PDQ KT148 Heavy Duty Classroom Deadlock

Function Information:

• Lock or unlock by key from outside
• Turnpiece inside retracts deadbolt, but will not project it
• ANSI E1171

The PDQ KT148 is an institutional-grade Classroom Function Deadlock designed specifically for educational facilities, public buildings, and commercial spaces where life safety and controlled access are paramount. Engineered to provide a secondary layer of high-strength security, this heavy-duty deadbolt solves the unique challenge of securing a room from the outside while ensuring that occupants can always exit quickly in an emergency.

Constructed with a reinforced zinc diecast rose and a solid brass bolt, the KT Series is built to withstand the physical demands of high-traffic environments. Its US26D Satin Chrome finish provides a professional, architectural look that is both corrosion-resistant and durable.

ANSI E1171 Function Summary: Life-Safety Classroom Security

The ANSI E1171 (Classroom) function is a specialized security configuration designed to prevent unauthorized locking of a door from the inside while maintaining a clear path for egress.

• Exterior Operation: The deadbolt is projected (locked) or retracted (unlocked) only by a key from the outside.
• Interior Operation: The interior turnpiece can only retract the deadbolt; it cannot be used to project the bolt to lock the door.
• Security & Safety Logic: This prevents students or unauthorized individuals from locking a teacher or official out of a room. Simultaneously, it ensures that if the door is locked from the outside, an occupant inside can always turn the thumbturn to retract the bolt and exit immediately without needing a key.

Technical Specifications

High-Security Solutions for Modern Facilities

The PDQ KT Series deadbolt is precision-engineered to address the specific vulnerabilities of commercial and institutional door openings:

• Anti-Saw Protection: The 1" throw brass bolt contains two concealed 1/4" case-hardened steel roll pins. These pins spin freely if an intruder attempts to saw through the deadbolt, effectively neutralizing the attack and keeping the door secure.
• Vandal-Resistant Housing: Featuring a reinforced zinc diecast rose and wrought brass scalp, the KT148 provides a high-strength anchor for the cylinder, protecting the internal mechanism against prying or wrenching.
• Flexible Installation: Designed to fit standard 161 door preparations (1-7/8" or 2-1/8" bores), making it an ideal "drop-in" solution for facility-wide security upgrades and retrofits.
• Seamless System Integration: While supplied with the industry-standard Schlage C (SCC) keyway, the KT Series can be keyed into most major manufacturers' systems, allowing you to maintain a single-key protocol across your entire property.
• Government & Municipal Compliance: Assembled in the USA, this hardware meets the strict domestic sourcing requirements for federal, state, and municipal contracts.
