About this item

 

The Schlage B663 is the classroom function in the Schlage B600 Series Grade 1 commercial deadbolt line. ANSI Function E0171. The deadbolt is thrown only by a key from the exterior. The deadbolt is retracted by key from the exterior or by thumbturn from the interior. The inside thumbturn can retract the bolt but cannot project it. This is the defining behavior of the classroom deadbolt function and it is distinct from a standard single-cylinder deadbolt. American Locksets is an authorized Allegion Schlage dealer stocking the B663 with same-day shipping and free shipping on orders over $300.

 

Schlage B663 Classroom Deadbolt: Why the Function Matters

 

The classroom deadbolt function, ANSI E0171, is specifically designed for K-12, higher education, and institutional doors where lockdown security requirements call for keyed exterior deadbolt control combined with interior thumbturn egress. The critical distinction is that the thumbturn inside can only retract the bolt. It cannot project (throw) the deadbolt. Throwing the deadbolt requires a key from the exterior.

 

This prevents an occupant inside from deadbolting themselves without authorized key control, which is a requirement in many school security protocols. The teacher or authorized personnel hold the key and control whether the deadbolt is thrown. The thumbturn allows the occupant inside to retract the bolt and exit at any time. On a school lockdown, the deadbolt is thrown by a key from the outside, which cannot be undone from inside without a key.

 

This is different from the standard B660 single-cylinder deadbolt, where the thumbturn operates the bolt fully in both directions from inside.
