Schlage B581626 – Frequently Asked Questions

1) Does the Schlage B581 deadbolt have a key or a thumbturn on the outside of the door?
Neither. The B581 is a one-sided deadbolt: the inside thumbturn throws and retracts the bolt, and the outside face is a blank plate with no cylinder and no turn. Once fully thrown, the bolt deadlocks automatically. That makes it the part for openings you want secured from one side only, storage and mechanical rooms, back-of-house doors, or an interior door locked down after hours. If someone has to get in from the outside with a key, the keyed functions in the same B500 family are the B560 (thumbturn and cylinder), the B561 (blank rose and cylinder), and the B562 (cylinder both sides).
2) Will a Schlage B581 deadbolt fit a 1-3/4 inch commercial door?
Yes. Thumbturn-only B500 Series deadbolts cover doors from 1-3/8 to 1-7/8 inches thick, so a 1-3/4 inch commercial door sits in the middle of that range, and the 1-3/8 inch doors common on older interior openings are covered at the bottom end. No spacer or thick-door kit is involved anywhere in that span.
3) What backset does the Schlage B581 use, and will it line up with the deadbolt hole already in my door?
Backset is adjustable between 2-3/8 and 2-3/4 inches, the two bores you find in the field, and the helix design locks it in place once set, so one part covers either existing prep. The bolt is the 12-288: square corner faceplate, 1 x 2-1/4 inches, 1 inch housing diameter. Cross bore prep is 1-1/2 inches. Fixed 5 inch backset versions exist within the series for doors bored that way.
4) What door prep does a Schlage B581 one-sided deadbolt need?
A 1-1/2 inch cross bore through the door face, plus an edge bore for the 1 inch bolt housing. The faceplate is 1 x 2-1/4 inches with square corners and mortises into the door edge; drive-in bolt versions are available if you would rather skip the edge mortise. The jamb takes a 1-1/8 x 2-3/4 inch square corner strike, and the metal dust box reinforcer behind it anchors with three 3 inch screws. Outside trim is a 1 inch wrought brass or bronze ring with a security insert behind the blank plate.
5) What else can I use instead of a Schlage B581 if I need a non-keyed deadbolt with a blank plate on the outside?
The straight cross-brand equivalent is the Arrow E60, a Grade 2 non-keyed exit deadlock with the same blank plate and thumbturn arrangement. The functional difference is door range: the Arrow E60 is listed for 1-3/8 to 1-3/4 inch doors, while the thumbturn B500 covers 1-3/8 to 1-7/8 inches, so a door thicker than 1-3/4 rules the Arrow out. Another one-sided option is the Callan 205S, a Grade 3 one-sided deadbolt that preps as a half bore, so it is a different hole in the door, not a swap for a B581 already installed.
6) My door is 2 inches thick. Will a Schlage B581 work on it?
No. Thumbturn B500 deadbolts stop at 1-7/8 inches. For a thicker door, the Corbin Russwin DL3011 is a Grade 1 cylindrical deadlock listed for 1-3/4 to 2-1/4 inch doors, and the Deltana 7312KA2 covers 1-3/8 to 2 inches as a Grade 3 unit. Both of those are keyed rather than one-sided, so you gain the thickness but pick up a cylinder to key into your system.
7) Is there an equivalent to the Schlage B581 one sided deadbolt from another manufacturer?
The Arrow E60 exit deadlock is the direct functional counterpart. It is non-keyed and carries the same Blank Plate x Thumbturn function as the Schlage B581 - thumbturn on the inside face, plain plate on the outside - and both are ANSI/BHMA Grade 2. The Arrow E60 lists a door thickness range of 1-3/8 inch to 1-3/4 inch. The B581 covers 1-3/8 inch to 1-7/8 inch in the thumbturn-only configuration and its backset adjusts for 2-3/8 inch or 2-3/4 inch. On both, the bolt is thrown and retracted from the inside only, so the outside face has no key and no turn.
8) I need a key on the outside instead of a blank plate, and the building is already on Schlage keys - which deadbolt fits that?
The Schlage B581 is non-keyed, so the outside is a blank plate with no cylinder. Where the same opening needs outside key control on an existing Schlage key system, the Hager 3115 is a Grade 2 cylinder x thumbturn deadbolt supplied in the Schlage C keyway, with a listed door thickness range of 1-3/8 inch to 1-3/4 inch and a fire rating. The Hager 3118 is the Grade 1 classroom-function version, also Schlage C keyway with a 6-pin cylinder, same 1-3/8 inch to 1-3/4 inch door range. Both put a cylinder where the B581 puts a plate, so the outside prep changes from a blank rose to a cylinder hole.
