Sargent 05-2185 Latchbolt — 2-3/8" Backset, Unguarded, US26D Satin Chrome Finish

The Sargent 05-2185 is a factory replacement latchbolt designed for Sargent 6500 Series cylindrical locksets. Finished in US26D (Satin Chrome), this unguarded latchbolt is the correct service part for 65U15 and 65U65 function locks, providing a precise, OEM-matched fit that restores proper latching performance without the cost or complexity of a full lock replacement.

With a 2-3/8" backset, this latchbolt suits the most common commercial door prep — standard in office, institutional, healthcare, and education applications. Sourcing the correct Sargent replacement latchbolt by part number ensures dimensional accuracy, proper spring tension, and compatibility with the existing strike and door prep.

What Is an Unguarded Latchbolt?

An unguarded latchbolt does not include a deadlatch plunger (auxiliary latch). It relies solely on the spring-loaded bevel bolt to hold the door in the closed position. Unguarded latchbolts are specified for the 65U15 and 65U65 functions where the lock design or application does not require the added security of a guarded (deadlatching) configuration. Verify your existing Sargent 6500 Series function before ordering to confirm unguarded is correct for your application.
