt goes on a thicker door?
The B663 covers 1-5/8 to 2 inch with conventional and FSIC cylinders and 1-3/4 to 2 inch with SFIC. For a thicker door, the Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock rated 1-3/4 to 2-1/4 inch, built cylinder x blank. Going the other direction, on a thin door the Dexter DB1000 single cylinder is Grade 1 cylinder x thumbturn covering 1-3/8 to 1-7/8 inch, and the Accentra D111 is a Grade 1 cylinder x thumbturn deadbolt for 1-3/8 to 1-3/4 inch doors on a 2-3/8 inch backset.
7) What is the closest Grade 1 classroom-function deadbolt to the Schlage B663 from another manufacturer?
The Falcon D111 is the nearest equivalent: it is a Grade 1 classroom deadbolt in the D100 Series with cylinder x thumbturn function and a heavy duty rating, matching the B663's Grade 1 classroom function and heavy duty level. The difference is backset - the Falcon D111 uses an adjustable backset, while the B663 is built on a 2-3/4 inch fixed backset with the 12-296 adjustable deadbolt latch offered as the standard latch option. The Hager 3118 is a second Grade 1 classroom deadbolt, and it is cut for the Schlage C keyway with a 6-pin cylinder, the same keyway family as the B663's 6-pin conventional C keyway cylinder, so it can be brought onto an existing Schlage key system.
8) Which deadbolts carry classroom function besides the Schlage B663, and how do they differ?
Three others hold classroom function. The Falcon D111 is Grade 1 with cylinder x thumbturn operation. The Falcon D211 is the Grade 2, medium duty version of the same classroom function with single cylinder operation. The Corbin Russwin DL2211 is a Grade 1 cylindrical deadlock with classroom function, built cylinder x blank for a 1-3/4 inch door - meaning no inside thumbturn at all, where the B663 gives you a thumbturn that retracts the bolt only. That inside-trim difference is the one that matters: if the classroom side needs an occupant to be able to withdraw the bolt without a key, the thumbturn versions are the ones that do it.
9) Which deadbolts take an interchangeable core like the Schlage B663 less-core options?
The B663 is offered in SFIC less core and FSIC less core builds alongside the 6-pin conventional cylinder. Among other brands, the Arrow E61 is a Grade 2 single cylinder deadlock with SFIC prep less core for 1-3/8 to 1-3/4 inch doors, the Deltana CL200LAIC is a Grade 2 interchangeable core single deadbolt on a 2-3/4 inch backset, and the Delaney LM Series is a Grade 1 single cylinder less core deadbolt with cylinder x thumbturn function in dull chrome US26D. Of those, the Delaney LM is the one that also matches the B663's Grade 1 rating.
10) What should I order instead of the Schlage B663 if the opening needs a key on both sides?
The B663 is a single cylinder lock - cylinder outside, thumbturn inside that retracts the bolt only. For key-both-sides, 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 double cylinder is Grade 1 for 1-3/8 to 1-7/8 inch doors. The Hager 3214 is a Grade 2 double cylinder deadbolt cut for the Schlage C keyway, fitting 1-3/8 to 1-3/4 inch doors with a fire rating. Note that double cylinder deadbolts require no key retained inside for egress, so confirm the code path for the opening before specifying one.
11) Is a Grade 2 deadbolt like the Arrow DBX61 or Cal-Royal CB160 an acceptable swap for a Schlage B663?
They are not equivalents on rating. The Arrow DBX61 is a Grade 2 single cylinder deadbolt with cylinder x thumbturn function, and the Cal-Royal CB160 is a Grade 2 single cylinder deadbolt with a tamper-resistant cylinder guard, also cylinder x thumbturn. The Schlage B663 is Grade 1 and heavy duty, and it carries classroom function - the thumbturn retracts the bolt but does not project it. Neither Grade 2 unit is listed with classroom function, so on an opening where the spec calls for a Grade 1 classroom deadbolt, they are a different product doing a different job. For a Grade 1 substitute that keeps the function, the Falcon D111 is the match.
12) Does the Cal-Royal CRB800 do the same job as a Schlage B663?
The Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch and cylinder x thumbturn function, so it lines up with the B663 on rating - the B663 is Grade 1, heavy duty, and UL 10C listed 3-hour fire rated as an auxiliary lock. Where they part is function: the B663 is a classroom deadbolt, meaning the inside thumbturn retracts the bolt only and the bolt must be thrown by key from the corridor side. The CRB800 is a standard single cylinder deadbolt. Specify the CRB800 where a conventional single cylinder is wanted and the B663 where the classroom restriction is on the door schedule.
