Sargent 05-2182 Guarded Latchbolt – 2-3/4" Backset for 6500 Series Locks

The Sargent 05-2182 is an OEM replacement guarded latchbolt engineered for Sargent 6500 Series cylindrical locksets. Designed with a 2-3/4" backset — the standard commercial backset dimension — this latchbolt is the correct service part for locking-function variants including models 65G04, 65G05, 65G37, and 65G15-3. Sourcing the right replacement latchbolt keeps existing hardware in service without a full lockset changeout, reducing downtime and replacement cost for facility managers and service technicians alike.

What Is a Guarded Latchbolt?

A guarded latchbolt (also called a deadlocking latchbolt or auxiliary deadlatch) includes a secondary plunger or guard tab positioned alongside the primary spring latch. When the door is closed and the latchbolt engages the strike, the guard is depressed by the strike lip, preventing the primary latch from being retracted by shimming, carding, or lateral pressure. This feature is essential on locking-function cylindrical locks where the latchbolt must resist forced entry attempts — a requirement on commercial security and access-controlled openings. For fire-rated openings, positive latching provided by the latchbolt is also a code requirement.
