3 Gallon Tank Bracket for Ansul R-102 429878

The Ansul 429878 is the OEM mounting bracket designed for 3-gallon ANSUL R-102 agent cylinders, providing secure wall or enclosure installation for the most common R-102 cylinder size. The 3-gallon cylinder — the ansul 3 gallon tank — is the standard agent cylinder in single-zone ANSUL R-102 restaurant fire suppression system installations protecting typical commercial kitchen configurations. The 429878 bracket keeps the cylinder positioned correctly per the ANSUL R-102 system design requirements, maintaining actuation tubing routing geometry and ensuring the cylinder is stable and accessible for semi-annual service inspections.

Built to meet UL and NFPA standards for commercial kitchen fire suppression system component mounting, the 429878 is part of the ANSUL fire protection system hardware catalog. Proper cylinder positioning via the 429878 bracket is essential to maintaining the ANSUL R-102 system's UL 300 listing — the actuation tubing routing and system hydraulics are all designed around the cylinder being in the correct location as specified in the ANSUL R-102 system design documentation. A missing, damaged, or incorrectly positioned bracket is a semi-annual inspection deficiency that must be corrected before the inspection record can be signed off.

The 429878 is available through authorized ansul distributors alongside the dual tank enclosure (429872) and related R-102 installation hardware. For fire protection contractors completing ANSUL R-102 installations or bracket replacements, the 429878 is the correct bracket for 3-gallon cylinder configurations. Inspect the bracket at every semi-annual NFPA 17A and NFPA 96 visit — verify the bracket is secure, shows no corrosion or damage, and the cylinder strap is tight. Document in the fire suppression system inspection record.

Install the 429878 per the ANSUL R-102 system design drawings and NFPA 96. Anchor to structural wall substrate or the dual tank enclosure (429872) as specified in the system design — verify the mounting substrate is rated for the gross weight of the fully charged 3-gallon cylinder. Position the cylinder per the ANSUL R-102 system documentation to maintain correct actuation tubing routing geometry. Inspect at every semi-annual NFPA 17A and NFPA 96 service visit: check bracket fasteners for loosening, verify the cylinder retention strap is tight, and confirm the cylinder position matches the system as-built drawings. Document in the fire suppression system inspection record.

Is the 429878 compatible with other ANSUL cylinder sizes?

The 429878 is sized specifically for the 3-gallon ANSUL R-102 cylinder. Other R-102 cylinder sizes use different brackets. The dual tank enclosure (429872) is used for dual-cylinder configurations. Always match the bracket to the specific cylinder size using the ANSUL R-102 system documentation — using an incorrectly sized bracket creates an unstable installation and is an NFPA 96 deficiency.

Can the 429878 be used inside the 429872 dual tank enclosure?

The 429878 is designed for wall or enclosure installation as specified in the ANSUL R-102 system design. Whether it installs inside the 429872 enclosure depends on the specific system design configuration. Consult the ANSUL R-102 system documentation and your authorized ansul distributor to confirm the correct bracket and enclosure configuration for your specific installation.