13) If I order the B663 less core, what cylinder do I need to add?
The B and J options ship without a core, so you supply it. J is FSIC prep, taking a Schlage full size interchangeable core; B is SFIC prep, taking a small format core. Either one lets you pull the deadbolt onto an existing IC master key system without factory keying. Order P6 instead and you get a 6-pin conventional brass cylinder in the C keyway, keyed different, with two keys, ready to hang.
14) Can I get several Schlage B663 deadbolts keyed alike across a building?
Yes. Keyed alike is an ordering option alongside the standard keyed different, and factory master keying is available on the B Series. The B600 accepts all three cylinder formats (conventional, FSIC and SFIC), so it can join whatever key system the building already runs, and it suites with nearly all Schlage and Von Duprin hardware if you're standardizing openings.
15) Is the B663 secure enough for an exterior commercial door?
It's built for it. Heavy duty, commercial rated, with a sintered steel bolt carrying a hardened steel anti-saw pin and a thicker cross section than most Grade 1 deadbolts. Hardened steel ball bearings block drilling of the mounting bolts, the free spinning angled collar defeats wrenching, and a removable shield covers the bolt against ice-pick attack through the door. On a wood frame the metal dust box anchors with three 3 inch screws into the framing, which is what actually resists a kick-in.
16) What's the difference between the Schlage B663 and the Falcon D111 classroom deadbolt?
Both are Grade 1 heavy duty classroom-function deadbolts, so either satisfies a Grade 1 spec. The split is backset: the B663 is fixed at 2-3/4 inches, while the Falcon D111 has an adjustable backset, which matters when you're replacing existing hardware and the prep is 2-3/8. The Schlage's advantage is the key system, since the B600 suites with nearly all Schlage and Von Duprin hardware. If the building is already on Schlage keys, stay with the B663.
17) Is there a Grade 1 classroom deadbolt that takes a Schlage C keyway without buying Schlage?
The Hager 3118 is a Grade 1 classroom deadbolt built for the Schlage C keyway with a 6-pin cylinder, fire rated, covering 1-3/8 to 1-3/4 inch doors. It keys into the same C keyway system as the B663's standard P6 cylinder. The door range is the practical difference: the Hager stops at 1-3/4 inches, while the B663 with a conventional cylinder runs 1-5/8 to 2 inches, so a thicker door or a door with a heavy applied finish points back to the Schlage.
18) Does the Schlage B663 meet ADA and Buy American requirements?
Both. The thumbturn is an ADA compliant design, which matters because on a classroom function that turn is the egress control, and the B600 deadbolts are Buy American Act compliant, so they clear federal and most public-institution procurement rules.
19) Which Schlage B600 deadbolt do I order if I don't want a thumbturn on the inside?
The B664 (E0101) is the cylinder lock, key outside and no inside trim at all. The B662 (E0141) is double cylinder, keyed both sides, for glazed doors where someone could reach the turn. The B663 classroom keeps an inside thumbturn but restricts it to retracting only. The B661 (E0161) is a blank rose outside face with the cylinder, and the B680 (E0191) is the keyless door bolt, thumbturn with no exterior trim. Check your local egress code before putting a double cylinder on an occupied space.
20) What is a lighter-duty alternative to the Schlage B663 classroom deadbolt for a lower-traffic opening?
The Falcon D211 is the step-down that keeps the function: Grade 2, medium duty, classroom function, single cylinder operation. If classroom function is not required and a plain single cylinder deadbolt will do, the Hager 3115 is a Grade 2 cylinder x thumbturn deadbolt on the Schlage C keyway - the same keyway family as the B663's C keyway cylinder - fitting doors 1-3/8 to 1-3/4 inch and carrying a fire rating. The B663 itself is Grade 1 and heavy duty.
21) I need a deadbolt with no key at all on the inside egress side - what replaces the Schlage B663?
The B663 always includes an exterior cylinder as a keyed single cylinder lock. If the opening needs thumbturn-only operation with no exterior keying, the Arrow E60 is a Grade 2 non-keyed exit deadlock, blank plate outside x thumbturn inside, for 1-3/8 to 1-3/4 inch doors. Within Schlage's own B600 range, the B680 door bolt is the keyless function, thumbturn with no exterior trim. The reverse case - keyed outside with nothing on the inside - is the B664 cylinder lock function.
22) Can I put a Deltana CL200LM or Delaney LM Series deadbolt on the same key system as my Schlage B663 locks?
