Sargent 28-2494 Non-Rated Top Latch | For 3727 Exit Devices

The Sargent 28-2494 is a genuine OEM replacement top latch assembly specifically engineered for Sargent 3727 Surface Vertical Rod (SVR) Exit Devices. Designed for use on non-fire rated doors, this kit includes the complete internal latching mechanism and a protective EN (Aluminum) finish cover. This assembly ensures the door remains securely latched at the header, providing essential perimeter security and reliable mechanical operation.

Professional-Grade Features & Benefits

• Direct 3727 Series Compatibility: Precision-calibrated to interface perfectly with the vertical rods and lift-members of the Sargent 3700 series architecture.
• Non-Rated Optimization: Engineered specifically for "Panic Hardware" applications where a fire-life safety rating (12-prefix) is not required.
• Architectural EN Cover Included: Comes with a factory-finished aluminum cover to protect the latch mechanism from dust, debris, and tampering.
  
• Positive Latching Engagement: Features a heavy-duty internal spring and trip-lever system that ensures the latch clears the strike during opening and deadlocks securely when closed.
• OEM Precision Fit: Replacing a worn top latch with a genuine Sargent 28-2494 restores factory-spec performance without the need for field modifications.

The Sargent 28-2494 is a vital repair part for SVR devices in high-traffic commercial environments. Because the top latch handles the primary deadlocking function, a worn internal lever can cause the door to "bounce" open or fail to latch entirely. If your door isn't staying closed at the top, replacing the entire 28-2494 assembly is often more effective than attempting to repair individual internal springs.

Installation Note: For the top latch to engage the strike consistently, the exit device chassis must be rock-solid. We highly recommend anchoring the 3727 device using high-strength thru bolts. A stable, thru-bolted connection prevents the device from sagging over time, which keeps the vertical rods in perfect alignment and prevents the 28-2494 latch from binding against the header.
