Accentra YAL-D251 606 – Frequently Asked Questions

1) Does the Accentra D251 deadbolt have a thumbturn on the inside?
No. The D251 is a cylinder by blank plate deadbolt, meaning the key cylinder is on one face and a plain blank escutcheon on the other. There is no inside turn, so the bolt can only be thrown or retracted with a key from the keyed side. That makes it a storeroom-style or exterior-only application, typically a door where you do not want the bolt operated from the secure side. If you need key outside and turn inside, look at a cylinder x thumbturn deadbolt such as the Arrow DBX61 or the Dexter DB2000 single cylinder.
2) Will the Accentra D251 deadbolt fit a 1-3/8 inch door?
Yes. The D251 covers a door thickness range of 1-3/8 to 1-3/4 inches, so it handles both the older 1-3/8 inch interior doors and standard 1-3/4 inch commercial doors with the same part. Anything thicker than 1-3/4 inches is out of range.
3) What backset does the Accentra D251 deadbolt use, and will it line up with my existing cross bore?
The D251 is built for a 2-3/8 inch backset, the shorter of the two standard bored-lock backsets (2-3/4 inch is the other). If your existing bore is centered 2-3/4 inches back from the door edge, this one will not line up and you need the 2-3/4 inch version instead. Measure from the edge of the door to the center of the existing hole before ordering.
4) Will the Accentra D251 deadbolt latch into the strike already in my frame?
The D251 throws a 1 inch solid steel bolt into a standard strike measuring 2-3/8 by 1-1/8 inches (70mm x 29mm). If the existing strike in your frame matches that cutout, the new bolt drops straight in. If your frame carries a larger box strike or a full lip mortise strike, plan on re-prepping the jamb or reusing a strike that matches those dimensions.
5) Is the Accentra D251 deadbolt rated for commercial use, and what grade is it?
It carries ANSI/BHMA Grade 2 and is catalogued for commercial service. Grade 2 is the medium duty commercial tier, suited to offices, retail, multi-tenant residential and similar traffic. If your spec calls for Grade 1 on the opening, a cylindrical deadlock like the Corbin Russwin DL3211 is the heavier equivalent, though that one is built for 1-3/4 inch doors only.
6) I need a thumbturn on the inside, not a blank plate - what Grade 2 deadbolt should I order instead of the Accentra D251?
The D251 is a cylinder x blank plate function, so there is no inside operator at all; it is keyed outside and smooth inside. For a Grade 2 deadbolt with an inside thumbturn, the Falcon D211 is a Grade 2 cylinder x thumbturn deadbolt, the Dexter DB2000-SCT is a Grade 2 single cylinder deadbolt with thumbturn covering 1-3/8 inch to 1-3/4 inch doors, and the Hager 3215 is a Grade 2 single cylinder deadbolt with a 1 inch throw over the same 1-3/8 inch to 1-3/4 inch thickness range. Any of the three drops into an opening where egress needs to be possible without a key.
7) Is there a version of the Accentra D251 that takes a small format interchangeable core?
The D251 is a single cylinder deadbolt supplied as a cylinder x blank plate. If the facility is keyed on an SFIC system and the core is to be loaded in the field, the Arrow E61 in 26D is a Grade 2 single cylinder deadlock prepped for SFIC and shipped less core, rated for 1-3/8 inch to 1-3/4 inch doors, which matches the D251 thickness range.
8) My spec calls for a fire rated deadbolt - does the Accentra D251 cover that or do I need something else?
The D251 is a Grade 2 cylindrical deadbolt with a 1 inch solid steel throw for commercial openings. Where the drawing calls out a fire rating on the deadbolt itself, the Hager 3215 is a Grade 2 single cylinder deadbolt with a 1 inch throw carrying a fire rating and covering 1-3/8 inch to 1-3/4 inch doors, and the Hager 3118 is the Grade 1 classroom deadbolt with a fire rating, a Schlage C keyway and a 6-pin cylinder over the same thickness range.
9) The doors on my job are drilled for a 2-3/4 inch backset - can I still use the Accentra D251?
No. The D251 is built to a 2-3/8 inch backset with a 2-3/8 inch by 1-1/8 inch standard strike. For an existing 2-3/4 inch bore, the Deltana CL200LA is a Grade 2 single cylinder deadbolt with a 2-3/4 inch backset, and the Deltana CL200LAIC is the same Grade 2 deadbolt prepped for an interchangeable core. Deadbolts with adjustable backsets, such as the Cal-Royal ED500, also cover the 2-3/4 inch condition.
10) Do I have to order the Accentra D251 deadbolt left hand or right hand?
Handing is not a concern. The D251 is non-handed and field reversible, so one part number covers both left and right hand doors and you can set it at the opening. For a property manager stocking spares across a building, that means one SKU per finish rather than two.