Both are Grade 1 single cylinder deadbolts with cylinder x thumbturn function - the Deltana CL200LM and the Delaney LM Series, the latter supplied less core in dull chrome US26D. Neither is listed with the Schlage keyway, so keying them into an existing Schlage system is a cylinder question, not a lock question. The deadbolts that state keyway compatibility directly are the Hager units: the 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway 6-pin cylinder and the 3215 is a Grade 2 single cylinder with a 1 inch throw, both fitting 1-3/8 to 1-3/4 inch doors. The B663 itself ships with a 6-pin conventional C keyway cylinder and two keys.
23) What is the difference between the Schlage B663 and a mortise deadbolt like the Dormakaba D900?
The B663 is a bored tubular deadbolt: 1 inch housing diameter, 2-3/4 inch fixed backset, 1-1/8 by 2-1/4 inch square corner faceplate, going into a bored door prep. The Dormakaba D900 is a small case mortise deadbolt with cylinder x thumbturn function, keyed different with SC keyways, and the Dormakaba M1960 is a M1000 Series single cylinder deadbolt, cylinder x turn, no trim. A mortise unit needs a pocket cut into the door edge, so it is not a drop-in for a bored prep and vice versa - match the substitute to the prep already in the door.
24) Is an electronic deadbolt a substitute for the Schlage B663 on a classroom door?
They solve different problems. The B663 is a non-electronic Grade 1 mechanical classroom deadbolt keyed to a 6-pin conventional cylinder. Electronic options include the Delaney KP400, a Grade 2 electronic deadbolt with programmable remote, the Codelocks CL2200 electronic surface deadbolt in brushed steel at medium duty, and the Dormakaba Saffire LX-D RFID electronic deadbolt with BLE and electronic lock override. None of those carries classroom function, and the Codelocks CL200 surface deadbolt with key override is light duty. Where the door schedule calls for Grade 1 classroom, the mechanical unit is what meets it; the electronic units suit openings where credential control matters more than the grade.
25) Which residential-style deadbolts look like the Schlage B663 but are not rated for a commercial opening?
Several single cylinder deadbolts share the B663's cylinder x thumbturn function but sit at a lower grade. The Cal-Royal ED500 and Cal-Royal LSD are Grade 3, both for 1-3/8 to 1-3/4 inch doors, the LSD with an ADA ergonomic thumbturn. The Callan Model 200S is Grade 3 with square trim and the Callan 200S-G2 is the Grade 2 round trim version. The Bravura 310B Elite, 310RC Elite and 310SC Elite are Grade 2 in traditional round, contemporary round and contemporary square trim. The B663 is a commercial Grade 1 heavy duty lock, so on a spec that names Grade 1 none of these substitute - they are the right answer only where the grade is open.
26) My opening needs an adjustable backset - what takes the place of the Schlage B663?
The B663 is built on a 2-3/4 inch fixed backset, with the 12-296 deadbolt latch listed as the standard latch and adjustable 2-3/8 or 2-3/4 inch options available. If you would rather order a lock that ships adjustable, the Falcon D111 is a Grade 1 heavy duty classroom deadbolt with an adjustable backset - the closest match on both grade and function. The Cal-Royal ED500 is a Grade 3 single cylinder with adjustable backset for 1-3/8 to 1-3/4 inch doors, and the Brinks Raleigh E2401 and Mendocino E2402 are single cylinder deadbolts with 4-way adjustable backsets in round and square trim.
27) I searched for a Schlage B663 replacement and found the Arrow 460 and the BEST 8T - are those deadbolts?
Neither is a complete deadbolt. The Arrow 460 is a mortise lock strike with a straight lip, cut for latchbolt and deadbolt functions on a 1-3/4 inch door - a strike, not a lock. The BEST 8T is a T Series tubular deadbolt tube component, the bolt assembly on its own. The Baldwin 8BR0618001 is a deadbolt spacer for a double cylinder application. The B663 is supplied as a complete lock with the 10-094 square corner strike and the 12-296 deadbolt latch, plus two cut keys. Order the component parts only when you are servicing an existing lock, not when you are replacing one.
28) How far does the Schlage B663 trim ring stand off the door face?
The collar sits shallow, 7/8 inch deep, in solid brass or bronze with a broadly angled profile that spins free to resist wrenching. That 7/8 inch matters where a storm door, a closer arm, or a pull is close to the bolt location.
29) Is there an antimicrobial finish on the Schlage B663 for a healthcare facility?
Yes, 626AM satin chrome antimicrobial is one of the finish choices, and it's offered across all three cylinder formats: conventional P6, FSIC less core, and SFIC less core. The rest of the range is 605, 606, 609, 612, 613, 619, 622, 625, 626 and 643E.
