Sargent 68-6045 Chassis Assembly for 80 Series Exit Device — HC4, RHRB

The Sargent 68-6045 is a genuine OEM chassis assembly engineered for the Sargent 80 Series exit device. Also referenced as the HC4 chassis, this core operating component serves as the mechanical heart of the exit device: when the push bar is depressed, the push rail transfers force directly to the chassis, which in turn retracts the latch bolt to allow immediate, code-compliant egress. Designed specifically for Right Hand Reverse Bevel (RHRB) applications, this replacement chassis restores the precise operation your 80 Series device requires without the cost of a full unit replacement.

Institutional Grade Features & Benefits

• OEM Sargent Component: A genuine factory-spec chassis assembly built to the same tolerances as the original, ensuring reliable, repeatable latch retraction cycle after cycle.
• Core Egress Mechanism: Directly receives push-rail force and translates it into smooth latch retraction — the fundamental action that makes the exit device function for life-safety egress.
• Targeted Compatibility: Engineered exclusively for the Sargent 80 Series, specifically compatible with the 8715 exit device model. Ensures a precise fit with no modification required.
• RHRB Handing: Manufactured for Right Hand Reverse Bevel door applications. Confirm your door handing before ordering; a handing reference diagram accompanies this listing.
• Cost-Effective Repair Solution: Replaces only the worn or damaged chassis rather than the entire exit device, reducing parts cost and minimizing door downtime in commercial, institutional, and industrial facilities.
• HC4 Designation: Carries the HC4 chassis classification, making cross-referencing against Sargent service documentation and parts lists straightforward for locksmiths and facility maintenance professionals.