9) Will the B581 deadbolt latch into the strike already in my jamb, and how do I keep a wood frame from getting kicked in?
The bolt throws 1 inch and the supplied strike is the 10-094, square corner, 1-1/8 x 2-3/4 inches, no box. If your jamb is mortised for that same square-corner cutout, it drops straight in; ANSI, round corner, and thimble strike versions are available when the existing prep has a different lip. On a wood frame the security comes from the metal dust box behind the strike, which anchors with three 3 inch screws into the framing behind the jamb rather than just the jamb itself, which is what resists a kick.
10) Is the Schlage B581 a commercial grade deadbolt, and what ANSI function number do I put on the hardware schedule?
Grade 2 under ANSI/BHMA A156.5, catalogued as medium duty commercial hardware. The function to write on a schedule is E01112: deadbolt operated by turn unit only, blank plate on the opposite side. Construction backs the grade up, a solid zinc bolt with a hardened steel anti-saw pin, a free spinning collar that resists wrenching, and a removable security shield that blocks an ice-pick attack through the door.
11) Can a Schlage B500 deadbolt go on a fire rated door?
Fire rated versions of the B500 Series are available as auxiliary locks, UL 10B and UL 10C listed, with UL 10C 3-hour rated options. A listed unit is identified by the letter F and the UL symbol stamped on the latch front, so you can check an installed bolt without pulling it. The fire rated bolts are ordered as an option and come with a fixed backset rather than the adjustable 2-3/8 or 2-3/4 inch bolt, so specify the fire rated version up front rather than assuming a standard B581 covers it.
12) I need a restroom or single-occupancy door bolt that shows whether it is in use. Does the B581 do that?
No. The B581 gives a plain blank plate on the outside, nothing to read. The occupancy indicator function in the same family is the B571, a door bolt with a thumbturn on one side and an occupancy indicator plate on the other, which is what belongs on a single-occupancy restroom or a changing room. The B580 is the third keyless option and has no exterior trim at all, for openings where the outside face is never seen or touched.
13) What if I want the same deadbolt but keyed from the outside?
Within the B500 Series the keyed functions are the B560 and B561 (single cylinder), the B562 (cylinder both sides), and the B563 classroom deadbolt, where the turn retracts only. Cross-brand, the Hager 3115 is a Grade 2 cylinder and thumbturn deadbolt on a Schlage C keyway for 1-3/8 to 1-3/4 inch doors, which matters if the building is already keyed Schlage C, and the Arrow DBX61 is another Grade 2 cylinder and thumbturn option. A B500 keyed unit takes conventional, FSIC, or SFIC cylinders, though SFIC drops the ANSI rating to Grade 3.
14) Will the B581 match the finishes on the rest of my building's hardware?
Eleven finishes are offered: 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, and 643E aged bronze. 626 satin chrome is the usual commercial match. B500 deadbolts suite with nearly all Schlage and Von Duprin product, so the exterior plate lines up with the locksets and exit devices already on the other openings, and LCN closers are covered in the same suiting.
15) Is the Schlage B581 thumbturn ADA compliant for an accessible opening?
The B500 thumbturn design is ADA compliant. Since the B581 is operated only from the inside turn, that turn is the whole operation, and there is no cylinder or outside knob to evaluate. For a healthcare or long-term-care facility, the 626AM satin chrome antimicrobial finish is one of the eleven finish options on the same part.
16) Does the Schlage B500 deadbolt meet Buy American Act requirements for a government job?
The B500 Series is Buy American Act compliant, which is what a federal, state, or public-school procurement package usually turns on. Pair that with the ANSI/BHMA A156.5 Grade 2 rating and the E01112 function code and you have the three things a spec reviewer asks for on a deadbolt line item.
17) I have a lot of these to do across a property. Is the B581 the same lock as a residential deadbolt from a home center?
Not the same prep. The B581 preps into a 1-1/2 inch cross bore, so measure the hole in an existing door before you order a stack of them, and it uses an adjustable 2-3/8 or 2-3/4 inch backset with a helix that locks the setting in place, so one part number covers both bores across a mixed building. Bolt housing is 1 inch, faceplate 1 x 2-1/4 inches square corner, strike 1-1/8 x 2-3/4 inches square corner. It is Grade 2 medium duty commercial rather than a residential unit, and it repeats across every opening in the same finish, which is what keeps a fleet of doors consistent.
18) What deadbolt takes a small format interchangeable core where the Schlage B581 has a blank outside?
