Sargent 82-5634 Thumbturn Plate Only – Genuine OEM Replacement for 8200 & 7800 Series Mortise Locks
The Sargent 82-5634 Thumbturn Plate Only (also referenced as SA194 / SA196) is a genuine OEM replacement thumbturn component designed specifically for Sargent 8200 Series and 7800 Series mortise locks. When an original thumbturn plate shows wear, damage, or loss of function, this factory-authorized part restores proper interior deadbolt or latch control without the cost or complexity of replacing the entire mortise lock assembly. Specifying a genuine Sargent replacement ensures dimensional accuracy, correct fit, and reliable long-term performance in commercial and institutional door hardware applications.
Institutional Grade Features & Benefits
- Genuine OEM Component: Factory-authorized Sargent replacement part — not an aftermarket substitute — ensuring precise fit and finish within the 8200 Series mortise lock body.
- Direct Drop-In Replacement: Engineered to exact Sargent tolerances for the 8200 and 7800 Series mortise lock platforms, minimizing installation time and eliminating the need for field modifications.
- Restores Interior Control: Returns the thumbturn mechanism to proper operating condition, allowing reliable manual actuation of the mortise lock from the interior side of the door.
- Commercial & Institutional Grade: Built to withstand the high-cycle demands of office buildings, healthcare facilities, educational institutions, government facilities, and multi-family residential applications.
- Reduces Total Replacement Cost: Replacing only the worn or damaged thumbturn plate component — rather than the complete mortise lock — significantly lowers material and labor costs.
- Maintains Hardware Consistency: Preserves the appearance and operational integrity of an existing Sargent mortise lock installation, important for facilities with standardized hardware specifications.
