Sargent 98-2559 Mullion Top Retainer Pack - Fire-Rated

The Sargent 98-2559 is a genuine OEM Mullion Top Retainer Pack specifically designed for use with Sargent 12-L980 and 12-980 Series fire-rated removable mullions. This heavy-duty hardware pack includes the top bracket (retainer) that mounts directly to the door frame header, providing the secure "pocket" where the mullion latch bolt engages. As a factory-certified fire-rated component, the 98-2559 is essential for maintaining the structural integrity of double-door openings that utilize rim exit devices.

Institutional Grade Features

• Fire-Rated Compliance: Specifically engineered for 12- prefix mullions, ensuring the opening meets NFPA 80 fire-safety standards for self-latching double doors.
• Grade 1 Structural Foundation: Manufactured from high-strength cast iron or steel to resist the extreme torque and pressure exerted on the mullion during high-traffic use or emergency egress.
• Precision Fit: Designed to interface perfectly with the 98-2520 Latchbolt Assembly [link], providing a snap-tight fit that eliminates mullion rattling and "play."
• Direct OEM Replacement: The correct hardware set for replacing damaged, bent, or worn-out top retainers in schools, hospitals, and commercial buildings.
• Corrosion Resistant Finish: Built to withstand the environmental stresses of main entrance vestibules and exterior-facing fire exits.
