Sargent 8510 Narrow Stile Rim Exit Device
The Sargent 8510 is a professional-grade Narrow Stile Rim Exit Device specifically engineered for use on glass doors with slim aluminum frames. Combining sleek aesthetics with high-security performance, the 8510 provides a single-point rim latching solution that fits where standard exit devices cannot. Whether installed on single doors or double doors with a mullion, this Grade 1 panic bar delivers the "quiet operation" and "solid security" that facility managers and architects demand.
Precision Engineering for Aluminum & Glass Doors
Designed to accommodate a minimum stile width of 2", the Sargent 8500 Series is the industry standard for modern storefronts and narrow-profile metal doors. Despite its slim footprint, it is a powerhouse of durability, certified to ANSI/BHMA A156.3 Grade 1 standards. The device features a 3/4" throw stainless steel latchbolt, ensuring reliable engagement and long-term resistance to wear and tear in high-traffic commercial environments.
Safety Compliance and Electrified Integration
Safety is uncompromised with the 8510. It is UL305 Panic Listed and, when ordered with the 12-prefix, it is UL10C Fire Rated. To meet the needs of modern building automation, the 8510 supports a full suite of electric options, including Remote Latch Retraction (56-ELR) and Request-to-Exit (55-RX) monitoring. For the most reliable electrical connection, we recommend using a QC12 Electrolynx connector on the associated hinge to facilitate a clean, "plug-and-play" installation.

Ordering & Handing Notes

To ensure a perfect fit, Sargent rails are factory-cut to size; please provide the exact door width upon order placement. Additionally, door handing information (LHRB or RHRB) is required to ensure the device and any associated trim are correctly configured for your opening. For doors thicker than 1-3/4", specify the dimensions and use the 31- prefix. For high-use areas where keys are preferred for daily dogging, consider the 16- cylinder dogging option.
