16920 OEM AMEREX KP 275, 375, 475 BRACKET

The Amerex 16920 is the factory-original cylinder mounting bracket for Amerex KP restaurant fire suppression system cylinders — specifically the KP 275, KP 375, and KP 475 series wet chemical agent tanks. As the structural anchor for the KP system's agent supply, the 16920 bracket must provide code-compliant support that keeps the cylinder firmly positioned, vertically stable, and accessible for semi-annual service inspections under NFPA 96 requirements.

The Amerex KP system is one of the most widely deployed kitchen fire suppression system components in commercial restaurants, cafeterias, and food service operations. The 16920 bracket is engineered specifically for the cylinder diameter and weight of the KP 275, 375, and 475 models — the three most common tank sizes in the Amerex kitchen suppression system lineup. Using a non-OEM or undersized bracket on these tanks creates a structural liability risk: a bracket that fails under the weight of a fully charged cylinder can cause the tank to fall, potentially triggering an accidental discharge or injuring kitchen staff.

For fire protection contractors completing Amerex KP system installations or bracket replacements, the 16920 is the correct and only OEM-approved bracket for these cylinder models. It ships as a complete mounting kit ready for wall installation, making it a straightforward add to any amerex fire suppression system parts order. The bracket's design ensures cylinder positioning per the Amerex KP system manual layout requirements, which is critical for maintaining the system's UL 300 listed coverage geometry.

Wall Mounting Requirements

The 16920 bracket must be anchored to structural wall substrate per NFPA 96 and the Amerex KP system manual. In commercial kitchen environments with drywall, tile, or composite wall surfaces, locate wall studs or blocking before installation. Use fasteners rated for the total gross weight of the fully charged KP cylinder with a minimum 4:1 safety factor. Document bracket installation on the system inspection record.

Cylinder Positioning

Position the cylinder per the as-built drawings of the Amerex kitchen suppression system. The cylinder must be located to allow the actuation tubing to reach the MRM or PRM module without excessive bends, and to keep the agent distribution piping runs within the maximum lengths specified in the Amerex KP system manual. Incorrect cylinder positioning affects system hydraulics and can void the UL 300 listing.

Semi-Annual Inspection

During NFPA 96 semi-annual inspections, verify the 16920 bracket is secure, shows no signs of corrosion or fatigue, and the cylinder strap is tight. A loose cylinder is a red-tag deficiency. In high-vibration kitchen environments, check bracket fasteners for loosening at every inspection visit.

Is the 16920 compatible with the Amerex KP 600?

The 16920 is specifically sized for the KP 275, 375, and 475 cylinder series. The larger amerex kp 600 cylinder requires its own bracket due to its greater diameter and weight. Verify the correct bracket part number for your specific cylinder model using the Amerex KP system manual or Amerex fire suppression system parts catalog.

Can I use a generic pipe bracket instead of the 16920?

No. The 16920 is specifically engineered for the cylinder dimensions and weight of the KP 275/375/475 series. A generic bracket may not provide the correct cylinder diameter fit or load rating, creating a code violation and structural liability. Only OEM amerex fire suppression system parts should be used for cylinder support in UL 300 listed kitchen fire suppression system components installations.

Does the bracket include the cylinder strap?

Yes. The 16920 ships as a complete mounting assembly including the wall bracket and the cylinder retention strap. All hardware required for wall installation is included in the kit.
