Sargent 82-0161 Spring | For 8200 Series Classroom Function Locks

The Sargent 82-0161 is a genuine OEM Internal Replacement Spring designed specifically for Sargent 8200 Series Mortise Locks configured with the Classroom Function (e.g., 8237). This spring provides the tension required for the specialized locking logic that allows the outside lever to be locked or unlocked by a key, while always permitting free egress from the inside. Identified as Part #6 on official technical diagrams, this is a critical component for school safety and institutional security.

Institutional Grade Features & Benefits

• Function-Specific Engineering: Tailored precisely for the mechanical requirements of classroom and security-classroom functions.
• Premium Spring Steel: Manufactured from high-tensile, tempered spring steel to maintain constant pressure over millions of key cycles.
• Direct OEM Fit: As Part #6, it is guaranteed to align perfectly within the 8200 series cassette, ensuring the locking piece shifts smoothly between the locked and unlocked states.
• Restores Life-Safety Compliance: Essential for ensuring that the outside lever correctly resets, preventing unauthorized entry while maintaining a "fail-safe" exit path.
• Cost-Effective Repair: Replacing a fatigued or snapped spring (Part #6) restores the "factory feel" of the lock for a fraction of the cost of a new mortise body.
