Key takeaways
- The B600 Series is Schlage's Grade 1 commercial deadbolt and the B500 Series is its Grade 2 deadbolt. The B250 in the same catalog is a deadlatch, not a deadbolt.
- Some interchangeable cores lower the listed grade. Schlage lists the B600 at Grade 2 with full size interchangeable cores (FSIC) and Grade 3 with small format interchangeable cores (SFIC), and the B500 at Grade 3 with SFIC cores.
- The function is what you see on each side of the door. A classroom deadbolt looks like a single cylinder deadbolt, but its inside thumbturn (a small knob turned by hand) can only retract the bolt.
- Both series list a 1-inch throw and a backset (the distance from the door edge to the center of the lock) adjustable to 2-3/8 or 2-3/4 inches.
Identify
Which Schlage deadbolt do I have?
Schlage's B Series catalog covers Grade 1 and Grade 2 deadbolts, plus the Grade 2 B250 deadlatch. The Grade 1 deadbolt is the B600 Series and the Grade 2 deadbolt is the B500 Series. The series sets the grade; the function, covered next, is what you see on each side of the door.
Locks previously known as the B700 and B800 Series are now versions of the B600 Series. The faceplate, the plate on the door edge the bolt slides out through, differs in size between the two series, as the table shows.
Both cut sheets say: "Letter F and UL symbol on latch front indicate listing."
Trim showing LOCKED or UNLOCKED, or OCCUPIED or VACANT, is the optional lock status indicator trim the B600 cut sheet describes, on one side of the door or both. The message shows on a white background when unlocked and on a red background when locked.
For how deadbolt grades, functions and egress rules work on any brand, see the general commercial deadbolt guide.
| Line | What it is | Grade as Schlage lists it | Standard faceplate |
|---|---|---|---|
| B600 Series | Grade 1 deadbolt; includes locks previously known as B700 and B800 Series | ANSI/BHMA A156.36-2020, Grade 1 auxiliary lock | 1-1/8" x 2-1/4", square corner |
| B500 Series | Grade 2 deadbolt for light- to medium-duty commercial and residential settings | ANSI A156.36-2020, Grade 2 auxiliary lock (except B581) | 1" x 2-1/4", square corner (U.S. default); 1-1/8" x 2-1/4" Canadian default |

Functions
What does each function do?
The function is what is on each side of the door, and it decides who can lock and unlock it. A single cylinder and a classroom deadbolt both have a key cylinder outside and a thumbturn (a small knob turned by hand) inside; on the classroom function the thumbturn can only retract (pull back) the bolt.
In the table, thrown means the bolt is pushed out to lock and retracted means it is pulled back to unlock.
In Schlage's product identification guide, a number such as B560F reads as the lock series, then the function code, then F for the fire rated option. That option is standard on B600 functions.
One more B500 number, the B571 door bolt occupancy indicator, is listed as discontinued in Schlage's B-Series service manual.
The commercial lock functions guide explains how lock functions behave from each side of the door.
| Function | B600 Series | B500 Series | How Schlage describes it |
|---|---|---|---|
| Single cylinder deadbolt | B660, ANSI E0151 | B560/B560F, ANSI E0152 | Key cylinder outside; thumbturn inside. Deadbolt thrown or retracted by key outside or thumbturn inside. |

Grades
What grade is it, and what cylinder does it take?
Schlage lists both series under A156.36-2020, the ANSI/BHMA standard for auxiliary locks such as deadbolts, and lists a lower grade for some interchangeable core formats. An interchangeable core is a cylinder core that can be removed and replaced with another.
The cylinder is the keyed part of the lock, and the keyway, in the table, is the shape of its key slot.
Schlage's specifications list the B600 and B500 as "UL 437 listed when using Primus high-security UL 437 cylinder." UL 437 is UL's standard for high-security key locks, and Primus is Schlage's high-security cylinder.
The rekey, master key, SFIC and LFIC guide covers interchangeable cores and keying systems.
| Item | B600 Series Grade 1 | B500 Series Grade 2 |
|---|---|---|
| Grade | ANSI/BHMA A156.36-2020, Grade 1 auxiliary lock | ANSI A156.36-2020, Grade 2 auxiliary lock (except B581) |
| Grade with interchangeable cores | FSIC: Grade 2. SFIC: Grade 3. | SFIC: Grade 3. |
| Bolt material | Sintered steel | Solid zinc |

