Sargent 68-4558 Fire Rated Bottom Latch Assembly - 12-8700 Series

The Sargent 68-4558 is a genuine OEM Fire Rated Bottom Latch Assembly specifically engineered for Sargent 12-8700 Series Surface Vertical Rod (SVR) exit devices. This heavy-duty assembly serves as the lower locking point for fire-labeled openings, ensuring the door remains deadlocked to the floor or strike under extreme conditions. Designed for devices manufactured after November 11, 2002, this factory-spec component is essential for maintaining both life-safety compliance and the structural integrity of your fire-rated door assemblies.

Institutional Grade Features & Benefits