11) What is the difference between the Accentra D251 deadbolt and a surface mounted electronic deadbolt?
The D251 is a cylindrical bored deadbolt, so it installs through a cross bore in the door face and an edge bore, and it is keyed mechanical only. A surface deadbolt like the Codelocks CL200 with key override mounts on the face of the door rather than boring it, and the Codelocks CL2200 is an electronic surface deadbolt. Choose the D251 when the door is already bored for a cylindrical lock and you want mechanical keyed security; choose surface mount when you would rather not cut the door or you need code entry.
12) The opening does not need to be keyed at all - just a deadbolt thrown from inside. What replaces the Accentra D251 there?
The D251 is keyed on the outside and blank on the inside, which is the opposite arrangement. For a non-keyed opening thrown from the inside only, the Arrow E60 is a Grade 2 exit deadlock in a blank plate x thumbturn function, rated for 1-3/8 inch to 1-3/4 inch doors - the same thickness range the D251 covers. Another one-sided option is the Callan 205S, a Grade 3 one-sided half-bore deadbolt, which requires only a partial bore rather than a through-bore.
13) If the door needs to be keyed from both sides, what do I use instead of the Accentra D251?
The D251 is a single cylinder function, keyed one side only. For key operation from both faces, the Hager 3214 is a Grade 2 double cylinder deadbolt with a Schlage C keyway, rated for 1-3/8 inch to 1-3/4 inch doors, and the Dexter DB2000-DCT is a Grade 2 double cylinder deadbolt over the same thickness range. For a Grade 1 double cylinder, the Design Hardware D1 Series is an extra heavy duty Grade 1 double cylinder deadbolt for 1-3/4 inch doors. Confirm local egress code before specifying double cylinder on an occupied space.
14) What is a lighter duty alternative to the Accentra D251 for a low traffic interior door?
The D251 is certified ANSI/BHMA Grade 2 for commercial use. For lower traffic openings, the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset, and the Cal-Royal LSD is a Grade 3 single cylinder deadbolt with an ADA ergonomic thumbturn; both are rated for 1-3/8 inch to 1-3/4 inch doors, the same range as the D251. Note that both Grade 3 units are cylinder x thumbturn, so they put an inside operator on the door where the D251 leaves a blank plate.
15) Can I use the BEST 8T tubular deadbolt tube or a Baldwin deadbolt spacer in place of the Accentra D251?
No - neither is a complete lock. The Accentra D251 is a full cylindrical deadbolt with a 1 inch solid steel throw, a cylinder outside and a blank plate inside. The BEST 8T is the tube component of a T Series tubular deadbolt, and the Baldwin 8BR0618001 is a deadbolt spacer for a double cylinder assembly. Both are pieces that go into or alongside another lock, not a standalone replacement for the D251. The Arrow 460 is likewise a mortise lock strike for latchbolt and deadbolt functions, not a deadbolt.
16) What are my options if I want keypad or credential access instead of the keyed Accentra D251?
The D251 is a mechanical single cylinder deadbolt operated by key. For electronic operation, 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, and the Dormakaba Saffire LX-D is an RFID electronic deadbolt with BLE and electronic lock override. Surface-mounted electronic deadbolts such as the CL2200 mount to the face of the door rather than into a 2-3/8 inch bore, so the door prep differs from the D251.
17) My classroom spec calls for a deadbolt keyed both sides or classroom function - is the Accentra D251 it?
The D251 is a cylinder x blank plate function, meaning it locks and unlocks by key from the outside with no inside operator, which is not a classroom function. For classroom deadbolts, the Falcon D111 is a Grade 1 classroom deadbolt with an adjustable backset and the Falcon D211 is the Grade 2 classroom function with single cylinder operation. The Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and a 6-pin cylinder for 1-3/8 inch to 1-3/4 inch doors.
18) What finishes does the Accentra D251 deadbolt come in for matching existing hardware?
Eight finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613E dark oxidized satin bronze equivalent, 619 satin nickel, 625 bright chrome, 626 satin chrome, and BSP black suede powder coat. For a building already standardized on 626 satin chrome, which is the common commercial default, the D251 matches without special order.
19) Is the Accentra D251 handed, and how does that compare with other commercial deadbolts?
The D251 is non-handed and field reversible, so one part number serves both left and right hand openings across all eight finishes it is offered in, from 605 bright brass to BSP black suede powder coat. Among comparable commercial deadbolts, the Arrow E60 Grade 2 exit deadlock and the Falcon D211 Grade 2 deadbolt are likewise ordered by function rather than by hand. Handing becomes a factor only when moving to a mortise lock body, such as the one the Arrow 460 strike serves.