The Arrow E61 in 26D is a Grade 2 single cylinder deadlock prepped for SFIC and shipped less core, so the facility installs its own core and keeps core control in house. Its listed door thickness range is 1-3/8 inch to 1-3/4 inch. The Schlage B581 is the non-keyed function, thumbturn inside and blank plate outside, so it holds no core at all; the B500 series accepts conventional, FSIC and SFIC formats on its keyed functions, and ANSI/BHMA Grade 2 certification on the series applies with a conventional or FSIC cylinder while SFIC is Grade 3.
19) Corbin Russwin lists a cylindrical deadlock as cylinder x blank - is that the same thing as a Schlage B581?
No, the operating side is opposite. The Corbin Russwin DL3011 and DL2211 are Grade 1 cylindrical deadlocks in a cylinder x blank arrangement, meaning a key cylinder operates the bolt and the other face is a blank plate with no operator. The Schlage B581 is the reverse: a thumbturn is the only operator, the outside is a blank rose, and there is no key anywhere on the lock. On a door where someone inside must throw the bolt by hand, the cylinder x blank deadlocks will not do it; on a door where the bolt must only be operated with a key, the B581 will not do it. The DL3011 lists a door thickness range of 1-3/4 inch to 2-1/4 inch and the DL2211 lists 1-3/4 inch.
20) What other one sided deadbolts are there besides the Schlage B581?
The Callan Model 205S is the other one sided pattern to look at - a Grade 3 one-sided half-bore deadbolt, so the body sits in a partial bore rather than a full through bore. The Schlage B581 is ANSI/BHMA Grade 2, rated medium duty, and takes a 1-1/2 inch cross bore prep with an adjustable 2-3/8 inch or 2-3/4 inch backset. The half-bore Callan changes the door machining; the B581 uses the same cross bore a standard tubular deadbolt uses, which matters when you are retrofitting a door already bored for one.
21) The door cannot take a cross bore - what deadbolt can I use instead of a Schlage B581?
The Schlage B581 needs a 1-1/2 inch cross bore prep through the door, with an adjustable 2-3/8 inch or 2-3/4 inch backset. Where that machining is not possible, the Codelocks CL200 is a surface mounted deadbolt with key override, rated light duty, which mounts to the face of the door instead of through it. The Codelocks CL2200 is the electronic surface mounted deadbolt in brushed steel, rated medium duty. Both change the look of the door face, since the lock body sits on the surface rather than flush in the bore.
22) My doors are thicker than 1-7/8 inch - what deadbolt do I order instead of a Schlage B581?
The Schlage B581 in its thumbturn-only form covers doors 1-3/8 inch to 1-7/8 inch thick. For a heavier leaf, the Corbin Russwin DL3011 Grade 1 cylindrical deadlock lists a door thickness range of 1-3/4 inch to 2-1/4 inch, and the Deltana 7312KA2 lists 1-3/8 inch to 2 inch as a Grade 3 double cylinder. Both are keyed rather than turn operated - the DL3011 is cylinder x blank and the 7312KA2 takes a key on both faces - so the operator on the door changes along with the thickness coverage.
23) The spec calls for a Grade 1 deadbolt - what should I quote instead of the Schlage B581?
The Schlage B581 is ANSI/BHMA Grade 2 and rated medium duty. Where a drawing calls out Grade 1, the Falcon D111 is a Grade 1 classroom deadbolt rated heavy duty with an adjustable backset, the Dexter DB1000 single cylinder is Grade 1 with a door thickness range of 1-3/8 inch to 1-7/8 inch, and the Design Hardware D1 is a Grade 1 double cylinder rated extra heavy duty for 1-3/4 inch doors. All three are keyed cylinder functions rather than the non-keyed thumbturn arrangement of the B581, so confirm the drawing wants a key on the door before substituting. If the spec allows Grade 2, the Falcon D211 is the medium duty Grade 2 cylinder x thumbturn in the same tier as the B581.
24) Can one deadbolt cover both 2-3/8 inch and 2-3/4 inch backset doors across a property?
The Schlage B581 has an adjustable backset for 2-3/8 inch or 2-3/4 inch, with a lock-in-place helix design, so one part number sits on both bore layouts and there is no need to sort stock by backset. Among other brands, the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset and the Brinks E2401 offers a 4-way adjustable backset. Fixed backset alternatives commit you to one dimension: the Accentra D111 is a Grade 1 single cylinder deadbolt built at 2-3/8 inch backset, and the Deltana CL200LA is a Grade 2 single deadbolt at 2-3/4 inch backset.
