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
- UL Fire Rated Construction: Built to the stringent specifications of the "12-" prefix series, ensuring the device maintains its fire label and positive latching requirements.
- Post-2002 Engineering: Features the updated internal architecture designed to interface perfectly with 8700 series SVR devices manufactured after 11/11/2002.
- Precision Bolt Retraction: Engineered to provide a crisp, full retraction of the bottom bolt to prevent dragging, which is the leading cause of threshold damage.
