Built to PDI-G101 standards and manufactured in Rockford, IL, the RP-100 is the go-to choice for restaurants, cafeterias, and institutional kitchens that demand lasting grease management performance.
Key Features of the Rockford RP-100
Six engineering decisions that make the RP-100 the trusted choice for busy commercial kitchens worldwide.
All-Welded Steel Construction
Every seam is fully welded — no bolted panels that can work loose over time. The robust steel shell resists corrosion from harsh kitchen effluent and supports decades of service in demanding environments.
Dual Installation Modes
Designed for both on-the-floor and flush-with-the-floor installations, the RP-100 adapts to your facility layout without requiring special fittings or structural modifications.
Nonskid Diamond Tread Cover
The removable 3/16" diamond tread plate cover is rated for pedestrian traffic and secured with stainless steel flat-head screws, allowing safe walk-over access and quick cleanout without tools.
Heavy-Duty Leak-Proof Gasket
A precision-engineered gasket seals the cover to the body, preventing odors, vermin intrusion, and any grease seepage — maintaining a sanitary kitchen floor regardless of water pressure fluctuations.
Enamel Coating Inside & Out
A durable enamel finish coats both the interior and exterior surfaces, protecting the steel from the grease, detergents, and acidic waste typical in commercial kitchen wastewater streams.
PDI-G101 Compliant
Manufactured to the specifications of the Plumbing & Drainage Institute PDI-G101 standard, ensuring the RP-100 meets or exceeds municipal health, plumbing, and environmental requirements across the United States.
Optional Upgrade Features: The RP-100 is available with optional add-ons at additional cost — including an anchor flange, epoxy coating upgrade, full stainless steel construction, integral extension, alternate inlet/outlet sizing, aluminum cover, and threaded connections.
