Schlage B250 Single Cylinder Deadbolt — Grade 2 Deadlatch
The Schlage B250 is an ANSI/BHMA A156.36 Grade 2 single-cylinder deadlatch engineered for commercial and institutional applications where self-locking re-engagement is required. Unlike a standard deadbolt, the B250's spring-loaded latchbolt automatically deadlocks on door closure — eliminating the need to manually throw the bolt. The inside thumbturn includes a holdback feature that keeps the latch retracted for nightlatch use. Available in two cylinder formats (conventional 6-pin C keyway and Full-Size Interchangeable Core) and seven finishes, the B250 suits everything from apartment entry doors to pool gates and perimeter openings.
Features & Benefits
Strength and Security
- 5/8" throw deadlatch resists prying attacks and shimming of the latch
- Concealed frame reinforcer protects wood jamb against kick-in attacks
- Free-spinning, tapered cylinder collar with security insert resists wrenching and prying
- Thumbturn holdback feature retains the deadlatch in a retracted position when desired
- UL 437 listed option available — resists drilling and physical attack on the cylinder
Key System Security
- Open and restricted keyway options
- Primus XP program geographic exclusivity available
- Factory master keying available
- Two cylinder formats: Conventional 6-pin C keyway (P6/PD suffix) and Full-Size Interchangeable Core less core (J suffix) — FSIC format is ideal for institutions managing large key systems where cores are swapped rather than rekeyed
