Sargent 98-0018 Outside Cylinder Hub | For 9800 & 80 Series Devices

The Sargent 98-0018 is a genuine OEM Outside Cylinder Hub designed to transmit the rotation of a keyed cylinder to the internal latch retraction mechanism. This heavy-duty component is essential for Sargent 9800 Series and 12-9800 (Fire Rated) Rim Exit Devices. Identified as Part #97 on technical diagrams, this hub is also the standard replacement for vintage 20 Series and 80 Series devices (manufactured prior to 2000), as well as many current-generation 80 Series models.

Institutional Grade Features & Benefits

• Cross-Generation Compatibility: A versatile repair part that services modern 9800 series hardware and legacy 80/20 series "flat-rail" devices.
  
• Precision Keyed Entry: Restores the smooth, "positive" feel of key rotation, preventing the cylinder from spinning or failing to retract the latch bolt.
• Durable Alloy Construction: Engineered to withstand the high torque and repetitive stress of exterior keyed entry points in schools, hospitals, and commercial buildings.
  
• Optional Retaining Ring: Can be paired with the 01-0005 Retaining Ring (available separately or as a selection) to ensure the hub remains securely seated within the chassis.
• Direct OEM Replacement: Swapping a worn or sheared hub (Part #97) is a professional-grade alternative to replacing the entire exit device chassis.
