Sargent 68-2279 Through-Bolt Set for 8800 & 12-8800 Rim Exit Devices

The Sargent 68-2279 is a set of four through-bolts (thru-bolts) engineered specifically for mounting Sargent 8800 Series (non-fire-rated) and 12-8800 Series (fire-rated) rim exit devices to doors that lack internal reinforcement. Where standard machine-screw mounting is not sufficient, these through-bolts provide the secure, code-compliant fastening required for commercial panic hardware installations.

What Are Through-Bolts and When Are They Required?

Through-bolts pass completely through the door stile from face to face, distributing load across the full door thickness rather than relying on threaded engagement with the door material alone. This method is the preferred — and often required — fastening approach for exit devices installed on:

• Hollow metal doors without internal reinforcement at the device location
• Steel-clad doors (steel skin over a hollow or composite core)
• Solid and hollow-core wood doors
• Aluminum stile doors

Building and fire codes, as well as UL fire-exit hardware listing requirements, specify that exit devices on fire-rated openings must be positively fastened. Through-bolts satisfy this requirement on door types that cannot support standard screw-only attachment. Always verify local AHJ (Authority Having Jurisdiction) requirements when specifying hardware for rated openings.

Compatible Sargent Exit Device Series

• Sargent 8800 Series — Wide-stile rim exit device, non-fire-rated (panic hardware)
• Sargent 12-8800 Series — Wide-stile rim exit device, fire-rated (fire exit hardware, UL10C listed)

The 8800 Series is Sargent's primary rim exit device line, rated ANSI/BHMA A156.3 Grade 1. The 12-8800 prefix denotes the UL-listed fire-rated variant required on labeled fire door assemblies. Both series use the same through-bolt hole pattern, making the 68-2279 set interchangeable across rated and non-rated applications within this device family.

Key Benefits

• Set of 4 bolts — complete fastener set for one exit device installation
• Designed for doors without internal reinforcement — hollow metal, wood, steel-clad, and aluminum
• Maintains the structural integrity and load-bearing performance expected of Grade 1 commercial panic hardware
• Supports compliance with fire exit hardware installation requirements on rated door assemblies
• Genuine Sargent replacement part — engineered to match device tolerances and maintain UL listing integrity on 12-8800 installations

Typical Applications

• New installation of Sargent 8800 or 12-8800 rim exit devices on unreinforced doors
• Replacement of missing or damaged through-bolts on existing panic hardware installations
• Retrofit installations where door prep does not include internal blocking or reinforcement plates
• Schools, commercial offices, healthcare facilities, and any occupancy requiring compliant egress hardware on hollow or composite doors
