Sargent 28-2493 Fire Rated Top Latch | For 12-3727 Devices

The Sargent 28-2493 is a genuine OEM replacement Fire Rated Top Latch Assembly specifically engineered for Sargent 12-3727 Surface Vertical Rod (SVR) Exit Devices. Designed for use on UL Fire Rated doors, this assembly includes the high-strength internal latching mechanism and a protective EN (Aluminum) finish cover. This unit ensures the door remains securely deadlocked at the header during a fire event, preventing door warping and maintaining the smoke seal.

The Sargent 28-2493 is the most critical repair part for fire-rated SVR devices. Because the top latch handles the "deadlocking" function, a worn or dirty internal trip-lever can cause the door to bounce off the strike or fail to latch entirely. On a fire-rated opening, this is a major compliance violation. Replacing the entire 28-2493 assembly ensures your fire door remains a reliable barrier during an emergency.

Installation Note: For the top latch to engage the header strike consistently, the exit device must be perfectly anchored. We highly recommend securing the 12-3727 chassis using high-strength thru bolts. A stable, thru-bolted connection prevents the device from sagging, which keeps the vertical rods in perfect alignment and prevents the 28-2493 latch from binding or "hanging up" on the strike plate.
