Sargent 82-0368 Mortise Lock Spindle | For 7800 & 8200 Series

The Sargent 82-0368 is a genuine OEM replacement spindle designed for the industry-leading Sargent 8200 and 7800 Series Mortise Locks. As the central drive component of the lockset, this spindle transfers the rotational force from your lever handles directly to the internal lock hubs. Specifically sized for 1-3/4" thick doors, the 82-0368 ensures a perfect, "slop-free" fit that is critical for the smooth operation of high-traffic commercial and institutional doors.

Precision Engineering & Performance Features

• Direct 8200/7800 Series Compatibility: Engineered to meet the exact factory tolerances of Sargent's premium mortise lock lines, ensuring seamless integration with original hardware.
• Optimized for 1-3/4" Doors: Precision-cut to the industry-standard door thickness, providing full engagement with both the interior and exterior trim without binding.
  
• Heavy-Duty Torque Resistance: Manufactured from high-strength steel to withstand the daily mechanical stress of high-frequency use in schools, hospitals, and office buildings.
• Smooth Operation: Eliminates the "loose" or "slipping" handle feel often caused by worn or rounded-off aftermarket spindles.
• Architectural Quality: Designed to maintain the precise timing required for Sargent’s "Apex" and legacy mortise mechanisms.

The Sargent 82-0368 is the first part you should check if your lever handle turns but the latch fails to retract. Over decades of service, spindles can experience metal fatigue or shearing. Because Sargent 8200 series trim is secured using high-strength thru bolts, ensuring your spindle is centered during installation is vital. If the spindle is off-center, it may not provide enough "bite" on one side, leading to a handle that spins freely.

Installation Note: We recommend applying a light coating of lithium grease to the ends of the spindle before inserting it into the lock body hubs. This reduces friction and prevents the "clicking" sound often heard in older mortise lock assemblies.
