Af090 Retrofit Restraining Strap For Seismic Safety

The Af090 Retrofit Restraining Strap secures existing fire sprinkler systems against earthquake damage by preventing pipe dislodgement and structural failure. Designed for integration into commercial and industrial wet, dry, or preaction fire sprinkler assemblies, this specialized component reinforces piping layouts without requiring a full system replacement. It satisfies strict seismic safety mandates to ensure compliance with NFPA 13 standards for installations located in earthquake-prone zones.

Engineered for reliable performance during seismic events, this restraining strap lowers the risk of catastrophic water damage caused by broken sprinkler pipes. Maintenance personnel can easily install the hardware using standard tools, minimizing labor downtime during structural upgrades.

• High-Strength Steel: Constructed from corrosion-resistant steel that withstands harsh mechanical environments and maintains long-term structural integrity.
• Adjustable Fit: Features an adjustable length and a secure fastening hook to accommodate various pipe diameters and complex layout configurations.
• Retrofit Compatibility: Engineered specifically to fit existing fire sprinkler piping without requiring complex modifications or system redesigns.
• Seismic Code Compliance: Exceeds current building code requirements to maintain crucial fire protection functionality during seismic occurrences.

Contractors must verify local Authority Having Jurisdiction (AHJ) requirements and consult manufacturer technical specifications prior to executing seismic retrofit installations.