25) Which parts look like a deadbolt in a search but will not replace a Schlage B581?
Three items sit close to the same search terms and are not complete locks. The BEST 8T is the tubular deadbolt tube component of the T Series, that is the bolt body alone rather than a finished lock with trim. The Baldwin Reserve 8BR0618001 is a deadbolt spacer for a double cylinder application, a fitting used behind trim. The Arrow 460 is a mortise lock strike for latchbolt and deadbolt functions with a straight lip, so it is frame hardware, not door hardware. The Schlage B581 ships as a complete one sided deadbolt with the thumbturn, the outside blank rose trim, a 1 inch by 2-1/4 inch square corner faceplate and a 1-1/8 inch by 2-3/4 inch square corner strike.
26) I want the same inside-only operation but with a credential on the outside - what replaces a Schlage B581?
The Schlage B581 is a mechanical, non-electronic lock: a thumbturn throws the bolt and the outside face is a blank plate with nothing to present a credential to. If the outside needs to open on a card or a code, the Codelocks CL2200 is an electronic surface mounted deadbolt rated medium duty, the Codelocks CL2210 is the electronic mortise deadbolt version, and the Dormakaba Nova-D is an RFID multihousing smart electronic deadbolt. All three add power and credential management that the mechanical B581 does not carry, and the door prep differs from the 1-1/2 inch cross bore the B581 uses.
27) The door needs a latch as well as a deadbolt - is the Schlage B581 the wrong choice?
The Schlage B581 is a deadbolt only, thumbturn inside and blank plate outside, so it holds the door locked but does nothing to keep it latched closed; it is used alongside a separate knob, lever or exit device. Where one device should handle both, the Falcon H2101 is a Grade 2 entrance interconnected lock that combines the latch with a single cylinder deadbolt in one assembly. The interconnected unit needs its own door prep, so it is a planned change rather than a drop-in for a door already bored for the B581.
28) Which deadbolts have an ADA friendly turn piece if the Schlage B581 does not suit the opening?
The Schlage B581 uses an ADA compliant thumbturn design, and the turn is the only operator on the lock. Where a different brand is needed, the Cal-Royal LSD is a Grade 3 single cylinder deadbolt built with an ADA ergonomic thumbturn, listed for doors 1-3/8 inch to 1-3/4 inch thick. The Cal-Royal LSD adds a key cylinder on the outside face, where the B581 carries a blank rose, so the outside prep is not the same.
29) What if the opening needs a key on both sides rather than a thumbturn?
The Schlage B581 puts a thumbturn on the inside and a blank plate outside, with no cylinder on either face. For a door that must be keyed from both sides, the Hager 3214 is a Grade 2 double cylinder deadbolt in the Schlage C keyway, listed for doors 1-3/8 inch to 1-3/4 inch with a fire rating. The Delaney LU Series 320601 is a Grade 2 double cylinder deadbolt in stainless steel US32D, and the Callan Model 210S is the Grade 3 double cylinder. A double cylinder removes the inside turn piece, so check the egress requirements for the door before switching from the B581 arrangement.
30) What is the Schlage B581 door bolt used for?
The Schlage B581 is a Grade 2 deadbolt with trim designed for commercial and residential security applications. It provides single-cylinder deadbolt locking with a keyed exterior and thumb turn interior. Common uses include office doors, apartment entries, and heavy-duty residential applications.
31) How do I determine the correct handing for this deadbolt?
The B581 is typically non-handed and can be field-reversed during installation. The cylinder can be installed on either side of the door. Check the installation instructions to confirm proper orientation of the thumb turn and ensure the bolt projects into the door frame correctly.
32) Can this deadbolt be keyed to match existing Schlage locks?
Yes, the B581 uses standard Schlage C keyway and can be keyed alike or integrated into master key systems. Consult with a locksmith or key system provider to match existing keys or create a master key arrangement. Different keyways may be available for specific applications.
33) How do I maintain and adjust the B581 deadbolt?
Regular maintenance includes periodic lubrication of the cylinder and bolt mechanism with dry graphite lubricant. Avoid oil-based lubricants that attract dirt. Check strike plate alignment if the bolt becomes hard to operate. Ensure the door frame remains square and the strike plate stays properly aligned.
34) What door and frame conditions work best with this deadbolt?
The B581 works best with solid wood or metal doors in square, properly hung frames. Ensure adequate door stile width for proper installation. Hollow core doors may require reinforcement. The door frame must be sturdy enough to resist force applied to the deadbolt when locked.
