Sargent 82-5263 Latchbolt Assembly | for 7800 & 8200 Series

The Sargent 82-5263 is a genuine OEM replacement latchbolt assembly designed for the industry-leading Sargent 8200 and 7800 Series Mortise Locks. As the primary point of contact between the door and the strike plate, the latchbolt is subject to constant friction and impact. Replacing a worn or damaged latchbolt with this factory-spec assembly restores the reliable, "snap-back" action required for high-traffic commercial entrances, stairwells, and office suites.

Precision Engineering & Maintenance Features

• Direct Mechanical Replacement: Specifically engineered to fit the internal chassis of Sargent 7800 and 8200 series locks, ensuring perfect alignment with the hub and spring mechanisms.
• Component Accuracy: Identified as Item #2 on the standard Sargent mortise case exploded diagram, making it the correct choice for targeted internal repairs.
  
• High-Durability Construction: Forged from premium materials to resist the shearing forces and friction of daily commercial use.
• Anti-Friction Design: Designed to work seamlessly with Sargent strike plates to provide a smooth closing cycle and prevent door "bounce-back."
  
• Cost-Effective Restoration: Allows facility managers to repair high-value mortise cases rather than replacing the entire lock body.

Critical Maintenance Note:

The Sargent 82-5263 is intended for use in mortise locks that are outside of their original 10-year factory warranty. Please be advised that opening the mortise lock case will void any remaining manufacturer warranty. This part is recommended for experienced locksmiths and maintenance professionals comfortable with internal mortise lock timing and spring tension.

*** Latchbolt is #2 labeled in diagram above ***

A failing latchbolt is often the cause of a door that "drags" or requires extra force to close. When installing the 82-5263, ensure the internal case springs are properly seated and that the case is re-secured using the original armored front screws. Because these high-security locks are often mounted with thru bolts, verify that the door handles are properly aligned after the case is reinstalled to prevent unnecessary side-pressure on the new latchbolt.

Installation Note: We recommend applying a small amount of high-quality synthetic lubricant to the tail of the latchbolt during installation to ensure the smoothest possible operation within the case slides.
