Yale D162 Classroom Function Deadbolt - 2-3/4" Backset (US26D)
- Key outside operates deadbolt
- Thumb turn inside retracts deadbolt, but doesn't throw deadbolt
The Yale D162 is a heavy-duty, ANSI/BHMA Grade 1 certified deadbolt specifically engineered for commercial and institutional environments where controlled egress and maximum security are paramount. This Classroom Function deadbolt provides a specialized security layer: the exterior key operates the deadbolt for both locking and unlocking, while the interior thumbturn can only retract the bolt—never throw it. This prevents unauthorized individuals from locking the door from the inside, a critical safety feature for schools and public offices.
Built to withstand the rigors of high-traffic use, the D162 features a solid steel deadbolt with a hardened, free-spinning steel pin insert to resist sawing and tampering. Its 626/US26D Satin Chrome finish offers a professional, corrosion-resistant aesthetic that matches standard commercial hardware.
Key Performance Features
- Classroom Security Function: Ensures the room cannot be locked from the inside via the thumbturn, maintaining administrative control over the opening.
- Grade 1 Strength: Certified to ANSI/BHMA A156.36 Grade 1 standards, the highest rating for auxiliary locks, ensuring millions of reliable cycles.
- Fire-Rated Protection: UL/cUL listed for use on fire doors rated up to 3 hours (steel) and 1-1/2 hours (wood composite).
- Tamper Resistant: Equipped with a 1" throw solid steel bolt and a hardened steel pin to thwart forced entry attempts.
