Sargent 68-5070 Chassis Assembly for 59-8600 Delayed Egress Exit Device (LHR)

The Sargent 68-5070 is an OEM Chassis Assembly engineered for the Sargent 80 Series exit device platform. Specifically compatible with the 59-8600 Delayed Egress exit device, this chassis is the core operating component that receives force from the push rail when the push bar is depressed and translates that action into latch retraction to allow egress. This part is supplied in the Left Hand Reverse (LHR) hand configuration. Because the device-model prefix designates a life-safety function — 59- indicating Delayed Egress — this chassis is not interchangeable with chassis assemblies carrying different model prefixes. Always verify the full model designation, including prefix, before ordering.

Delayed Egress Function — What It Means

A Delayed Egress exit device (prefix 59-) is designed to introduce a timed delay — typically 15 or 30 seconds — before the latch fully retracts upon push-bar activation. This function is commonly specified in healthcare, retail, and institutional occupancies to deter unauthorized egress while maintaining full compliance with life-safety and fire-code egress requirements. Because the chassis assembly is integral to the timing and release mechanism, using the correct, prefix-matched chassis is critical to proper device operation and code compliance.

Institutional Grade Features & Benefits

• OEM Sargent Component: Factory-original chassis assembly ensures precise fit, finish, and performance within the 80 Series exit device family.
• Core Operating Mechanism: The chassis receives push-rail force and drives latch retraction — the central mechanical action of the exit device.
• Life-Safety Critical Fit: The 59- Delayed Egress prefix designates a specific internal mechanism; this chassis is engineered exclusively for that configuration and must not be substituted with non-matching prefix parts.
• Correct Handing (LHR): Supplied as Left Hand Reverse — confirm door handing before ordering using the handing diagram provided with this listing.
• 80 Series Platform Compatibility: Designed and manufactured to the dimensional and mechanical tolerances of the Sargent 80 Series exit device, supporting reliable long-term field performance.
• Replacement & Repair Application: Ideal for facilities maintenance, service contractors, and door hardware distributors restoring or repairing Sargent 59-8600 Delayed Egress exit devices to full operational condition.
