Sargent 05-2183 Latchbolt — 2-3/4" Backset, Unguarded, for 6500 Series (65U15 / 65U65 Functions)

The Sargent 05-2183 is an OEM replacement latchbolt designed specifically for the Sargent 6500 Series cylindrical lockset. Engineered as an unguarded latchbolt with a 2-3/4" backset, this component is the correct service part for doors prepped to the standard commercial cylindrical lock backset dimension — keeping your 6500 Series hardware operational without a full lockset replacement.

What "Unguarded" Latchbolt Means

An unguarded latchbolt does not include an auxiliary deadlatch plunger. This makes it the appropriate replacement for passage (65U15) and privacy (65U65) functions — applications where the door does not require deadlatch security protection. Passage function allows free movement through the door from either side; privacy function allows the occupant to prevent entry from the outside using a turn button, with emergency release capability. Neither function requires the anti-shimming protection that a guarded (deadlatching) bolt provides.

Compatible Functions

• 65U15 — Passage Function: Lever or knob retracts the latch from either side at all times. No locking capability. Commonly used in corridors, storage rooms, and interior openings where free passage is required.
• 65U65 — Privacy Function: Outside lever retracts latch freely except when locked by an inside turn button. Inside lever always retracts. Includes emergency release. Typical applications: single-occupancy restrooms, dressing rooms, private offices.

Key Benefits

• Direct OEM fit for Sargent 6500 Series cylindrical locksets — no modification required
• 2-3/4" backset matches the standard commercial door prep per ANSI 115.2 (the canonical commercial latch location)
• Restores proper door latching function — a positively latched door resists wind pressure and casual contact
• Cost-effective component-level repair — replace only what is worn or damaged
• Unguarded design correctly matched to passage and privacy function hardware

Typical Applications

• Commercial office interiors — corridor and private office doors
• Healthcare and institutional facilities — non-secure interior passages
• Schools and educational facilities — passage and restroom doors
• Hospitality and multi-family — privacy and passage applications
• Replacement / maintenance service on existing 6500 Series installations