Fire and egress
What matters on a fire-rated or exit door?
UL 10C is UL's positive pressure fire test for door assemblies, and CAN/ULC-S104 is the Canadian fire test for door assemblies.
The B600 cut sheet reads "UL 10C and CAN/ULC-S104 listed" and "3-hour fire rated as auxiliary locks", and adds "UL 10B listed for neutral pressure doors".
The B500 cut sheet reads "Available deadbolt option is UL 10C and CAN/ULC-S104 listed (except B562)" and "3-hour fire rated as auxiliary locks". It is ordered by adding F to the function.
The catalog says a "fire cup" is standard on all B600 Series deadbolts, and for the B500: "Locks ordered with optional fire rating will include a fire cup."
Schlage prints this caution on the B662 and B562 double cylinder functions: "Double cylinder locks on any door, in any structure which is used for egress are a life safety hazard in times of emergency and their use is not recommended. Installation should be in accordance with existing codes only."
The California egress requirements guide and the fire-rated door requirements guide cover the opening itself.

Door fit
Will it fit my door?
Schlage lists a 1-inch throw for both series (the throw is how far the bolt extends from the door edge), and a backset (the distance from the door edge to the center of the lock) adjustable to 2-3/8 or 2-3/4 inches. The door thickness each one fits depends on the cylinder format.
Doors 1-3/8 inches thick cannot use interchangeable cores. For thick doors, the comparison table lists thick door kits to 4 inches for the B600.
For the B500, the table gives door thickness from both the cut sheet and the B500 door template index, which lists it function by function.
| Item | B600 Series | B500 Series |
|---|---|---|
| Throw | 1" | 1" |
| Bolt | Solid, sintered steel, .81" x .62", with concealed hardened steel anti-saw pin insert | Solid zinc, 0.81" x 0.62", with concealed hardened steel anti-saw pin insert |
| Housing diameter | 1" | 1" |
| Backset | Standard: adjustable 2-3/8" or 2-3/4". Fixed backset options available. | Adjustable for 2-3/8" or 2-3/4" |

Door prep
Bore, bolts and templates, for the installer
The bore is the hole drilled through the face of the door for the lock. The B600 cylinder only deadbolt and the door bolts with no outside trim on both series are 1-1/2-inch bore only. Indicator options are only compatible with a 2-1/8-inch bore.
The anti-pry shield on both series is removable for 1.5-inch cross bore installations; for the B500, the comparison table notes that this alters exterior appearance.
A rabbeted door and frame, in the table's strike kit row, have a stepped edge where they meet.

Strike
What goes on the frame?
The strike is the plate on the door frame that the bolt goes into. The default strike on both series is square corner, 1-1/8 by 2-3/4 inches, part 10-094. Both cut sheets say its metal dust box, the box behind the strike that encloses the bolt hole, is anchored to the frame with three 3-inch screws.
All B Series strikes are fully reversible for right-handed and left-handed doors and are furnished complete with screws.
The wood door frame reinforcer, 37-016 in the table, is concealed under the strike and anchored to the jamb with two 3-inch long screws.
Schlage's documents place the reinforcer differently. The catalog's comparison table lists it as a B600 option, and the B600 cut sheet says an optional strike reinforcer is available; the catalog's strike table marks the reinforcer, the 10-108 strike and the 10-112 dust box for the B500 only.
The commercial strike plates guide covers strike types and how a strike sits in the frame.

Mortise
Schlage L Series mortise deadbolts
Schlage also makes mortise deadbolts, where the lock body sits in a pocket cut into the edge of the door. Both lines here are deadbolt-only locks with no lever handle (Schlage calls them leverless).
The L Series Grade 1 mortise deadbolt comes in 4 functions, based on an L Series mortise chassis. Its product page reads: "Tested and certified to ANSI/BHMA Grade 1 operational and security standards".
The L400 small case mortise deadbolt is Grade 1, made to fit a small cutout and offered in 6 functions. It has a 1-inch (25 mm) stainless steel throw deadbolt, and the small case is not available with escutcheon trim (a plate-style trim). Its uses include doors where latching is not required and doors to utility spaces.
The commercial mortise lock guide covers mortise lock bodies and door prep.
